Abstract
Approaches presented herein provide systems and methods for dynamic transport switching for messages transmitted within a compute environment. Messages generated by publishers may be evaluated within a client library against one or more rules to select a transmission protocol for the message. If a message has a parameter exceeding a threshold, a direct peer-to-peer transmission protocol may be selected to bypass transmission of the message to an intermediary. The client library may generate a smaller message for publication to one or more subscribers. The subscribers may then directly communicate with the client library in order to transmit the message.
Description
BACKGROUND

Communication systems may include a publish/subscribe messaging service where a publisher may generate a message and transmit that message to a broker for distribution to a number of different subscribers. These systems often permit asynchronous communications across multiple sessions for different applications. For example, a publisher may provide the message to the broker, which then pushes the message to the subscribers, either directly or responsive to a request from the subscribers. Data transmission may be performed over a selected transmission protocol, such as Transmission Control Protocol (TCP), to open two-way connections to the broker from the subscribers. This procedure may work when message size is small, or when there are a small number of users, but as message size increases and/or a user base increases, latency and/or reliability may reach unacceptable levels.

DETAILED DESCRIPTION

In the following description, various embodiments will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the embodiments may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.


Approaches in accordance with various embodiments can be used for transmission of information (e.g., messages, data, storage information, metadata, combinations thereof, etc.) within a compute environment. An application running within the compute environment may include a client library to evaluate, transmit, and/or receive messages from a user of the application. Users that generate messages may be referred to as publishers, while users that receive and/or consume messages may be referred to as subscribers. A user may be both a publisher and a subscriber based, at least, on a present interaction with one or more messages in the system. For example, a user may be a publisher when generating a message, and a subscriber when receiving a message. Messages may include different components, including at least metadata and data. Upon receipt (e.g., generation, creation, etc.) of a message, the client library may evaluate the message based on one or more factors (e.g., message size, number of subscribers, message type, etc.) and, based on the evaluation, may make a determination in accordance with one or more rules regarding how to transmit the message. For example, a message may be sent in its entirety, for example to a broker (e.g., a message broker, a publication/subscription service, a “Pub/Sub”), or only a portion of the message, such as the metadata or information associated with the metadata, may be sent to the broker. At the broker, transmission (either the entire message or just the metadata) may then be published or provided to different end users (e.g., subscribers) that can then either use the message or receive information regarding how to retrieve the message. In at least one embodiment, the client library evaluates data transmission on a per message basis to determine an appropriate protocol for message transmission, which may include peer-to-peer transmission, going through the Pub/Sub, or a direct connection, such as remote direct memory access (RDMA), among other options. Accordingly, systems and methods may remove distance between clients and allow applications executing within the compute environment to access protocols within a client library and use the broker as an intermediary to transmit information, which may include either entire messages, metadata, information associated with the metadata data, and/or the like. As a result, transmission may be optimized based on different parameters.


One or more embodiments of the present disclosure include dynamic switching of data transport protocols within a compute environment. Different transport protocols may be selected based, at least, on properties of information (e.g., number or frequency of messages, size or type of data, etc.) transmitted between users of the computer environment. In at least one embodiment, a set of rules may be used when evaluating properties of the information to select a particular protocol for a given component of information. For example, selecting a particular protocol may include analyzing a size of a session, analyzing a location of clients within a session, determining a property of the protocol (e.g., speed, reliability, etc.), and then selecting a protocol from a pool of protocols. Further, as noted herein, analysis may also include evaluation of message size, evaluation of message properties (e.g., data type, acquisition time, etc.). Additionally, various embodiments may further preserve message ordering and provide automatic scaling.


Various other such functions can be used as well within the scope of the various embodiments as would be apparent to one of ordinary skill in the art in light of the teachings and suggestions contained herein.



FIG. 1 illustrates an example of a communication environment 100 that may be used with embodiments of the present disclosure. In this example, the communication environment 100 may include a distributed computing environment 102 (e.g., a cloud environment) in which one or more user devices 104A-104N, associated with users, may interact with an application 106 executing within the environment. For example, the user devices 104A-104N may interact with an application 106 via one or more network connections (e.g., over the internet). In certain embodiments, communication with the application 106 may be dependent on whether or not the user devices 104A-104N provide appropriate credentials and/or include appropriate permissions to access the application 106. The user devices 104A-104N may be associated with programs or applications executing on hardware that is shared by one or more of the user devices 104A-104N. For example, the users of the devices may be executable software programs that perform one or more tasks, such as updating a database responsive to a determination that a file has been added to or removed from the database. Accordingly, the user devices 104A-104N and/or the associated users of those devices 104A-104N may be programmed to execute automatically or semi-automatically. Furthermore, in one or more embodiments, at least some of the users of the user devices 104A-104N may be human users.


The application 106 may be one or more hosted or native applications within the environment 102 that permits communications between (e.g., both to and/or from) the user devices 104A-104N and the environment 102. For example, one or more of the user devices 104A-104N may submit a request and/or a command to the application 106 for execution of an action or to receive information from the application 106. In certain examples, the user devices 104A-104N and/or the associated users may act as a publisher and/or a subscriber. A publisher may refer to a user device 104 and/or an associated user that provides information to the application 106 that will be broadcast to other users associated with the application 106. For example, the publisher may be a device and/or a service executing on a device that provides information to the application 106 that broadcasts a command to an associated device. A subscriber may refer to a user device 104 and/or an associated user that receives information from the application 106, such as to execute one or more commands. For example, the subscriber may be a device and/or a service executing on a device that is programmed to execute certain functions based on associated actions, such as a backup utility that begins a data backup procedure upon receipt of a message that one or more files at a certain storage location have been updated.


In operation, the environment 102 may be used in a variety of different formats or operational modes. For example, the environment may include clients that operate in a live-sync session, storage service notification subscribers, simulation clients, and/or additional clients. As a result, protocols for communication between clients may be different. By way of non-limiting example, certain communications may use a remote call procedure (RPC) while others may use an in-memory storage structure, such as Redis. These different protocols create unique challenges for different clients. For instance, clients that use a Redis protocol may not consider latency to be a critical requirement compared to guaranteed message delivery. As another example, clients that use RPC protocols (which may be custom protocols) can choose between guaranteed delivery and low latency. Systems and methods of the present disclosure may be used to select a communication protocol, based on one or more rules, and then prepare for information transmission based on that selection. As a result, different clients may use different protocols that are dynamically switched based on certain selection criteria.


In the illustrated example, the application 106 includes an execution component 108 and a client library 110. The execution component 108 may include functionality to operate the application 106, such as an interface to receive commands from the user devices 104A-104N, a communication system to transmit information throughout the application 106 and/or the environment 102, and other functionality. The client library 110 may manage connections to the environment 102 and/or particular services within the environment 102, manage local state and resources, and implement connections between other client libraries for different applications 106 and/or applications 106 running on different instances.


The client library 110 may further evaluate or otherwise be used to determine a communication protocol for a given transmission from the user devices 104A-104N. In at least one embodiment, a message (e.g., data, information, etc.) is received at the application 106 from one or more of the user devices 104A-104N. The message may include different components or segments of information, including at least data and metadata. The data may be associated with a command or instruction within the message, as well as telemetry information and/or other information that may be used by one or more subscribers in order to execute various commands or tasks. The metadata may include information about the message, such as a size of the message, content of the message, the publisher of the message, a storage location for the message, and/or additional information. In at least one embodiment, the metadata is smaller than the data (e.g., the metadata occupies less physical memory space than the data). As a result, it may be faster to transmit just the metadata, or information describing the metadata, instead of the data and/or the message in its entirety.


