When changes are made in a network, effects of that change may impact a wide range of devices and/or entities on the network. Thus, when a change is made to a particular device or software, expected issues and/or unexpected issues may arise in other parts of the network due to the interacting nature of systems and devices in networking environments. In some cases, effects from such impacts can include, for example, loss of service, failed orders, flow fallout, and/or many other issues. There may not be any way to quickly recover from network-topology-induced faults.
Rolling back all network topology changes to some previous point in time may address the network-topology-induced fault being addressed, but may result in other impacts as a result. Namely, network changes may be made to accommodate new equipment, to address known problems, etc., so restoring a network to some previous state of operations may resurface old problems and/or faults that were addressed previously.
The present disclosure is directed to restoring network configurations using network topology snapshots. A network environment can be monitored by one or more network monitoring devices such as the network monitor. The network monitor can capture one or more network topology snapshots that define and/or describe a topology and/or configuration associated with the network environment at a particular time. According to various embodiments of the concepts and technologies disclosed herein, the network monitor can be configured to capture the network topology snapshots each time a configuration and/or topology associated with the network environment is changed, thereby capturing entities included in the topology of the network environment; one or more connections between the entities; one or more attributes associated with the entities and/or connections; other attributes; combinations thereof; or the like. The network monitor can release the network topology snapshots to the server computer and/or make the network topology snapshots available to one or more requestors such as, for example, the server computer.
The server computer can store copies of the network topology snapshots and/or access and/or use the network topology snapshots to provide functionality as illustrated and described herein for restoring network configurations using the network topology snapshots. According to various embodiments of the concepts and technologies disclosed herein, the server computer can host and/or execute a network management service that can be accessed via a portal, an application programming interface (“API”), or other functionality by a device such as, for example, the computing device. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
Via exchanges of session data between the computing device and the server computer, the user and/or other entity associated with the computing device can submit requests to the server computer; the server computer can receive the requests from the computing device; the server computer can send user interface (“UP”) data to the computing device; the computing device can receive the UI data from the server computer; the server computer can send calculated differences to the computing device; the computing device can receive the calculated differences from the server computer; the computing device can submit one or more selections (or data that describe the selections) to the server computer; the server computer can receive the selections from the computing device; and the devices can exchange other data.

The server computer (e.g., via execution of the network management service) can identify the attributes, entities, and/or connections (configurations) associated with the network environment that are to be restored and generate one or more commands for implementing the restoration of those attributes, entities, and/or connections. The server computer (e.g., via execution of the network management service) can send the commands to an orchestration service or other entity that can implement the configuration restoration at the network environment. As such, a user or other entity can selectively restore network configurations using network topology snapshots.

Referring now to
According to various embodiments, the functionality of the server computer 102 may be provided by one or more server computers, application servers, web servers, desktop computers, other computing systems, and the like. It should be understood that the functionality of the server computer 102 may be provided by a single device, by two or more similar devices, and/or by two or more dissimilar devices. For purposes of describing the concepts and technologies disclosed herein, the server computer 102 is described herein as a server computer. It should be understood that this embodiment is illustrative, and should not be construed as being limiting in any way.
The server computer 102 can execute an operating system (not illustrated in
In particular, the network management service 106 can be configured to receive one or more network topology and/or inventory snapshots (“network topology snapshots”) 108 from one or more network monitoring devices or entities (“network monitor”) 110. According to various embodiments of the concepts and technologies disclosed herein, the network topology snapshots 108 can describe, at a particular time, a network configuration associated with the network environment 112 such as a data center, a private network, a public network, and/or other networks and/or networking environments. As used herein, a “network configuration” can be used to refer to, for example, the topology and attributes of one, more than one, and/or all entities associated with the network environment 112; connections between two or more entities of the network environment 112; attributes associated with the one or more entities and/or connections; other aspects of the network environment 112; combinations thereof; or the like.
