This disclosure relates to a reconfigurable infrastructure system comprising a networked cloud of edge computing infrastructure, cloud computing infrastructure, at least one virtual appliance, at least one edge device, and at least one medium controller.
New satellite technologies have opened new access to Satellite communication (SATCOM). Recently, capabilities from new High Throughput Satellites have dropped the cost of SATCOM by 4× (from $800 to $200/Mbps/month). Oren “Satellite-Based Cellular Backhaul: Myths and Facts” Gilat Technical White Paper (2018) [Gilate Satellite Networks Ltd.] Additionally, with the deployment of new satellite constellations like OneWeb, Starlink, Telesat, and Kuiper, this cost may further decrease. If the most ambitious plans are realized, up to 50,000 satellites will be in orbit in the next ten years. Daehnick, Klinghoffer, Maritz, and Wiseman, “Large LEO satellite constellations: Will it be different this time?” McKinsey Industry Insights (2020) [McKinsey & Company].
This rapid pace of technology change is a huge deviation from the industry norm, where monolithic purpose-built proprietary hardware and waveforms predominate. These rigid solutions that currently dominate SATCOM ecosystems are not suitable for a rapidly changing environment. “Satellite Ground Network Virtualization” NSR White Paper (2020) [Northern Sky Research]; “United States Space Force Vision for Satellite Communications” Vision Document (2020) [U.S. Space Force]. There exists a need in the art for an integrated, flexible, and adaptable system to maximize the capabilities of SATCOM.

This disclosure provides for a reconfigurable infrastructure system comprising a networked cloud of edge computing infrastructure, cloud computing infrastructure, at least one virtual appliance, at least one edge device, and at least one medium controller.
The inventors surprisingly found that the combination of Software Defined Networking (SDN) and Network Function Virtualization (NFV) technologies can be used to support the deployment of virtual networks using homogenous commodity computing hardware for all network functions. This a departure from having different network functions reside within a single computing system. In one embodiment, network resources can be deployed dynamically with increasing network agility while reducing capital and operating expenses. Network Function Virtualization (NFV) acts as a network architecture that decouples network functions from dedicated hardware through virtualization into an entire class of Virtual Network Functions (VNF), which are chained together, to create communication services. Software Defined Networking (SDN) serves as networking paradigm that decouples decisions from networking infrastructure into a logically centralized controller to determine network management policies and operation. In summary, NFV enables the VNFs, SDN enables the virtualization of the networking interfaces between the VNFs, hypervisors enable the virtualization of hardware resources for SDN and VNFs. Although these elements are useful in assembling virtual networks and network functions there are further challenges in virtualizing accelerated computing resources and access to transmission mediums.
Computing resources have been historically based on Central Processing Units (CPUs) becoming heterogeneous (e.g., relying on other silicon architectures for computing) by leveraging Field Programmable Gate Arrays (FPGAs), Application Specific Integrated Circuits (ASICs), Graphics purpose Processing Units (GPUs), and combinations thereof, for hardware acceleration.
High Performance Computers (HPC), CPU architecture with hardware acceleration is used in the art as part of computing architectures, enabling real time signal processing. In past practices, access to accelerators was established through purpose built hardware designed around the accelerator or integrating acceleration into existing designs. Recently, integration has become easier, where accelerators can be deployed as separate modules into computing architectures, e.g., through PCIe (peripheral component interconnect express) cards in network servers. CPU architectures may provide interfaces to allow for direct programing and easier access to hardware acceleration.
In reference to
As depicted in
In
In the modem architecture shown in
The inventors found that if the modem architecture is modularized, it may be produced at lower costs with greater flexibility for applications.
The inventors surprisingly discovered that if integrated, hardware-based modem architectures are split into baseband modem functions and the analog signal processing (e.g., edge device) components then modularization of signal processing may be achieved.