The client library 110 may evaluate the message against one or more rules 112 and, based on the evaluation, determine whether to transmit the entire message to a broker 114 (e.g., publisher/subscriber (“Pub/Sub”)) or to transmit only the metadata and/or information describing the metadata. For example, the one or more rules 112 may be based on a variety of factors associated with the message, the application 106, a node hosting the application 106, and/or other information or combinations thereof. In at least one embodiment, message size may be a determining factor, where a message including data having a size (e.g., space occupying physical memory) above a certain threshold is not transmitted in its entirety, and instead, only the metadata and/or information describing the metadata is sent to the Pub/Sub 114. The Pub/Sub 114 may then publish the information associated with the metadata and one or more subscribers may receive instructions or information, such as a location of the data and/or the entire message, for retrieval in accordance with one or more parameters, such as a selected transmission protocol and/or an ordering for data receipt. The information associated with the metadata may be a smaller quantity of data that describes a message, provides an identifier for the message, and also provides information for the data, such as a pointer to a specific memory location to retrieve the data, among other options. As another example, a number of subscribers or a location of the subscribers, among other options, may also be used to determine which components of the message to transmit to the Pub/Sub 114. For example, a number of subscribers exceeding a certain number may be deemed as appropriate for transmission of only the metadata and/or the information associated with the metadata. In at least one embodiment, two or more rules may be used in order to make a determination of message transmission. Furthermore, while examples are provided as thresholds, additional evaluations may take place, such as determinations of data type, physical locations of subscribers, environment 102 bandwidth/usage, and/or the like. Accordingly, different applications 106 and/or their respective users or administrators may develop different sets of rules 112 in order to dynamically evaluate and adjust transmission protocols for different information.


In at least one embodiment, the client library 110 hides an implemented protocol such that implementation details are not visible to or accessible to the client and/or users. As a result, the client may be presented with an application programming interface (API) instead of a specific protocol. Based on this implementation, the client may be the entity to run a portion of the cost (e.g., compute costs) of the Pub/Sub 114.


Various embodiments may also incorporate a variety of services 116 and/or storage locations 118 of the environment 102 into systems and methods of the present disclosure. For example, services 116 may be integrated into the environment 102 and include functionality such as monitoring, searching, and/or administrative functions, such as credential screening and/or authentication services. Moreover, in at least one embodiment, the storage services 118 are external services that may run in the same cluster or in a different cluster.


In operation, selection of different protocols may further affect other aspects of the environment, such as availability of libraries, programming languages, API applications, and/or the like. For example, depending on the language used by the Pub/Sub 114, different libraries or protocols may be preferable over others. Accordingly, as noted herein, these considerations may also serve as one or more factors associated with the rules 112.


Embodiments of the present disclosure may permit transportation of information between services using a variety of different protocols, including internet transport protocols, such as TCP, hypertext transfer protocol (HTTP), user datagram protocol (UDP), and/or the like, along with direct data transport protocols, such as RDMA. For example, when RDMA is selected as the transport protocol, data exchange may occur over a separate channel to transmit data between clients. RDMA may be used in circumstances where only metadata and/or information associated with the metadata is published to the Pub/Sub 114. Clients that want to retrieve the information may then fetch the information directly from the publisher using RDMA transport in order to minimize a total latency of operation and to maximize bandwidth by forming the direct data transfer with the publisher instead of using the Pub/Sub 114 as an intermediary for the data transmission.



FIG. 2 illustrates an example architecture 200 in which embodiments of the present disclosure may be implemented. As noted herein, various components of the architecture 200 may be shown as being part of or incorporated within different environments, such as within or part of the Pub/Sub 114. The arrangement shown in FIG. 2 is for illustrative purposes only and various components, systems, services, or clients may be executed on different clusters or at different logical locations and/or underlying hardware while being in communication with one or more other services or clients. For example, the services 116 may be integrated into the Pub/Sub 114.


In this example, external services 202A-202N may interact with or otherwise communicate with the Pub/Sub 114 via a front end service 204. In this example, the front end service 204 acts as an API gateway to send and receive messages associated with the Pub/Sub 114. For example, a load balancer for a given cluster may send requests to the front end service 204 directly, which may then direct the messages to the appropriate sub-service or sub-system of the Pub/Sub 114. In at least one embodiment, each cluster node executing within the environment runs one instance of the front end service 204.


In at least one embodiment, the front end service 204 communicatively connects to a control service 206, a replication service 208, and a message queue service 210. Various other components and sub-systems of the Pub/Sub 114 may also be accessible or in communication with the front end service 204 and the illustration in FIG. 2 is not intended to be an exhaustive or limiting illustration of connectivity. In at least one embodiment, the control service 206 may send and/or receive control messages, such as messages to connect to a certain service, to join a topic, to send data, and/or the like. Furthermore, the connection to the replication service 208 may be for implementation of one or more replication protocols that permit groups of clients to work together on a common scene or resource. Additionally, the connection to the message queue service 210 may be used to send and receive data messages.


The control service 206 may be considered a control plane for the Pub/Sub 114 to balance a load between multiple queues and the replication services. For example, the control service 206 may receive information related to different topics that are used to link or otherwise direct messages from the different applications 106. Information may be grouped or otherwise organized by topic. As a result, a request for a new topic or to make changes may be managed by the control service 206. The control service 206 may also manage or otherwise monitor a state of a given cluster.


In at least one embodiment, the control service 206 has full visibility over the topic and client distribution across queue services. However, the control service 206 may not have data about the number of messages sent and received for a queue instance. This information may come from the front end service 204. For example, the front end service 204 may keep a connection to control service 206 to report active topics and clients and to supply monitoring data. In some embodiments, monitoring data may be provided by the services 116. This information may be used by the control service 206 to manage various aspects of the Pub/Sub 114. For example, the control service may consider the number of clients, the number of topics, and the number of messages as input for calculating locations where new topics are created. The control service 206 may use a number of live sync clients per live sync session, in addition to metrics per message, to choose locations where new sessions are hosted.


For each topic, the control service 206 creates a new data flow in the queue service 210. Each client, registered as subscribers, has a queue directly connected to an exchange. The queues are setup as push queues, where front ends represent the clients and are registered as queue clients. In at least one embodiment, the control service 206 is a stateless service. The queue service 210 may also integrate with and/or use a forwarder 212 to transmit or otherwise broadcast information, either separate from or in conjunction with the front end service 204.


In this example, the replication service 208 may include a replication protocol to collect, serialize, and apply changes to objects that are being edited or otherwise viewed by multiple users concurrently. These changes may be applied serially and then used to update the objects. The message queue service 210 may be used to take and manage the main load of the Pub/Sub 114. For example, load may be distributed across multiple instances of the message queue service 210. As a result, the message queue service 210 may be scalable to accommodate increases or decreases in message traffic to the Pub/Sub 114. In at least one embodiment, the queue service 210 is used to, at least in part, maintain strict ordering between messages. For example, metadata for different messages may drive ordering for how messages are received at different clients. As a result, even if data is available within a client library, the presence of the data is not announced to the applications until the metadata and/or information associated with the metadata is received. However, in at least one embodiment, information may be consumed out of order, for example, if one or more applications are tuned or otherwise configured to pull information in such a manner. In at least one embodiment, the queue service 210 may be a broker service that acts as an Advanced Message Queuing Protocol (AMQP) exchange. The workload is distributed across multiple instances of the queue service 210 and the cluster scales as more queue services 210 are deployed.