In some embodiments of the concepts and technologies disclosed herein, the network monitor 110 can generate the network topology snapshots 108 and transmit the network topology snapshots 108 to the server computer 102. In some other embodiments, the network monitor 110 can generate and store the network topology snapshots 108 and the server computer 102 can request and/or otherwise obtain the network topology snapshots 108. Because the network topology snapshots 108 can be obtained by the server computer 102 in additional and/or alternative manners, it should be understood that these examples are illustrative, and therefore should not be construed as being limiting in any way.
According to some embodiments of the concepts and technologies disclosed herein, the network topology snapshots can include data formatted in the JavaScript Object Notation (“JSON”) format. Other data formats are possible and are contemplated such as, for example, data formatted using the Yet Another Markup Language (“YAML”) format; data formatted using the Protocol Buffers (“Protobuf”) format; data formatted in extensible markup language (“XML”); and/or other data formats. In some embodiments, JSON is the preferred format for the network topology snapshots 108, but this is not necessarily the case in all embodiments. As such, it should be understood that these example formats are illustrative, and therefore should not be construed as being limiting in any way.
As mentioned above, the network topology snapshots 108 can describe one or more configurations and/or topologies associated with the network environment 112. As used herein, a “topology” and/or variants thereof can include an inventory associated with the network environment 112, connections between one or more entities included in the network environment 112, attributes associated with the one or more entities and/or connections of the network environment 112, combinations thereof, or the like. Thus, the network topology snapshots 108 can describe the network environment 112 at a particular time including entities operating in and/or with the network environment 112, connections between the entities operating in and/or with the network environment 112, attributes associated with the entities and/or connections, combinations thereof, or the like. Over time, the entities, connections, and/or attributes associated with the network environment 112 can change. According to various embodiments of the concepts and technologies disclosed herein, the network monitor 110 can be configured to detect any change to the entities, connections, and/or attributes, and to generate a network topology snapshot 108 upon the occurrence of any such change.
As such, it can be appreciated that the network topology snapshots 108 can capture changes to the network environment 112, including times at which each change to the network environment 112 occurred. As such, embodiments of the concepts and technologies disclosed herein can use the network topology snapshots 108 to track changes to the network environment 112 and, in some embodiments, times at which these changes were made. Attribute changes can include, for example, ownership associated with an entity (e.g., hardware, software, connections, and/or combinations thereof) in the network environment 112; a location of the entity; an operating state of the entity; a version (e.g., model number, software version, or the like) associated with the entity; one or more other entities with which the entity communicates; sub-entities and/or components of the entity; combinations thereof; or the like. Because other types of entities are contemplated and are possible, it should be understood that these examples are illustrative, and therefore should not be construed as being limiting in any way.
In various embodiments of the concepts and technologies disclosed herein, the server computer 102 can obtain the network topology snapshots 108 and store the network topology snapshots 108 locally and/or remotely. The server computer 102 can be configured to store a network topology snapshot 108 when a network topology snapshot 108 is released by the network monitor 110 (if released by the network monitor 110); when a change is made to the network environment 112; when a network topology snapshot 108 is sent to the server computer 102; and/or at other times. In the illustrated embodiment, the server computer 102 can be configured to store each network topology snapshot 108 that is released by the network monitor 110 and the network monitor 110 can be configured to generate and release a network topology snapshot 108 each time any entity, connection between entities, and/or attribute associated with the entities and/or connections of the network environment 112 is changed. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
According to various embodiments of the concepts and technologies disclosed herein, the network management service 106 can be configured to obtain and/or store the network topology snapshots 108 and to enable interactions with the network topology snapshots 108 by one or more users or other entities. In the illustrated embodiment, a user or other entity can access the server computer 102, e.g., via a portal, an API, or other functionality (“portal”) 114 using a computing device 116 such as a desktop computer, smartphone, laptop computer, other computing device, or the like. In the illustrated embodiment, the server computer 102 can be configured to expose its functionality to a user or other entity such as the computing device 116 via a web portal or login. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
The computing device 116 can execute an operating system 118 and one or more application programs 120 such as, for example, a web browser, a standalone application, other application, combinations thereof, or the like. The operating system 118 can include a computer program that can control the operation of the computing device 116 and the application programs 120 can include various executable programs that can be configured to execute on top of the operating system 118 to support interactions between the computing device 116 and the server computer 102. In various embodiments of the concepts and technologies disclosed herein, the application programs 120 can include a web browser for accessing and/or interacting with the server computer 102 via the portal 114. Because the computing device 116 can interact with the server computer 102 in additional and/or alternative manners, it should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
In the illustrated embodiment, the server computer 102 can be configured (e.g., via execution of the network management service 106) to generate, and/or to exchange with the computing device 116, session data 122. The session data 122 can also be generated by the computing device 116. Thus, it can be appreciated that the session data 122 can correspond to data exchanged between the server computer 102 and the computing device 116 during a session. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
The session data 122 can include, for example, data associated with a network management session. According to various embodiments, the session data 122 can include any data exchanged between the computing device 116 and the server computer 102 during the session such as one or more requests, UI data, one or more calculated differences (between network topologies as indicated by the network topology snapshots 108 for example), one or more selections (e.g., selections and/or user input entered via a portal, command prompt, the UI, or the like), other data (e.g., session setup communications, passwords, logins, other data, or the like), combinations thereof, or the like.