The baseband modem sends the digital sample interface over a standard interface (e.g., IP, PCIe, InfiniBand) to the analog signal processing (e.g., the Edge Device (ED)), in a practical implementation the ED may be a stand-alone device or a separate PCIe card installed in a server. In a preferred configuration, any baseband modem can send/receive digital sample interface to/from any edge device. The digital sample interface communicates samples and associated frequency context (e.g., center frequency, bandwidth) between the baseband modem and the edge device. Thus, the baseband modem is completely decoupled, where sets of baseband modems and edge devices can be treated as separate resources and commodities. The inventors found that this solved a problem in the computer arts by providing flexibility and adaptability in telecommunications, especially SATCOM, versus the conventional, inflexible, limited, hardware-based systems currently used.
A diagram showing this split is provided in Error! Reference source not found., panel B. The instant disclosure considers pools of HPCs (baseband modems) and edge devices (analog signal processing) forming the basis for medium access resources which, when used in combination of SDN/NFV allow one to begin to deploy virtualized systems and modems. An all-digital, software-only modem is described in U.S. Pat. No. 10,397,038. The inventors surprisingly discovered that the separation between baseband modem and edge devices, and through SDN/NFV networks wireless networks can be completely reconfigurable and now can fully leverage virtualization. In particular, the systems (architecture) and methods described herein provides superior operational capability for of any system that transmits and receives signals over any medium or variety of mediums.
Through SDN/NFV the system and methods described herein provides flexible and agile medium access functions and systems. Medium access functions include communications waveforms, signal collection, or signal generation functions to support medium access systems. Medium access systems include the assembly of network functions together with medium access functions to turn signal collection into information. For example, medium access systems include, but are not limited to, communications applications, like SATCOM, WiFi, or 5G, but can be used for detection and ranging systems (e.g., SONAR, RADAR, LIDAR) and the observation of signals (e.g., lawful intercept, astronomy, sensing). In the event that a better communications waveform or signal collection technique can improve system performance, the medium access function of the medium access system can be replaced with minimal service interruption. In the case of a communications provider, a medium access system can be deployed to observe communications and inject signals for system tests of the communications system. In the most complex systems, a plurality of medium access systems is referred to herein as a medium access network.
The methods and systems described herein have significant benefits for medium access systems which require system upgrades. For SATCOM networks, migration to different satellite constellation, waveform, and frequency can have significant costs associated with acquiring and deploying new equipment and/or reconfiguring old equipment. Cellular networks face similar problems, especially for performing upgrades on thousands of cellular sites for deploying new licenses/waveforms/frequencies. Medium channel assignment is not an isolated problem and is further complicated when a variety of different mediums (e.g., wireless, fiber) and corresponding medium access systems are also considered. For example, if information flow transitions from one medium to another, upgrades on one medium may require cascading upgrades to downstream mediums due to increased volume or quality of information.
The systems and methods described herein provide a system solution that performs physical medium channel assignment, where given set of medium channels, of the same medium, are assigned to a set of different medium access functions to achieve the objectives of the management system. Additionally, the methods and systems described herein provides the medium channel assignment solution for medium access functions/systems/networks with more than one physical medium (e.g., wireless, fiber) are within the same common infrastructure.
The systems and methods described herein provide hardware and virtualized architecture to support fault, performance, configuration, accounting, and security management for array of medium access networks comprised of networks and systems that send or receive a plurality of signals on a plurality of mediums. The systems described herein comprises an ecosystem network and medium access agility that solves current connectivity, accessibility, and cost problems for medium access systems. The systems and methods described herein can be used to deploy a plurality of medium access systems across a plurality of mediums. Additionally, the methods and systems described herein supports reconfigurable medium access systems. The system architecture can become a communications system for a satellite hub, satellite transponder, remote terminal, cellular base station, user terminal, radar, or enterprise wireline network or router. In another embodiment, the system architecture described herein can perform signal collection. Additionally, the system architecture described herein may be configured as a radar system, signal generator, or a combination thereof. In other embodiments, the systems described herein can serve as a radar system, a signal collection platform for lawful intercept, tactical radio, or signal generator system. This flexibility and adaptability of the systems described herein combined with the reduced costs solves problems with the current inflexibility and lack of adaptability in current hardware-based telecommunication systems, including SATCOM systems.