In operation, communication is between the respective client libraries 110A, 110B and the front end 204. While the illustrated embodiment only includes two client libraries 110A, 110B, other embodiments may include more or fewer libraries 110A, 110B associated with more or fewer applications 106A, 106B. For example, different applications may be scaled on a number of instances or executing across different clusters. The applications 106 receive information from a publisher, such as the external services 202A-202N or some other user of the applications 106. In the initial message, the client library 110 announces the type of supported direct connections. The client libraries 110 that are connected to the same topic establish direct connections in addition to the connection to the service. When it is possible, the client library 110 publishes message metadata and/or information associated with message metadata through the Pub/Sub service 114 and sends the payload directly to the other clients. As noted, there may be multiple factors that limit the use of direct connection, such as, for example, network protocols, distance between clients, size of messages, and number of clients in the topic.


In the direct connection case, the order of the messages is enforced by metadata messages received from the service. When more than two clients are connected to the same topic, the order of messages received from the client through a direct connection may vary based on the distance between clients. The metadata received from the service sets the order of the data received from direct connections.


In at least one embodiment, the client libraries 110 establish TCP connections to a Pub/Sub service 114. For each connection, the client libraries 110 keep the TCP connection to the service 114, local state, and allocated system resource-memory, network, and OS threads. Internally, the client libraries 110 may also allocate one thread per service connection to manage asynchronous execution of send and receive operations. In at least one embodiment, services for memory management are also deployed due to effects on latency of message delivery. For example, memory copies may be minimized. On the read path, when the client libraries 110 allocate memory, the memory should be freed by the client libraries 110. For example, the client libraries 110 may include a structure that represents memory blocks in system memory or GPU memory. However, the structure does not contain memory, but instead contains pointer(s), size information, and some metadata about memory. When the application 106 sends a memory block, the application 106 creates the structure and waits for the client libraries 110 to report that the memory can be released. Similarly, when the client libraries 110 notify the respective applications 106 that there is a new message, the applications 106 notify the client libraries 110 when the memory can be deallocated.


Various embodiments may also deploy, for example through the control service 206, various functionality regarding usability and operations of the Pub/Sub 114. For example, as part of the rules 112 or as a separate system, the client libraries 110 may operate using a retry policy to retry operations multiple times when there are problems due to transient errors. In at least one embodiment, reconnections may be used to overcome such problems, where the client library 110 may select a different front end service 204 to address issues. Retry policies may be defined by application 106 for each API call and may delineate types of retries (e.g., none, linear, exponential), parameters for the retries, a total number of retries, and/or a default retry policy.


Further embodiments may deploy additional functionality, such as circuit breakers and metric collection via the services 116. For example, the circuit breaker may be used to prevent long timeouts when the service cannot be connected. In at least one embodiment, one circuit breaker per connection to a Pub/Sub instance is deployed. Initially the circuit breaker may be set to be in the closed state and all the requests can be executed immediately and/or without significant delay. However, if the connection to the service fails and cannot be restored for some period, the circuit breaker transitions to an open state such that all attempts for connection fail immediately and/or without significant delay. After some period, the state may be changed to semi-open to permit new attempts for connection to the service. If the attempts are successful, the state of the circuit breaker is back to closed and connection is back to normal. Collected metrics may be aggregated per API and sent to the front end service at some predefined intervals.


In at least one embodiment, messages between the applications 106 and the front end service 204 may take a variety of forms. For example, the messages may be data, files, textures, meshes, geometry, and/or various other types of information. Accordingly, the client libraries 110 may evaluate the size of the message in its totality in order to select a communication protocol that provides a balance between one or more factors, such as bandwidth and latency, among other options. In at least one embodiment, a number of subscribers for a given publisher may also be used in determining a communication protocol. For example, a single publisher may be overwhelmed if a large number of subscribers attempts to access information close in time to one another. Systems and methods may permit scaling of the service to handle a large number (e.g., above a threshold number) of subscribers. Nodes that are used to send data may be duplicated such that a subscriber obtains the same information, regardless of which node provides the information. Such a system may permit direct connection (e.g., transmission over RDMA) when there are a threshold number of subscribers attempting to access information at the same time.


Various embodiments may organize and/or otherwise publish information in accordance with one or more topics, which may be a logical grouping of information. Different applications may publish to a single topic or to multiple topics, for example, if the applications have sufficient permissions to publish to those topics. Furthermore, each individual Pub/Sub 114 within the environment may have hundreds or thousands of different topics. Because a common client library can be used to publish to one topic and subscribe to a different topics, various embodiments may optimize communication at a topic level based on individual messages. For example, services may exist that perform actions based on one or more trigger events. As one non-limiting example, a trigger event may include changing a file, and the subsequent actions may include indexing the file that was changed, tagging the file that was changed, updating a directory for search, and so on. While each of these services performs different actions, they may all be subscribed to the same publisher, which tells each service that the file was changed, and based on that information, additional operations may be executed.


Systems and methods may be directed toward an internal service that may remove distance between clients executing within an environment. A publisher may transmit information (e.g., a message) through an application to a client library. This message may include multiple components, such as data itself and metadata, among other options. The client library may evaluate the message, based on one or more rules, to select a transport protocol for the message. If it is determined that a direct connection is a preferable transport protocol, the client library may not send the entire message to a Pub/Sub, but instead, will provide metadata and/or information associated with the metadata. The Pub/Sub may then publish this information and a subscriber may obtain information for how to retrieve the message via a direct connection. If it is determined that a direct connection is a preferable transport protocol, the client library may send the entire message to the Pub/Sub.



FIG. 3A illustrates a sequence diagram 300 that can be implemented with embodiments of the present disclosure. There may be more or fewer steps within the sequence diagram, such as steps to publish information, obtain metrics, balance loads, generate new instances, and/or others. In this example, the application 106A generates information associated with a message and sends 302 the message to the client library 110A. Sending the message may include generating data that is marked for transmission and subsequent access of the message by the client library 110A. The client library 110A may perform an evaluation of the message 304, for example against a set of rules, to dynamically select a transport protocol for the message. For example, the client library 110A may evaluate one or more properties of the message, such as message size, among other options, along with and/or alternatively one or more properties of the environment and/or subscribers associated with the pub/sub to select the transport protocol. In this example, a direct connection is selected, and information associated with the message metadata—but not the entire message itself—is provided 306 to the front end 204 of the Pub/Sub 114.


Within the Pub/Sub, the message information may be transmitted 308 to a queue service 210, and the message information may be published 310 to the application 106B. The application 106B may determine a location of the message itself and then submit a request 312 to pull the information from the client library 110A, for example via a direction connection. The connection may be established and then data transmission may occur 314 between the client libraries 110A, 110B. As a result, intermediate data transmission of the message itself from the client library 110A to the Pub/Sub 114 is eliminated by using a direct connection between the respective client libraries 110A, 110B.



FIG. 3B illustrates a sequence diagram 320 that can be implemented with embodiments of the present disclosure. In this example, the application 106A generates information associated with a message and sends 322 the message to the client library 110A. As noted, sending the message may include generating the information for the message in a manner that can be accessed by the client library 110A. The client library 110A may perform an evaluation of the message 324, for example against a set of rules, to dynamically select a transport protocol for the message. For example, the client library 110A may evaluate one or more properties of the message, as noted herein, to select the transport protocol. In this example, a connection using the Pub/Sub 114 as an intermediary is selected and the message is provided 326 to the front end 204 of the Pub/Sub 114. Within the Pub/Sub 114, the message may be transmitted 328 to a queue service 210, and the message may be published 330 to the application 106B. The application 106B may then submit a request 332 to pull 334 the message from the Pub/Sub 114 to the client library 110B. Such a system may be useful for smaller messages that can be transmitted with high quality over the two-way connection established between the front end 204 and the application 106B.