The requests can include, for example, a request from the computing device 116 for information relating to topologies of the network environment 112, service calls or the like for invoking the network management service 106, a request to calculate differences between two or more network topology snapshots 108, and/or other requests. In some embodiments, the requests can be sent to the server computer 102 by the computing device 116 via one or more network connections such as via the network 104 and/or the network environment 112. In some other embodiments, the requests can be “sent” to the server computer 102 via the portal 114 or other functionality, for example via a web page or the like, which can be provided to the computing device 116 via the session data 122 in some embodiments. Because the requests can be received by the server computer 102 in additional and/or alternative manners, it should be understood that these examples are illustrative, and therefore should not be construed as being limiting in any way.
The UI data can include, for example, display data that, when executed by the application programs 120, can cause the computing device 116 to present a web page, application, or other display via which a user or other entity can view and/or interact with network configurations and/or topologies associated with the network environment 112, differences between two or more network configurations and/or topologies associated with the network environment 112, and/or attributes associated with the configurations and/or topologies associated with the network environment 112.
The calculated differences can include one or more differences between two network configurations and/or topologies. Thus, the differences can indicate one or more attributes, entities, and/or connections of the network environment 112 that have changed over some time (e.g., between times associated with a first network topology snapshot 108 and a second network topology snapshot 108). In some embodiments, as noted above, the network topology snapshots 108 can correspond to JSON files and the differences can be calculated by comparing the network topology snapshots 108. For example, one contemplated embodiment of the concepts and technologies disclosed herein can calculate the differences by executing the following code or other code that may be similar to the following request:
In the above example bulk single-transaction API request and response sample payloads, node creates (e.g., put action lines) and updates (e.g., patch action lines) are shown. It should be understood that the concepts and technologies disclosed herein also support delete actions that can show node removal. In response to the above request, the following response can be generated, in the example embodiment:
In another embodiment, a request that includes delete lines can include the following example request:
And a response to the above request can include the following response:
Because differences between two or more configurations and/or topologies associated with the network environment 112 can be determined in additional and/or alternative manners, it should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
The selections can include, for example, one or more instances of user input and/or selections. For example, the selections can correspond to interactions the user has with one or more UIs to indicate, for example, one or more entities, connections, and/or attributes to restore for a network configuration and/or topology. In some embodiments, the selections can include Boolean indicators. For example, each attribute that can be restored can have an associated check box or other selector for a user or other entity to indicate if the associated attribute is to be rolled back, reverted, and/or restored. Thus, the selections can correspond to the selection or deselection of the associated check boxes or the like. Because the selections of the user or other entity can be indicated in additional and/or alternative manners, it should be understood that these examples are illustrative, and therefore should not be construed as being limiting in any way.
The other data can include, for example, session setup data, passwords, IDs, location information, user information, organization information, encrypted information, encryption/decryption key information, other information, combinations thereof, or the like. Thus, it should be understood that the other data can include almost any information that may be used in accordance with the various embodiments of the concepts and technologies disclosed herein.