For example, current SATCOM systems have several disadvantages over the systems and methods described herein. Current SATCOM systems are built from purpose-built hardware, software, and firmware, and do not have the level of reconfigurability of the systems and methods described herein. In current practice, purpose-built communications systems may be adaptable from a set of waveforms, which are usually proprietary. Through a combination of proprietary hardware, software, and firmware modem vendors have built walled garden preventing entry from other players to introduce their own waveforms or medium access functions. These walled gardens are an antiquated business model. NFV and SDN networks combined with Software Define Radio (SDR) solutions can be limited to the use of software and CPU architectures. Such approaches are power inefficient and are limited in performance. The systems and methods described herein comprise pooled hardware accelerators, which form heterogeneous computing architectures into the ecosystem architecture. The systems and methods described herein allow for ability to access not only a plurality of transmissions or receptions for a given access medium, but also a plurality of access mediums and management of the physical mediums resources across independent virtualized medium access networks, systems, and functions. Unlike traditional SDN and NFV techniques used in cellular Radio Access Networks (RAN) the systems and methods described herein provide a function known as the Physical Medium Access Manager (PMAM) for the management access resources of a common managed medium, where the medium comprises resources of that specific medium.
The virtual medium access networks and virtual medium access systems described herein are provisioned and deployed through the network configuration portal that provides the operator/customer selections of virtual medium access networks, virtual medium access systems, service level agreement options, and physical medium access resources to deploy or order. In one embodiment, the network configuration portal is a web-based user interface used to configure the virtual wireless network and virtual wireless systems based on this user/customer selection. For example, the systems and methods described herein may present a customer with options for deploying a medium access network like deploying cloud-based computing resources on systems (e.g., Amazon Web Services (AWS), Microsoft Azure, OVH). An advantage over current systems is that the systems and methods described herein allow the user to configure and order their virtual network and systems and order those systems based on the resources available from the hardware infrastructure and the physical medium together.
An advantage over current systems is that the systems and methods described herein are based on a second portal for application developers to add their applications into the ecosystem so they can be deployed by through network configuration portal. The systems and methods described herein can present options within a medium access scenario in business ecosystems of applications, currently unavailable. There are two improved aspects of the medium access scenario the management and allocation of medium resources and the management and allocation of analog signal processing resources (edge devices), and medium controllers as in support of the deployment of those applications. In the systems and methods described herein, the application portal only presents virtual medium access networks/systems that can be deployed based on the available medium access resources. A diagram overviewing the virtual environment of the systems and methods described herein is depicted in
Additionally, the systems and methods described herein comprise virtual appliances, which virtualize key network functions and use hardware accelerator and assigns those resources as necessary to support to the virtual network functions and medium access functions, as needed. Virtual appliances are a flexible hardware container that support heterogeneous computing and flexible functions for signal processing and medium access.
The system described herein may comprise two different components: a hardware architecture and a virtualized architecture. The description that follows begins with the hardware architecture and exemplary virtualized configurations associated with it
In reference to
External networks are other communications networks outside of the networked cloud that also may be connected via MPLS or IP networks. This is set of networks outside that are connected to the networked cloud. POP is the Point of Presence it is the routing to the external networks via IP or MPLS links. Networked Cloud is the sum total network that includes multiple computing cloud systems that are fully connected using software defined networking. The networked cloud also includes systems that reside in computing systems in different geolocations. Edge Computing is additional computing resources that are near or the location of the edge devices or medium controllers. It's assumed that edge computing resources are only CPU based resources. Cloud Computing are additional computing resources that are not at the location of the edge devices or medium controllers. Cloud computing resources may be only CPU based computing resources. Virtual appliance computing device that supports HPC by using a hardware accelerator (FPGA, GPU, DSP) for providing high performance communications. Virtual appliances can live in the cloud location or at the edge. However, in this diagram there is a distinction between CPU and HPC resources for sake of clarity of presentation. Digital sample interface is the specific software defined networked routing that carries digital sample interface signals from the virtual appliances to the edge devices. ED are the Edge Devices used to convert the digital sample interface signals into analog signal MC are the Medium Controllers which translate the analog signals into the signal medium.
This symbol above represents the signal received from or transmitted into the physical medium.