FIG. 4 illustrates an example process 400 for dynamically selecting a transport protocol. It should be understood that for this and other processes presented herein that there can be additional, fewer, or alternative operations performed in similar or alternative order, or at least partially in parallel, within the scope of various embodiments unless otherwise specifically stated. In this example, a message is received from an application, for example at a client library associated with the application 402. The message may include data and metadata. For example, the data may include a variety of different data types and information, such as text data, image information, textures, meshes, and/or the like. The metadata may provide one or more properties of the data, such as file formats, storage location, date obtained, and/or the like.


In at least one embodiment, the message may be evaluated, e.g., at a client library, against one or more rules 404. The rules may be associated with selection of a transport protocol for the message. The one or more rules may be based on a variety of factors, such as message size, client locations, number of subscribers associated with the message, and/or the like. In at least one embodiment, multiple rules are applied to the messages. The rules may include threshold evaluations, where a message size exceeding a threshold may be designated for a particular transport protocol and a message size less than a threshold may be designated for a different transport protocol. Furthermore, additional evaluation may be applied after the initial binary evaluation.


A transport protocol may be selected 406 based on the evaluation and, thereafter, different actions may be initiated in order to transmit the message. When a two-way protocol, such as a TCP connection, is selected, the message may be transmitted to a broker 408. When a direct protocol, such as a RDMA connection, is selected, the message itself may not be transmitted to the broker, and instead, message information may be generated 410. The message information may be based, in part, on the metadata, and may further include information such as a storage location for the message, a message identifier, and/or the like. The message information may then be transmitted to the broker 412 and that message information may be broadcast to one or more subscribers. The subscribers may then fetch or pull the information from the client library by establishing a direct data connection 414, which may then be used to transmit the message to the subscriber 416. In this manner, different protocols may be selected based on a variety of factors at a message level, thereby permitting dynamic switching and adjustment to message transmission within an environment.



FIG. 5 illustrates an example process 520 for transmitting messages between a publisher and a subscriber. In this example, a broker publishes a first publication that is received by a subscriber 522. The first publication may be associated with a message from the first publisher. The subscriber may request the first message from the broker 524 and establish a two-way connection to the broker 526. Using the two-way connection, the subscriber may receive the first message from the broker 528.


In at least one embodiment, a second publication may be received by the subscriber 530. The second publication may be associated with a second message. In at least one embodiment, the second publication is evaluated by the subscriber to determine a storage location for the second message 532. For example, the storage location may be a client library of the publisher. A direct connection between the subscriber and publisher may be established 536 and, using the direct connection, the subscriber may receive the message directly from the publisher. In this manner, the broker may be removed as an intermediary for transmitting the second message.


As discussed, aspects of various approaches presented herein can be lightweight enough to execute on a device such as a client device, such as a personal computer or gaming console, in real time. Such processing can be performed on, or for, content that is generated on, or received by, that client device or received from an external source, such as streaming data or other content received over at least one network. In some instances, the processing and/or determination of this content may be performed by one of these other devices, systems, or entities, then provided to the client device (or another such recipient) for presentation or another such use.


As an example, FIG. 6 illustrates an example network configuration 600 that can be used to provide, generate, modify, encode, process, and/or transmit image data or other such content. In at least one embodiment, a client device 602 can generate or receive data for a session using components of a content application 604 on client device 602 and data stored locally on that client device. In at least one embodiment, a content application 624 executing on a server 620 (e.g., a cloud server or edge server) may initiate a session associated with at least one client device 602, as may utilize a session manager and user data stored in a user database 636, and can cause content such as one or more digital assets (e.g., object representations) from an asset repository 634 to be determined by a content manager 626. A content manager 626 may work with an image synthesis module 628 to generate or synthesize new objects, digital assets, or other such content to be provided for presentation via the client device 602. In at least one embodiment, this image synthesis module 628 can use one or more neural networks, or machine learning models, which can be trained or updated using a training module 632 or system that is on, or in communication with, the server 620. This can include training and/or using a diffusion model 630 to generate content tiles that can be used by an image synthesis module 628, for example, to apply a non-repeating texture to a region of an environment for which image or video data is to be presented via a client device 602. At least a portion of the generated content may be transmitted to the client device 602 using an appropriate transmission manager 622 to send by download, streaming, or another such transmission channel. An encoder may be used to encode and/or compress at least some of this data before transmitting to the client device 602. In at least one embodiment, the client device 602 receiving such content can provide this content to a corresponding content application 604, which may also or alternatively include a graphical user interface 610, content manager 612, and image synthesis or diffusion module 614 for use in providing, synthesizing, modifying, or using content for presentation (or other purposes) on or by the client device 602. A decoder may also be used to decode data received over the network(s) 640 for presentation via client device 602, such as image or video content through a display 606 and audio, such as sounds and music, through at least one audio playback device 608, such as speakers or headphones. In at least one embodiment, at least some of this content may already be stored on, rendered on, or accessible to client device 602 such that transmission over network 640 is not required for at least that portion of content, such as where that content may have been previously downloaded or stored locally on a hard drive or optical disk. In at least one embodiment, a transmission mechanism such as data streaming can be used to transfer this content from server 620, or user database 636, to client device 602. In at least one embodiment, at least a portion of this content can be obtained, enhanced, and/or streamed from another source, such as a third party service 660 or other client device 650, that may also include a content application 662 for generating (e.g., using a generative AI), enhancing, or providing content. In at least one embodiment, portions of this functionality can be performed using multiple computing devices, or multiple processors within one or more computing devices, such as may include a combination of CPUs and GPUs.


In this example, these client devices can include any appropriate computing devices, as may include a desktop computer, notebook computer, set-top box, streaming device, gaming console, smartphone, tablet computer, VR headset, AR goggles, wearable computer, or a smart television. Each client device can submit a request across at least one wired or wireless network, as may include the Internet, an Ethernet, a local area network (LAN), or a cellular network, among other such options. In this example, these requests can be submitted to an address associated with a cloud provider, who may operate or control one or more electronic resources in a cloud provider environment, such as may Include a data center or server farm. In at least one embodiment, the request may be received or processed by at least one edge server, that sits on a network edge and is outside at least one security layer associated with the cloud provider environment. In this way, latency can be reduced by enabling the client devices to interact with servers that are in closer proximity, while also improving security of resources in the cloud provider environment.


In at least one embodiment, such a system can be used for performing graphical rendering operations. In other embodiments, such a system can be used for other purposes, such as for providing image or video content to test or validate autonomous machine applications, or for performing deep learning operations. In at least one embodiment, such a system can be implemented using an edge device, or may incorporate one or more Virtual Machines (VMs), and/or one or more generative AI neural networks or large language models (LLMs). In at least one embodiment, such a system can be implemented at least partially in a data center or at least partially using cloud computing resources.

In at least one embodiment, development, publishing, and/or storing may be performed using a software development kit (SDK) associated with a system (e.g., to ensure that an application and/or container developed is compliant with or compatible with a system). In at least one embodiment, an application that is developed may be tested locally (e.g., at a first facility, on data from a first facility) with an SDK which may support at least some of services 1320 as a system (e.g., system 1200 of FIG. 12). In at least one embodiment, because DICOM objects may contain anywhere from one to hundreds of images or other data types, and due to a variation in data, a developer may be responsible for managing (e.g., setting constructs for, building pre-processing into an application, etc.) extraction and preparation of incoming data. In at least one embodiment, once validated by system 1300 (e.g., for accuracy), an application may be available in a container registry for selection and/or implementation by a user to perform one or more processing tasks with respect to data at a facility (e.g., a second facility) of a user.