Via the exchange of session data 122 between the computing device 116 and the server computer 102, one or more network topology snapshots 108 can be viewed and two or more network topology snapshots 108 can be compared to one another; the network environment 112 can be restored to include aspects of one or more previous network topologies associated with the network environment 112; and/or other operations can be performed with respect to topologies of the network environment 112. If a selection (of the session data 122) indicates that a configuration (e.g., a topology and/or aspects of a topology) of the network environment 112 is or are to be restored, the network management service 106 can be configured to perform one or more operations for implementing the requested restoration.
In particular, the network management service 106 can be configured to analyze the one or more selections to detect one or more aspects of the topology of the network environment 112 that are to be restored and to generate one or more instances of executable code (“commands”) 124 that, when executed by an entity associated with the network environment 112 such as an orchestration service 126, will cause the orchestration service 126 to restore the configuration of the network environment 112 as requested. In various embodiments of the concepts and technologies disclosed herein, the selections can indicate that attributes associated with one or more entities are to be restored.
In various embodiments of the concepts and technologies disclosed herein, a user is not required to restore a configuration of the network environment 112 in whole (e.g., to restore all entities and connections associated with a particular network topology snapshot 108 to their state at a time associated with the network topology snapshot 108). Rather, embodiments of the concepts and technologies disclosed herein enable a user or other entity to specify one, more than one, or all entities and/or connections associated with a particular network topology snapshot 108 that are to be restored to a previous state. Thus, the concepts and technologies disclosed herein can restore attributes, entities, connections, and/or other aspects of a network configuration without restoring all attributes, entities, connections, and/or other aspects of the network configuration. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
The server computer 102 can generate the commands 124 and transmit the commands 124 directed to the orchestration service 126 and/or one or more other entities. The orchestration service 126 or other entity can alter one or more entities, connections, and/or attributes associated with the network environment 112 to restore the network environment 112 as indicated in the session data 122. Thus, a user or other entity can interact with the server computer 102 to compare present and previous network configurations, to identify differences therebetween, and/or to selectively revert one or more aspects of the network configurations to a previous state in some embodiments. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
In practice, a network environment 112 can be monitored by one or more network monitoring devices such as the network monitor 110. The network monitor 110 can capture one or more network topology snapshots 108 that define and/or describe a topology and/or configuration associated with the network environment 112 at a particular time. According to various embodiments of the concepts and technologies disclosed herein, the network monitor 110 can be configured to capture the network topology snapshots 108 each time a configuration and/or topology associated with the network environment 112 is changed, thereby capturing entities included in the topology of the network environment 112; one or more connections between the entities; one or more attributes associated with the entities and/or connections; other attributes; combinations thereof; or the like. The network monitor 110 can release the network topology snapshots 108 to the server computer 102 and/or make the network topology snapshots 108 available to one or more requestors such as, for example, the server computer 102.
The server computer 102 can store copies of the network topology snapshots 108 and/or access and/or use the network topology snapshots 108 to provide functionality as illustrated and described herein for restoring network configurations using the network topology snapshots 108. According to various embodiments of the concepts and technologies disclosed herein, the server computer 102 can host and/or execute a network management service 106 that can be accessed via a portal, API, or other functionality by a device such as, for example, the computing device 116. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
Via exchanges of session data 122 between the computing device 116 and the server computer 102, the user and/or other entity associated with the computing device 116 can submit requests to the server computer 102; the server computer 102 can receive the requests from the computing device 116; the server computer 102 can send UI data to the computing device 116; the computing device 116 can receive the UI data from the server computer 102; the server computer 102 can send calculated differences to the computing device 116; the computing device 116 can receive the calculated differences from the server computer 102; the computing device 116 can submit one or more selections (or data that describe the selections) to the server computer 102; the server computer 102 can receive the selections from the computing device 116; and the devices can exchange other data. By way of the session data 122, the computing device 116 can indicate one or more configurations to restore at the network environment 112.