The cloud and edge computing resources may be general computing resources that can be networking and computing resources which can be used to further manage the set of virtual appliances, edge devices (EDs), and mobile communication (MC) resources. The edge and cloud computing resources may comprise virtual appliances. However, there is a distinction of these resources apart from the virtual appliance. There are several reasons for this distinction. First, the hardware acceleration plays a key role in supporting real-time signal processing, which will in turn support medium access functions. Second, the digital sample interface is an underlying resource to support medium access functions. Given these reasons, presentation is easier to consider with virtual appliances as their own distinct units. To this end, the set of virtual appliances can be used to deploy medium access functions intensive computations that require acceleration. The virtual appliance may be a high-performance computer (HPC).
In one embodiment, hypervisors may be deployed across the entire network cloud to support virtualization of the resources across the edge, cloud, and virtual appliances. In another embodiment, the virtualized architecture may be supported by a common Operating System (OS) instead of a hypervisor, which supports multiple logical software containers instead of virtualized hardware. An example of hypervisor architecture with different virtual functions is shown in
In reference to
The bottom layer of
In
The central processing unit (CPU) architecture is shown as a plurality of physical machines and/or virtual appliances, which is compatible with cloud-based infrastructures. While the network cloud supports connection to any device within the cloud, in this embodiment, the digital sample interface is connected with a router. In the systems and methods described herein, Software Defined Networking (SDN) may be used for all routing. For example, ED resources shown in
In reference to
Additionally, the sets of Edge Devices (EDs) may be deployed alongside Medium Controllers (MCs). The EDs are connected via SDN to all the virtual appliances to support the exchange of digital sample interface messages for a plurality of configurations. ED may receive their context information for their received digital sample interface from either a virtualized modem or system/network controller function to coordinate concepts like handoffs and diversity applications. To access the physical medium the medium controller translates output analog signals from the ED into a signal corresponding to the medium (e.g., RF, fiber, sonar, copper, optical). In this configuration, the MC can assume the tasks like amplification, frequency selection, and spatial aspects of the medium (e.g., antenna pointing).
The hardware architecture of the system and methods described herein support a plurality of useful network configurations, where a plurality of virtual appliances can send/receive digital sample interface from a plurality of EDs. Additionally, the system and methods described herein provides a plurality of virtual/container functions that can send/receive digital sample interface from a plurality of EDs.
In reference to
In one embodiment,
In reference to
In reference to
In one exemplary configuration, the systems and methods described herein comprise a single virtual appliance that can deploy a plurality of virtual functions (virtual machines or containers) for transmit or receive tasks, which is referred to herein as virtual medium access functions. In one exemplary configuration, the systems and methods described herein also supports transitions between virtual medium access functions to support reconfiguration and fault management in the network. These connection transitions are depicted in
Additionally, each virtual appliance is not constrained to have the same functions for each virtual medium access functions. For example, one virtual medium access function may be used for spectral analysis while the other may be used for communications, while another may be used for test signals or for signal monitoring. In the systems and methods described herein all of the networking and computing functions can be realized into virtual networks and network functions enabled by technologies such as SDN/NFV. In another embodiment, the systems and methods described herein can be used to send parallel data streams of data by using the same or different waveforms, including similar waveforms.
The virtualized architecture of the systems and methods described herein use the hardware architecture described herein, exemplified in
The virtualized architecture may be logically described in three layers: Infrastructure, Virtual Network Function, and Business Service. The lowest layer is the infrastructure layer, which is the logical association of allocable resources for the virtualized wireless ecosystem architecture. Unlike the standardized NFV architecture (ETSI, “Network Functions Virtualization (NFV) Architectural Framework,” ETS GS NFV 002 V1.1.1, Oct. 2013, [Online]), the system and methods described herein comprise an infrastructure layer comprising two logical inner layers: the physical medium access sublayer and the network function virtualization sublayer. There are a plurality of physical medium access layers, one for each medium, which hold the logical grouping of Physical Medium Resources (PMR) for each specific medium. Each physical medium access layer is to serve an as accounting of the resources for media access and media channel assignment.
The other layer in the infrastructure layer is the network function virtualization infrastructure layer, which is the logical grouping of the virtual network management functions (e.g., Network Function Virtualization (NFV) Manager, physical medium access manager, Service Orchestrator) and virtual network functions. Resources pooled in the network function virtualization layer include CPU, Hardware Acceleration, Edge Devices, Memory (including RAM and disk), and networking. These resources are assigned, through the NFV manager, to the virtual network functions and virtual medium access functions.