In at least one embodiment, developers may then share applications or containers through a network for access and use by users of a system (e.g., system 1300 of FIG. 13). In at least one embodiment, completed and validated applications or containers may be stored in a container registry and associated machine learning models may be stored in model registry 1324. In at least one embodiment, a requesting entity—who provides an inference or image processing request—may browse a container registry and/or model registry 1324 for an application, container, dataset, machine learning model, etc., select a desired combination of elements for inclusion in data processing pipeline, and submit an imaging processing request. In at least one embodiment, a request may include input data (and associated patient data, in some examples) that is necessary to perform a request, and/or may include a selection of application(s) and/or machine learning models to be executed in processing a request. In at least one embodiment, a request may then be passed to one or more components of deployment system 1306 (e.g., a cloud) to perform processing of data processing pipeline.

In at least one embodiment, services 1320 may include compute services, artificial intelligence (AI) services, visualization services, and/or other service types. In at least one embodiment, services 1320 may provide functionality that is common to one or more applications in software 1318, so functionality may be abstracted to a service that may be called upon or leveraged by applications. In at least one embodiment, functionality provided by services 1320 may run dynamically and more efficiently, while also scaling well by allowing applications to process data in parallel (e.g., using a parallel computing platform 1230 (FIG. 12)). In at least one embodiment, rather than each application that shares a same functionality offered by a service 1320 being required to have a respective instance of service 1320, service 1320 may be shared between and among various applications. In at least one embodiment, services may include an inference server or engine that may be used for executing detection or segmentation tasks, as non-limiting examples. In at least one embodiment, a model training service may be included that may provide machine learning model training and/or retraining capabilities.

In at least one embodiment, a visualization service may be used that may add image rendering effects—such as ray-tracing, rasterization, denoising, sharpening, etc.—to add realism to two-dimensional (2D) and/or three-dimensional (3D) models. In at least one embodiment, virtual instrument services may be included that provide for beam-forming, segmentation, inferencing, imaging, and/or support for other applications within pipelines of virtual instruments.


In at least one embodiment, where a service 1320 includes an AI service (e.g., an inference service), one or more machine learning models may be executed by calling upon (e.g., as an API call) an inference service (e.g., an inference server) to execute machine learning model(s), or processing thereof, as part of application execution. In at least one embodiment, where another application includes one or more machine learning models for segmentation tasks, an application may call upon an inference service to execute machine learning models for performing one or more of processing operations associated with segmentation tasks. In at least one embodiment, software 1318 implementing advanced processing and inferencing pipeline that includes segmentation application and anomaly detection application may be streamlined because each application may call upon a same inference service to perform one or more inferencing tasks.


In at least one embodiment, hardware 1322 may include GPUs, CPUs, graphics cards, an AI/deep learning system (e.g., an AI supercomputer, such as NVIDIA's DGX), a cloud platform, or a combination thereof.

In at least one embodiment, use of GPU processing may be implemented for processing locally (e.g., at facility 1302), within an AI/deep learning system, in a cloud system, and/or in other processing components of deployment system 1306 to improve efficiency, accuracy, and efficacy of image processing and generation. In at least one embodiment, software 1318 and/or services 1320 may be optimized for GPU processing with respect to deep learning, machine learning, and/or high-performance computing, as non-limiting examples. In at least one embodiment, at least some of computing environment of deployment system 1306 and/or training system 1304 may be executed in a datacenter one or more supercomputers or high performance computing systems, with GPU optimized software (e.g., hardware and software combination of NVIDIA's DGX System).

In at least one embodiment, any combination of tasks within training system 1304 may be used depending on what is required for each respective machine learning model. In at least one embodiment, one or more of machine learning models may already be trained and ready for deployment so machine learning models may not undergo any processing by training system 1304, and may be implemented by deployment system 1306.


In at least one embodiment, output model(s) 1316 and/or pre-trained model(s) 1406 may include any types of machine learning models depending on implementation or embodiment.

In at least one embodiment, ground truth data may be synthetically produced (e.g., generated from computer models or renderings), real produced (e.g., designed and produced from real-world data), machine-automated (e.g., using feature analysis and learning to extract features from data and then generate labels), human annotated (e.g., labeler, or annotation expert, defines location of labels), and/or a combination thereof. In at least one embodiment, for each instance of imaging data 1308 (or other data type used by machine learning models), there may be corresponding ground truth data generated by training system 1304. In at least one embodiment, AI-assisted annotation may be performed as part of deployment pipelines 1410; either in addition to, or in lieu of AI-assisted annotation included in training pipelines 1404. In at least one embodiment, system 1400 may include a multi-layer platform that may include a software layer (e.g., software 1318) of diagnostic applications (or other application types) that may perform one or more medical imaging and diagnostic functions. In at least one embodiment, system 1400 may be communicatively coupled to (e.g., via encrypted links) PACS server networks of one or more facilities. In at least one embodiment, system 1400 may be configured to access and referenced data from PACS servers to perform operations, such as training machine learning models, deploying machine learning models, image processing, inferencing, and/or other operations.


In at least one embodiment, a software layer may be implemented as a secure, encrypted, and/or authenticated API through which applications or containers may be invoked (e.g., called) from an external environment(s) (e.g., facility 1302). In at least one embodiment, applications may then call or execute one or more services 1320 for performing compute, AI, or visualization tasks associated with respective applications, and software 1318 and/or services 1320 may leverage hardware 1322 to perform processing tasks in an effective and efficient manner.


In at least one embodiment, deployment system 1306 may execute deployment pipelines 1410. In at least one embodiment, deployment pipelines 1410 may include any number of applications that may be sequentially, non-sequentially, or otherwise applied to imaging data (and/or other data types) generated by imaging devices, sequencing devices, genomics devices, etc.—including AI-assisted annotation, as described above. In at least one embodiment, as described herein, a deployment pipeline 1410 for an individual device may be referred to as a virtual instrument for a device (e.g., a virtual ultrasound instrument, a virtual CT scan instrument, a virtual sequencing instrument, etc.). In at least one embodiment, for a single device, there may be more than one deployment pipeline 1410 depending on information desired from data generated by a device. In at least one embodiment, where detections of anomalies are desired from an MRI machine, there may be a first deployment pipeline 1410, and where image enhancement is desired from output of an MRI machine, there may be a second deployment pipeline 1410.


In at least one embodiment, an image generation application may include a processing task that includes use of a machine learning model. In at least one embodiment, a user may desire to use their own machine learning model, or to select a machine learning model from model registry 1324. In at least one embodiment, a user may implement their own machine learning model or select a machine learning model for inclusion in an application for performing a processing task. In at least one embodiment, applications may be selectable and customizable, and by defining constructs of applications, deployment and implementation of applications for a particular user are presented as a more seamless user experience. In at least one embodiment, by leveraging other features of system 1400—such as services 1320 and hardware 1322—deployment pipelines 1410 may be even more user friendly, provide for easier integration, and produce more accurate, efficient, and timely results.


In at least one embodiment, deployment system 1306 may include a user interface 1413 (e.g., a graphical user interface, a web interface, etc.) that may be used to select applications for inclusion in deployment pipeline(s) 1410, arrange applications, modify or change applications or parameters or constructs thereof, use and interact with deployment pipeline(s) 1410 during set-up and/or deployment, and/or to otherwise interact with deployment system 1306. In at least one embodiment, although not illustrated with respect to training system 1304, user interface 1414 (or a different user interface) may be used for selecting models for use in deployment system 1306, for selecting models for training, or retraining, in training system 1304, and/or for otherwise interacting with training system 1304.