The server computer 102 (e.g., via execution of the network management service 106) can identify the attributes, entities, and/or connections (configurations) associated with the network environment 112 that are to be restored and generate one or more commands 124 for implementing the restoration of those attributes, entities, and/or connections. The server computer 102 (e.g., via execution of the network management service 106) can send the commands 124 to an orchestration service 126 or other entity that can implement the configuration restoration at the network environment 112. As such, a user or other entity can selectively restore network configurations using network topology snapshots 108.
Turning now to
It also should be understood that the methods disclosed herein can be ended at any time and need not be performed in its entirety. Some or all operations of the methods, and/or substantially equivalent operations, can be performed by execution of computer-readable instructions included on a computer storage media, as defined herein. The term “computer-readable instructions,” and variants thereof, as used herein, is used expansively to include routines, applications, application modules, program modules, programs, components, data structures, algorithms, and the like. Computer-readable instructions can be implemented on various system configurations including single-processor or multiprocessor systems, minicomputers, mainframe computers, personal computers, hand-held computing devices, microprocessor-based, programmable consumer electronics, combinations thereof, and the like.
Thus, it should be appreciated that the logical operations described herein are implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as states, operations, structural devices, acts, or modules. These states, operations, structural devices, acts, and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof. As used herein, the phrase “cause a processor to perform operations” and variants thereof is used to refer to causing a processor of a computing system or device, such as the computing device 116 or the server computer 102, to perform one or more operations and/or causing the processor to direct other components of the computing system or device to perform one or more of the operations.
For purposes of illustrating and describing the concepts of the present disclosure, the method 200 is described herein as being performed by the server computer 102 via execution of one or more software modules such as, for example, the network management service 106. It should be understood that additional and/or alternative devices and/or network nodes can provide the functionality described herein via execution of one or more modules, applications, and/or other software including, but not limited to, the network management service 106. Thus, the illustrated embodiments are illustrative, and should not be viewed as being limiting in any way.
The method 200 begins at operation 202. At operation 202, the server computer 102 can receive a request to compare network topology snapshots such as the network topology snapshots 108. In some embodiments, the request received in operation 202 can correspond to a command, a service call, or an explicit request, any and/or all of which may be created by the computing device 116 via interactions with the server computer 102 via the portal 114 and/or other interfaces. In some embodiments, the computing device 116 may connect to the server computer 102 (e.g., via accessing the portal 114 using a web browser, application, or other functionality such as the application programs 120) and that connection may be understood by the server computer 102 as corresponding to a request to compare network topology snapshots 108. Because the request received (or detected) in operation 202 can be received in additional and/or alternative manners, it should be understood that these examples are illustrative, and therefore should not be construed as being limiting in any way.
From operation 202, the method 200 can proceed to operation 204. At operation 204, the server computer 102 can obtain two or more network topology snapshots 108. In some embodiments, the server computer 102 can store the network topology snapshots 108 and can retrieve two or more network topology snapshots 108 from a local storage device. In some other embodiments, the network topology snapshots 108 may be stored at a remote data storage device or entity, and operation 204 therefore can correspond to the server computer 102 obtaining the network topology snapshots 108 from another device. Because the network topology snapshots 108 can be obtained or retrieved in various matters, it should be understood that these examples are illustrative, and therefore should not be construed as being limiting in any way.
In some embodiments, the server computer 102 can obtain two or more network topology snapshots 108 for operation 204, with the server computer 102 obtaining the most current network topology snapshot 108 and a previous network topology snapshot 108 (the version before a change or changes that resulted in a most current network topology snapshot 108). In some other embodiments, the server computer 102 can be configured to access all network topology snapshots for a network environment 112 and/or portion thereof (e.g., a subnet). As such, it should be understood that operation 204 can correspond to the server computer 102 obtaining two or more network topology snapshots 108. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
From operation 204, the method 200 can proceed to operation 206. At operation 206, the server computer 102 can calculate differences between the two or more network topology snapshots 108 obtained in operation 204. In some example embodiments, the network topology snapshots 108 can include JSON files (as explained above with reference to
In some embodiments, the server computer 102 can determine each entity added to the network environment 112 over time (e.g., from one or more network topology snapshots 108 and the most current network topology snapshot 108); each entity removed from the network environment 112 over time (e.g., from one or more network topology snapshots 108 and the most current network topology snapshot 108); each connection added, modified, and/or deleted between two or more entities in the network environment 112 over time (e.g., from one or more network topology snapshots 108 and the most current network topology snapshot 108); each entity attribute and/or connection attribute added, changed, and/or deleted with respect to entities and/or connections in the network environment 112 over time (e.g., from one or more network topology snapshots 108 and the most current network topology snapshot 108); other changes; combinations thereof; or the like. Thus, operation 206 can include the comparison of the two or more network topology snapshots 108 and storing or caching those differences for presentation to a user or other entity.