The NFV manager in the virtual network function layer is responsible for management of resources in infrastructure layer to deploy the virtual medium access network and systems (e.g., virtual medium access networks/systems). This includes both resources from the network function virtualization infrastructure and physical medium access layers
Additionally, the NFV manager is also responsible for starting up and tearing down the virtual network functions and networks. To manage this virtual network functions resource usage, the NFV manager also determines optimal resource utilization for all the virtual networks and systems. It is important to note that the resources in any infrastructure layer do not need to be in the same physical location. Infrastructure can be on premises, at the edge, or cloud based infrastructure as well as a simplest configuration deployed in a remote location, as exemplified in
The physical medium access manager is responsible for managing the physical medium access layer resources with NFV manager and the virtual medium access networks. The physical medium access resources can be assigned or modified during VNF creation or operation depending on the operation of the ecosystem. For example, in the event fault causes resources to become unavailable, a handoff procedure, and/or any dynamic resource reallocation resources may be reassigned to virtual medium access networks/systems/functions through requests to the physical medium access manager. In another embodiment, the physical medium access manager assigns large allocations of resources, which can be further split into more granular resource allocations by the virtual medium access networks for assignment onto individual systems. For example, the physical medium access manager assigns 100 MHz to of radio spectrum to a virtual medium access network. Then virtual medium access network may evenly divide the spectrum among its virtual medium access systems (e.g., for 10 systems 10 MHz each). In the case of SATCOM system, the physical medium access manager may manage the resources of 5 different satellites each with two different transponders. To access that spectrum there may be a limited number of antennas to control, which may be associated with an ED or the ED may be assigned to operate on the frequencies/antenna. The physical medium access manager initially must be notified of the resource schema and the constraints of granularity for assignment. In general, resources are to be represented widely multidimensional resource blocks and constrained by physical access resources. For example, for SATCOM systems there may be 3 satellites each with 4×150 MHz transponders, but only a single antenna resource or ED that can access them. Management, assignment, and optimization of these physical access resources is the responsibility of the physical medium access manager.
The service orchestrator is responsible for processing orders and translates network configuration order into directions to the NFV manager will create and deploy VNFs. In summary, the service orchestrator assembles and determines the virtual network and needed NFVs based on the customer order. A template database serves a library of all virtual medium access networks and systems, which can be instantiated by the NFV manager. The NFV manager receives the individual commands from the service orchestrator to create each of the virtual network function in the virtual medium access network/system from the service orchestrator based on the templates from the database. The orchestrator does a resource inquiry with the NFV manager, which is then coordinated with the physical medium access manager. In one embodiment, a centralized service orchestrator may also communicate with more than one NFV managers within the network cloud locations to enable reconfiguration in response to changes from the user or resiliency plan. In another embodiment, a distributive service orchestrator model may coordinate resource requests with other service orchestrators in different networks to form a complete network service chain. For example, in a SATCOM system a hub may have its own orchestrator and each individual remote site may also have its own orchestrator. In this way, independent architecture can coordinate reconfigurations to maintain connectivity and interoperability.
To support actual operations, the virtual network function layer has a plurality of virtual medium access networks, which may access a plurality of access mediums. The plurality of virtual medium access network also is connected via a Virtual Network (VN). The set of virtual medium access networks may also be managed by a Network of Network Management System (NoNMS). Each virtual medium access network comprises a plurality of virtual medium access systems. Each virtual medium access system includes an assembly of virtual medium access system functions that when strung together, via a VN, provide functionality for transmission and/or reception of signals from a medium.
In one exemplary configuration, the virtual medium access system described herein may be a communications system. In the example of SATCOM system, the virtual medium access system includes but is not limited to virtualized functions such as: Virtual Modem (VM), Performance Enhancing Proxies (PEP) (e.g., data compression, WAN acceleration), SECurity (e.g., AES encryption), Antenna Control Unit (ACU). The ACU would be an application that would leverage virtual modem data to inform the antenna controller for dish/antenna beam pointing. Stringing together virtualized functions, under common interface standards, different vendors, which called “partners”, can provide wireless system functions which may be selectable by the customer/operating who is deploying the wireless system. In this scenario, the VM will interface with the medium, and therefore is a virtual medium access function. The other functions are referred to generically as the virtual network functions.