In at least one embodiment, pipeline manager 1412 may be used, in addition to an application orchestration system 1428, to manage interaction between applications or containers of deployment pipeline(s) 1410 and services 1320 and/or hardware 1322. In at least one embodiment, pipeline manager 1412 may be configured to facilitate interactions from application to application, from application to service 1320, and/or from application or service to hardware 1322. In at least one embodiment, although illustrated as included in software 1318, this is not intended to be limiting, and in some examples pipeline manager 1412 may be included in services 1320. In at least one embodiment, application orchestration system 1428 (e.g., Kubernetes, DOCKER, etc.) may include a container orchestration system that may group applications into containers as logical units for coordination, management, scaling, and deployment. In at least one embodiment, by associating applications from deployment pipeline(s) 1410 (e.g., a reconstruction application, a segmentation application, etc.) with individual containers, each application may execute in a self-contained environment (e.g., at a kernel level) to increase speed and efficiency.


In at least one embodiment, each application and/or container (or image thereof) may be individually developed, modified, and deployed (e.g., a first user or developer may develop, modify, and deploy a first application and a second user or developer may develop, modify, and deploy a second application separate from a first user or developer), which may allow for focus on, and attention to, a task of a single application and/or container(s) without being hindered by tasks of another application(s) or container(s). In at least one embodiment, communication, and cooperation between different containers or applications may be aided by pipeline manager 1412 and application orchestration system 1428. In at least one embodiment, so long as an expected input and/or output of each container or application is known by a system (e.g., based on constructs of applications or containers), application orchestration system 1428 and/or pipeline manager 1412 may facilitate communication among and between, and sharing of resources among and between, each of applications or containers. In at least one embodiment, because one or more of applications or containers in deployment pipeline(s) 1410 may share same services and resources, application orchestration system 1428 may orchestrate, load balance, and determine sharing of services or resources between and among various applications or containers. In at least one embodiment, a scheduler may be used to track resource requirements of applications or containers, current usage or planned usage of these resources, and resource availability. In at least one embodiment, a scheduler may thus allocate resources to different applications and distribute resources between and among applications in view of requirements and availability of a system. In some examples, a scheduler (and/or other component of application orchestration system 1428) may determine resource availability and distribution based on constraints imposed on a system (e.g., user constraints), such as quality of service (QoS), urgency of need for data outputs (e.g., to determine whether to execute real-time processing or delayed processing), etc.


In at least one embodiment, services 1320 leveraged by and shared by applications or containers in deployment system 1306 may include compute services 1416, AI services 1418, visualization services 1420, and/or other service types. In at least one embodiment, applications may call (e.g., execute) one or more of services 1320 to perform processing operations for an application. In at least one embodiment, compute services 1416 may be leveraged by applications to perform super-computing or other high-performance computing (HPC) tasks. In at least one embodiment, compute service(s) 1416 may be leveraged to perform parallel processing (e.g., using a parallel computing platform 1430) for processing data through one or more of applications and/or one or more tasks of a single application, substantially simultaneously. In at least one embodiment, parallel computing platform 1430 (e.g., NVIDIA's CUDA) may enable general purpose computing on GPUs (GPGPU) (e.g., GPUs 1422). In at least one embodiment, a software layer of parallel computing platform 1430 may provide access to virtual instruction sets and parallel computational elements of GPUs, for execution of compute kernels. In at least one embodiment, parallel computing platform 1430 may include memory and, in some embodiments, a memory may be shared between and among multiple containers, and/or between and among different processing tasks within a single container. In at least one embodiment, inter-process communication (IPC) calls may be generated for multiple containers and/or for multiple processes within a container to use same data from a shared segment of memory of parallel computing platform 1430 (e.g., where multiple different stages of an application or multiple applications are processing same information). In at least one embodiment, rather than making a copy of data and moving data to different locations in memory (e.g., a read/write operation), same data in same location of a memory may be used for any number of processing tasks (e.g., at a same time, at different times, etc.). In at least one embodiment, as data is used to generate new data as a result of processing, this information of a new location of data may be stored and shared between various applications. In at least one embodiment, location of data and a location of updated or modified data may be part of a definition of how a payload is understood within containers.


In at least one embodiment, AI services 1418 may be leveraged to perform inferencing services for executing machine learning model(s) associated with applications (e.g., tasked with performing one or more processing tasks of an application). In at least one embodiment, AI services 1418 may leverage AI system 1424 to execute machine learning model(s) (e.g., neural networks, such as CNNs) for segmentation, reconstruction, object detection, feature detection, classification, and/or other inferencing tasks. In at least one embodiment, applications of deployment pipeline(s) 1410 may use one or more of output models 1316 from training system 1304 and/or other models of applications to perform inference on imaging data. In at least one embodiment, two or more examples of inferencing using application orchestration system 1428 (e.g., a scheduler) may be available. In at least one embodiment, a first category may include a high priority/low latency path that may achieve higher service level agreements, such as for performing inference on urgent requests during an emergency, or for a radiologist during diagnosis. In at least one embodiment, a second category may include a standard priority path that may be used for requests that may be non-urgent or where analysis may be performed at a later time. In at least one embodiment, application orchestration system 1428 may distribute resources (e.g., services 1320 and/or hardware 1322) based on priority paths for different inferencing tasks of AI services 1418.


In at least one embodiment, shared storage may be mounted to AI services 1418 within system 1400. In at least one embodiment, shared storage may operate as a cache (or other storage device type) and may be used to process inference requests from applications. In at least one embodiment, when an inference request is submitted, a request may be received by a set of API instances of deployment system 1306, and one or more instances may be selected (e.g., for best fit, for load balancing, etc.) to process a request. In at least one embodiment, to process a request, a request may be entered into a database, a machine learning model may be located from model registry 1324 if not already in a cache, a validation step may ensure appropriate machine learning model is loaded into a cache (e.g., shared storage), and/or a copy of a model may be saved to a cache. In at least one embodiment, a scheduler (e.g., of pipeline manager 1412) may be used to launch an application that is referenced in a request if an application is not already running or if there are not enough instances of an application. In at least one embodiment, if an inference server is not already launched to execute a model, an inference server may be launched. Any number of inference servers may be launched per model. In at least one embodiment, in a pull model, in which inference servers are clustered, models may be cached whenever load balancing is advantageous. In at least one embodiment, inference servers may be statically loaded in corresponding, distributed servers.


In at least one embodiment, inferencing may be performed using an inference server that runs in a container. In at least one embodiment, an instance of an inference server may be associated with a model (and optionally a plurality of versions of a model). In at least one embodiment, if an instance of an inference server does not exist when a request to perform inference on a model is received, a new instance may be loaded. In at least one embodiment, when starting an inference server, a model may be passed to an inference server such that a same container may be used to serve different models so long as inference server is running as a different instance.


In at least one embodiment, during application execution, an inference request for a given application may be received, and a container (e.g., hosting an instance of an inference server) may be loaded (if not already), and a start procedure may be called. In at least one embodiment, pre-processing logic in a container may load, decode, and/or perform any additional pre-processing on incoming data (e.g., using a CPU(s) and/or GPU(s)). In at least one embodiment, once data is prepared for inference, a container may perform inference as necessary on data. In at least one embodiment, this may include a single inference call on one image (e.g., a hand X-ray), or may require inference on hundreds of images (e.g., a chest CT). In at least one embodiment, an application may summarize results before completing, which may include, without limitation, a single confidence score, pixel level-segmentation, voxel-level segmentation, generating a visualization, or generating text to summarize findings. In at least one embodiment, different models or applications may be assigned different priorities. For example, some models may have a real-time (TAT <1 min) priority while others may have lower priority (e.g., TAT <10 min). In at least one embodiment, model execution times may be measured from requesting institution or entity and may include partner network traversal time, as well as execution on an inference service.