From operation 206, the method 200 can proceed to operation 208. At operation 208, the server computer 102 can present or provide the differences between the network topology snapshots 108. In some embodiments, the differences can be presented in one or more UIs (e.g., the UIs illustrated and described below with reference to
In some embodiments, the presentation and/or providing of the differences in operation 208 includes presenting a representation (e.g., a graph, a list, or the like) of a current topology of the network environment 112 (or portion of the network environment 112) and showing all changes to the network environment 112 or portion thereof over time as captured by all of the available network topology snapshots 108 associated with the network environment 112 and/or portion thereof. In any event, the presentation of the differences can include presenting options for a user or other entity to select one or more entity, connection, and/or attribute that is to be changed to a previous operating state. Example UIs for enabling these and/or other features as illustrated and described herein will be illustrated and described below with reference to
From operation 208, the method 200 can proceed to operation 210. At operation 210, the server computer 102 can determine if a request to restore is received. In the context of operation 210, the request to restore can include a request to restore a previous configuration and/or operating state associated with one or more entities and/or connections of the network environment 112. A user or other entity can select any number of entities, connections, and/or attributes that are to be restored from one or more previous times and is not required in embodiments of the concepts and technologies disclosed herein to restore operating state and/or configuration of all entities, connections, and/or attributes of the network environment 112.
For example, a network environment 112 or portion thereof may have two entities and one connection therebetween at a first time. These entities and connections can be represented by a first network topology snapshot 108. The network environment 112 or portion thereof can have four entities and six connections between these entities at a second time. These entities and connections can be represented by a second network topology snapshot 108. The network environment 112 or portion thereof can have three entities and three connections between these entities at a third time. These entities and connections can be represented by a third network topology snapshot 108.
A user or other entity may be enabled to selectively restore a connection and/or entity that has been removed between two or more times (e.g., restore an entity removed and/or remove a connection added, etc.). Any change to any entity, connection, or attribute can be selectively (and independently) reverted to any time according to various embodiments of the concepts and technologies disclosed herein without restoring other operating states, configurations, and/or attributes associated with entities and/or connections at that time. Thus, embodiments of the concepts and technologies disclosed herein can provide very specific restoration that can be limited in scope by users and/or other entities, and operation 210 can correspond to determining if a user or other entity has indicated that one or more configuration changes are to be reverted, in some embodiments. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
If the server computer 102 determines, in operation 210, that a request to restore has not been received, the method 200 can proceed to operation 212. The method 200 can end at operation 212. If the server computer 102 determines, in operation 210, that a request to restore has been received, flow can proceed with the operations of the method 300 shown in
Turning now to
The method 300 begins at operation 302. At operation 302, the server computer 102 can identify or determine a configuration change that is to be reverted. As explained herein, a user or other entity may be presented with one or more UIs for identifying one or more configuration changes that are to be reverted, so operation 302 can correspond to the server computer 102 determining if one or more selections received from the computing device 116 (e.g., as the selections included in the session data 122) have been received. Although in some embodiments all configuration changes that are to be reverted can be identified at a single time and/or a single iteration of the session data 122 or other data, the method 300 is illustrated and described with reference to an embodiment in which a single configuration change reversion/restoration is determined to have been requested in operation 302. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