Sets of virtual medium access systems may further be connected to network management systems, which provide the network operator a method configuration management of all the virtual wireless systems in a virtual wireless network. Additionally, the virtual medium access network can provide access to a gateway function to allow virtual connections to the PoP. Furthermore, Fault, Configuration, Accounting, Performance, and Security (FCAPS) network functions may be virtualized to provide plurality of specific functions required for the virtual medium access network. These functions may be firewalls, network address translation, network performance analysis functions of key performance indicators, network packet inspection, or fault management functions to direct hand overs to different virtual medium access network or virtual medium access system configurations.
The business service layer contains the functions that primarily interface actors or users of the ecosystem. Actors interface the ecosystem through two different portals: the network configuration portal and the application portal. The network configuration portal is used by ecosystem operators or as a customer interface under a managed services business model. In any case, the actor of this network configuration portal selects and configures the virtual wireless systems they wish to deploy and subsequently the virtual wireless networks. These interactions go through the portal and are submitted to the service orchestrator, which then translates the orders for the NFV manager to create the virtual medium access network(s). Similarly, the application portal presents a point of interaction where ecosystem partners offer VNF(s) or applications to be deployed in virtual medium access networks have a point of entry to upload their application into the ecosystem, which is then presented to actors accessing the network configuration portal.
The final part of the business service layer is the billing and accounts function. The billing and accounts function manage billing and payments for orders and applications. In one case, if a customer is accessing the network configuration portal, the cost of virtual wireless network created will be based on the size of the virtual wireless network, features of the network, VNF used, and duration the virtual medium access network is deployed. After actors use the network configuration portal to deploy a virtual medium access network, the billing and accounts function translates the virtual medium access network into a cost, which may issue a bill or transaction to the actor(s). When applications are used and deployed into networks those actors who pay to use those applications and the actors that upload applications through the application portal are then issued payment through the billing and accounting function. Ecosystem maintenance or service fees are also managed by the billing and accounts and can be issued to actors who order services, provide applications, and manage the ecosystem. In summary, the billing and accounts function manages accounts for virtual wireless network orders, application usage, ecosystem usage, and physical medium resources.

For this example, an instantiated system that is shown in
Another advantage of the system described herein is its interactions with users of the ecosystem. The system and methods described herein in execution may have three primary actors: users, ecosystem provider, and partners. These relationships are analogous to a business model similar to ride sharing, where the users are passengers, the ride sharing company (company and applications) is the ecosystem, and partners are the drivers. In this example, the medium access may be a service, where the hardware infrastructure is owned/managed by the ecosystem provider.
The user interacts with the ecosystem through the network configuration portal by configuring and selecting the virtual medium access functions and virtual network functions that will comprise the virtual medium access system. The user may customize their own system or select from a pre-configured virtual medium access system. Additionally, the user may select additional virtual network functions for the network management system and FCAPS functions to complete the entire selection of the virtual medium access network. After the user has completed selecting and configuring their desired virtual medium access networks, they then can place their “order” and for the ecosystem and the service orchestrator starts the process to instantiate the virtual medium access networks. The billing and accounts systems keeps track of what the user will be billed according to their configuration and time the have their medium access network deployed. Billing and accounts also will bill any fees associated with licensing according to agreements between users, partners, and the ecosystem provider. This is analogous to the ride sharing company collecting fees from customers who connect drivers to riders.
Partners interaction with the ecosystem is similar to users. However, their interactions are based on providing virtual network functions and virtual medium access functions for users. Partners submit their applications into the ecosystem through the application portal. Along with the submission into the ecosystem, a billing agreement for use of their virtual network function or virtual medium access function is also established. The billing agreement includes ecosystem fees provided to the ecosystem provider for each transaction. Additionally, the partner will collect fees when users instantiate their virtual functions. These fees are accounted for in the billing and accounting function in the business service layer.