In at least one embodiment, transfer of requests between services 1320 and inference applications may be hidden behind a software development kit (SDK), and robust transport may be provide through a queue. In at least one embodiment, a request will be placed in a queue via an API for an individual application/tenant ID combination and an SDK will pull a request from a queue and give a request to an application. In at least one embodiment, a name of a queue may be provided in an environment from where an SDK will pick it up. In at least one embodiment, asynchronous communication through a queue may be useful as it may allow any instance of an application to pick up work as it becomes available. Results may be transferred back through a queue, to ensure no data is lost. In at least one embodiment, queues may also provide an ability to segment work, as highest priority work may go to a queue with most instances of an application connected to it, while lowest priority work may go to a queue with a single instance connected to it that processes tasks in an order received. In at least one embodiment, an application may run on a GPU-accelerated instance generated in cloud 1426, and an inference service may perform inferencing on a GPU.


In at least one embodiment, visualization services 1420 may be leveraged to generate visualizations for viewing outputs of applications and/or deployment pipeline(s) 1410. In at least one embodiment, GPUs 1422 may be leveraged by visualization services 1420 to generate visualizations. In at least one embodiment, rendering effects, such as ray-tracing, may be implemented by visualization services 1420 to generate higher quality visualizations. In at least one embodiment, visualizations may include, without limitation, 2D image renderings, 3D volume renderings, 3D volume reconstruction, 2D tomographic slices, virtual reality displays, augmented reality displays, etc. In at least one embodiment, virtualized environments may be used to generate a virtual interactive display or environment (e.g., a virtual environment) for interaction by users of a system (e.g., doctors, nurses, radiologists, etc.). In at least one embodiment, visualization services 1420 may include an internal visualizer, cinematics, and/or other rendering or image processing capabilities or functionality (e.g., ray tracing, rasterization, internal optics, etc.).


In at least one embodiment, hardware 1322 may include GPUs 1422, AI system 1424, cloud 1426, and/or any other hardware used for executing training system 1304 and/or deployment system 1306. In at least one embodiment, GPUs 1422 (e.g., NVIDIA's TESLA and/or QUADRO GPUs) may include any number of GPUs that may be used for executing processing tasks of compute services 1416, AI services 1418, visualization services 1420, other services, and/or any of features or functionality of software 1318. For example, with respect to AI services 1418, GPUs 1422 may be used to perform pre-processing on imaging data (or other data types used by machine learning models), post-processing on outputs of machine learning models, and/or to perform inferencing (e.g., to execute machine learning models). In at least one embodiment, cloud 1426, AI system 1424, and/or other components of system 1400 may use GPUs 1422. In at least one embodiment, cloud 1426 may include a GPU-optimized platform for deep learning tasks. In at least one embodiment, AI system 1424 may use GPUs, and cloud 1426—or at least a portion tasked with deep learning or inferencing—may be executed using one or more AI systems 1424. As such, although hardware 1322 is illustrated as discrete components, this is not intended to be limiting, and any components of hardware 1322 may be combined with, or leveraged by, any other components of hardware 1322.


In at least one embodiment, AI system 1424 may include a purpose-built computing system (e.g., a super-computer or an HPC) configured for inferencing, deep learning, machine learning, and/or other artificial intelligence tasks. In at least one embodiment, AI system 1424 (e.g., NVIDIA's DGX) may include GPU-optimized software (e.g., a software stack) that may be executed using a plurality of GPUs 1422, in addition to CPUs, RAM, storage, and/or other components, features, or functionality. In at least one embodiment, one or more AI systems 1424 may be implemented in cloud 1426 (e.g., in a data center) for performing some or all of AI-based processing tasks of system 1400.


In at least one embodiment, cloud 1426 may include a GPU-accelerated infrastructure (e.g., NVIDIA's NGC) that may provide a GPU-optimized platform for executing processing tasks of system 1400. In at least one embodiment, cloud 1426 may include an AI system(s) 1424 for performing one or more of AI-based tasks of system 1400 (e.g., as a hardware abstraction and scaling platform). In at least one embodiment, cloud 1426 may integrate with application orchestration system 1428 leveraging multiple GPUs to enable seamless scaling and load balancing between and among applications and services 1320.

In at least one embodiment, pre-trained model may not be optimized for generating accurate results on customer dataset 1506 of a facility of a user (e.g., based on patient diversity, demographics, types of medical imaging devices used, etc.). In at least one embodiment, prior to deploying a pre-trained model into a deployment pipeline for use with an application(s), pre-trained model may be updated, retrained, and/or fine-tuned for use at a respective facility.


In at least one embodiment, a user may select pre-trained model that is to be updated, retrained, and/or fine-tuned, and this pre-trained model may be referred to as initial model 1504 for a training system within process 1500. In at least one embodiment, a customer dataset 1506 (e.g., imaging data, genomics data, sequencing data, or other data types generated by devices at a facility) may be used to perform model training (which may include, without limitation, transfer learning) on initial model 1504 to generate refined model 1512. In at least one embodiment, ground truth data corresponding to customer dataset 1506 may be generated by training system 1304. In at least one embodiment, ground truth data may be generated, at least in part, by clinicians, scientists, doctors, practitioners, at a facility.


In at least one embodiment, AI-assisted annotation may be used in some examples to generate ground truth data. In at least one embodiment, AI-assisted annotation (e.g., implemented using an AI-assisted annotation SDK) may leverage machine learning models (e.g., neural networks) to generate suggested or predicted ground truth data for a customer dataset. In at least one embodiment, a user may use annotation tools within a user interface (a graphical user interface (GUI)) on a computing device.


In at least one embodiment, user 1510 may interact with a GUI via computing device 1508 to edit or fine-tune (auto)annotations. In at least one embodiment, a polygon editing feature may be used to move vertices of a polygon to more accurate or fine-tuned locations.


In at least one embodiment, once customer dataset 1506 has associated ground truth data, ground truth data (e.g., from AI-assisted annotation, manual labeling, etc.) may be used by during model training to generate refined model 1512. In at least one embodiment, customer dataset 1506 may be applied to initial model 1504 any number of times, and ground truth data may be used to update parameters of initial model 1504 until an acceptable level of accuracy is attained for refined model 1512. In at least one embodiment, once refined model 1512 is generated, refined model 1512 may be deployed within one or more deployment pipelines at a facility for performing one or more processing tasks with respect to medical imaging data.

FIG. 15B is an example illustration of a client-server architecture 1532 to enhance annotation tools with pre-trained annotation models, in accordance with at least one embodiment. In at least one embodiment, AI-assisted annotation tools 1536 may be instantiated based on a client-server architecture 1532. In at least one embodiment, annotation tools 1536 in imaging applications may aid radiologists, for example, identify organs and abnormalities. In at least one embodiment, imaging applications may include software tools that help user 1510 to identify, as a non-limiting example, a few extreme points on a particular organ of interest in raw images 1534 (e.g., in a 3D MRI or CT scan) and receive auto-annotated results for all 2D slices of a particular organ. In at least one embodiment, results may be stored in a data store as training data 1538 and used as (for example and without limitation) ground truth data for training. In at least one embodiment, when computing device 1508 sends extreme points for AI-assisted annotation, a deep learning model, for example, may receive this data as input and return inference results of a segmented organ or abnormality. In at least one embodiment, pre-instantiated annotation tools, such as AI-Assisted Annotation Tool 1536B in FIG. 15B, may be enhanced by making API calls (e.g., API Call 1544) to a server, such as an Annotation Assistant Server 1540 that may include a set of pre-trained models 1542 stored in an annotation model registry, for example. In at least one embodiment, an annotation model registry may store pre-trained models 1542 (e.g., machine learning models, such as deep learning models) that are pre-trained to perform AI-assisted annotation on a particular organ or abnormality. These models may be further updated by using training pipelines. In at least one embodiment, pre-installed annotation tools may be improved over time as new labeled data is added.

Other variations are within spirit of present disclosure. Thus, while disclosed techniques are susceptible to various modifications and alternative constructions, certain illustrated embodiments thereof are shown in drawings and have been described above in detail. It should be understood, however, that there is no intention to limit disclosure to specific form or forms disclosed, but on contrary, intention is to cover all modifications, alternative constructions, and equivalents falling within spirit and scope of disclosure, as defined in appended claims.


Use of terms “a” and “an” and “the” and similar referents in context of describing disclosed embodiments (especially in context of following claims) are to be construed to cover both singular and plural, unless otherwise indicated herein or clearly contradicted by context, and not as a definition of a term. Terms “comprising,” “having,” “including,” and “containing” are to be construed as open-ended terms (meaning “including, but not limited to,”) unless otherwise noted. Term “connected,” when unmodified and referring to physical connections, is to be construed as partly or wholly contained within, attached to, or joined together, even if there is something intervening. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within range, unless otherwise indicated herein and each separate value is incorporated into specification as if it were individually recited herein. Use of term “set” (e.g., “a set of items”) or “subset,” unless otherwise noted or contradicted by context, is to be construed as a nonempty collection comprising one or more members. Further, unless otherwise noted or contradicted by context, term “subset” of a corresponding set does not necessarily denote a proper subset of corresponding set, but subset and corresponding set may be equal.


Conjunctive language, such as phrases of form “at least one of A, B, and C,” or “at least one of A, B and C,” unless specifically stated otherwise or otherwise clearly contradicted by context, is otherwise understood with context as used in general to present that an item, term, etc., may be either A or B or C, or any nonempty subset of set of A and B and C. For instance, in illustrative example of a set having three members, conjunctive phrases “at least one of A, B, and C” and “at least one of A, B and C” refer to any of following sets: {A}, {B}, {C}, {A, B}, {A, C}, {B, C}, {A, B, C}. Thus, such conjunctive language is not generally intended to imply that certain embodiments require at least one of A, at least one of B, and at least one of C each to be present. In addition, unless otherwise noted or contradicted by context, term “plurality” indicates a state of being plural (e.g., “a plurality of items” indicates multiple items). A plurality is at least two items, but can be more when so indicated either explicitly or by context. Further, unless stated otherwise or otherwise clear from context, phrase “based on” means “based at least in part on” and not “based solely on.”


Operations of processes described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. In at least one embodiment, a process such as those processes described herein (or variations and/or combinations thereof) is performed under control of one or more computer systems configured with executable instructions and is implemented as code (e.g., executable instructions, one or more computer programs or one or more applications) executing collectively on one or more processors, by hardware or combinations thereof. In at least one embodiment, code is stored on a computer-readable storage medium, for example, in form of a computer program comprising a plurality of instructions executable by one or more processors. In at least one embodiment, a computer-readable storage medium is a non-transitory computer-readable storage medium that excludes transitory signals (e.g., a propagating transient electric or electromagnetic transmission) but includes non-transitory data storage circuitry (e.g., buffers, cache, and queues) within transceivers of transitory signals. In at least one embodiment, code (e.g., executable code or source code) is stored on a set of one or more non-transitory computer-readable storage media having stored thereon executable instructions (or other memory to store executable instructions) that, when executed (i.e., as a result of being executed) by one or more processors of a computer system, cause computer system to perform operations described herein. A set of non-transitory computer-readable storage media, in at least one embodiment, comprises multiple non-transitory computer-readable storage media and one or more of individual non-transitory storage media of multiple non-transitory computer-readable storage media lack all of code while multiple non-transitory computer-readable storage media collectively store all of code. In at least one embodiment, executable instructions are executed such that different instructions are executed by different processors—for example, a non-transitory computer-readable storage medium store instructions and a main central processing unit (“CPU”) executes some of instructions while a graphics processing unit (“GPU”) executes other instructions. In at least one embodiment, different components of a computer system have separate processors and different processors execute different subsets of instructions.


Accordingly, in at least one embodiment, computer systems are configured to implement one or more services that singly or collectively perform operations of processes described herein and such computer systems are configured with applicable hardware and/or software that enable performance of operations. Further, a computer system that implements at least one embodiment of present disclosure is a single device and, in another embodiment, is a distributed computer system comprising multiple devices that operate differently such that distributed computer system performs operations described herein and such that a single device does not perform all operations.


Use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate embodiments of disclosure and does not pose a limitation on scope of disclosure unless otherwise claimed. No language in specification should be construed as indicating any non-claimed element as essential to practice of disclosure.


All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.


In description and claims, terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms may be not intended as synonyms for each other. Rather, in particular examples, “connected” or “coupled” may be used to indicate that two or more elements are in direct or indirect physical or electrical contact with each other. “Coupled” may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other.


Unless specifically stated otherwise, it may be appreciated that throughout specification terms such as “processing,” “computing,” “calculating,” “determining,” or like, refer to action and/or processes of a computer or computing system, or similar electronic computing device, that manipulate and/or transform data represented as physical, such as electronic, quantities within computing system's registers and/or memories into other data similarly represented as physical quantities within computing system's memories, registers or other such information storage, transmission or display devices.


In a similar manner, term “processor” may refer to any device or portion of a device that processes electronic data from registers and/or memory and transform that electronic data into other electronic data that may be stored in registers and/or memory. As non-limiting examples, “processor” may be a CPU or a GPU. A “computing platform” may comprise one or more processors. As used herein, “software” processes may include, for example, software and/or hardware entities that perform work over time, such as tasks, threads, and intelligent agents. Also, each process may refer to multiple processes, for carrying out instructions in sequence or in parallel, continuously or intermittently. Terms “system” and “method” are used herein interchangeably insofar as system may embody one or more methods and methods may be considered a system.


In present document, references may be made to obtaining, acquiring, receiving, or inputting analog or digital data into a subsystem, computer system, or computer-implemented machine. Obtaining, acquiring, receiving, or inputting analog and digital data can be accomplished in a variety of ways such as by receiving data as a parameter of a function call or a call to an application programming interface. In some implementations, process of obtaining, acquiring, receiving, or inputting analog or digital data can be accomplished by transferring data via a serial or parallel interface. In another implementation, process of obtaining, acquiring, receiving, or inputting analog or digital data can be accomplished by transferring data via a computer network from providing entity to acquiring entity. References may also be made to providing, outputting, transmitting, sending, or presenting analog or digital data. In various examples, process of providing, outputting, transmitting, sending, or presenting analog or digital data can be accomplished by transferring data as an input or output parameter of a function call, a parameter of an application programming interface or interprocess communication mechanism.


Although discussion above sets forth example implementations of described techniques, other architectures may be used to implement described functionality, and are intended to be within scope of this disclosure. Furthermore, although specific distributions of responsibilities are defined above for purposes of discussion, various functions and responsibilities might be distributed and divided in different ways, depending on circumstances.


Furthermore, although subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that subject matter claimed in appended claims is not necessarily limited to specific features or acts described. Rather, specific features and acts are disclosed as exemplary forms of implementing the claims.