From operation 302, the method 300 can proceed to operation 304. At operation 304, the server computer 102 can identify a restore point (e.g., a point in time, a number of iterations to be reverted, etc.) for the configuration change that is to be reverted as identified in operation 302. It can be appreciated that the user or other entity can provide input and/or selections that can identify one or more changes to configurations, as explained in detail herein. Thus, operation 304 can include the server computer 102 determining that a user or other entity has selected or provided input for designating a restore point associated with the state to which the configuration change is to be reverted. Thus, operation 304 can correspond to the server computer 102 determining, for the one or more configuration reversions to be implemented, a restore point associated with that reversion (e.g., the configuration may have changed three or more times, in which case the server computer 102 can determine which of the two or more previous configurations is to be reapplied and/or reverted to by way of the requested reversion). It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
From operation 304, the method 300 can proceed to operation 306. At operation 306, the server computer 102 can determine if additional configuration changes are to be reverted and/or restored. As noted above, some embodiments of the concepts and technologies disclosed herein can include identifying all configuration changes that are to be reverted at a single time and/or in a single iteration of the session data 122 or other data, in which case operation 306 may include identifying all configuration changes that are to be made. In the illustrated embodiment, in which a single configuration change reversion/restoration is determined to have been requested in operation 302, operation 306 can correspond to determining if any other configuration changes have been requested for reverting. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
If the server computer 102 determines, in operation 306, that additional configuration changes are to be reverted, the method 300 can return to operation 302, and an additional configuration change that is to be reverted can be identified. Operations 302 through 306 can be iterated until the server computer 102 determines, in any iteration of operation 306, that there are no additional configuration changes that are to be reverted.
If the server computer 102 determines, in any iteration of operation 306, that there are no additional configuration changes that are to be reverted, the method 300 can proceed to operation 308. At operation 308, the server computer 102 can output commands 124 for implementing the one or more configuration changes identified over one or more iterations of operations 302-306. Thus, operation 308 can include the server computer 102 generating the commands 124 for implementing the one or more configuration changes, though this is not separately illustrated in
In some embodiments of the concepts and technologies disclosed herein, the generating and/or outputting of the commands 124 can be performed for each configuration change identified (e.g., before the functionality of operation 306), while in some other embodiments such as the example embodiment shown in
From operation 308, the method 300 can proceed to operation 310. At operation 310, the server computer 102 can update the network inventory and/or obtain an updated network topology snapshot 108 that reflects the changes implemented by way of the methods 200, 300. In some embodiments, the network monitor 110 may issue an updated network topology snapshot 108 when any change to the network environment 112 (and/or portion thereof) is detected, as noted above, so operation 310 can correspond to the server computer 102 receiving an updated network topology snapshot 108. In some other embodiments, the server computer 102 can trigger changes to the network topology snapshot 108 and/or trigger delivery of an updated network topology snapshot 108. Because the inventory, topology, and/or configurations associated with the network environment 112 can be updated and/or reflected in additional and/or alternative manners, it should be understood that these examples are illustrative, and therefore should not be construed as being limiting in any way.
From operation 310, the method 300 can proceed to operation 312. The method 300 can end at operation 312.
In particular, according to various embodiments, the computing device 116 can generate the screen display 400A and/or other screen displays in conjunction with and/or based upon interactions with the network management service 106 described herein, which can be configured to render the screen display 400A using data generated at the computing device 116 and/or using data provided by the server computer 102 (e.g., the network management service 106), for example, the session data 122 illustrated and described herein. It should be appreciated that the UI diagram illustrated in
According to various embodiments, the screen display 400A can be presented, for example, when a computing device 116 receives data detailing a comparison of network topology snapshots 108. For example, the screen display 400A can be presented in response to the computing device 116 receiving data from the server computer 102 (e.g., the session data 122) in response to the server computer 102 performing operation 208 of the method 200. Of course, the computing device 116 may present the calculated differences between two or more network topology snapshots 108 at additional and/or alternative times, so it should be understood that the above example is illustrative and therefore should not be construed as being limiting in any way.
The screen display 400A can include various menus and/or menu options (not shown in
As shown in
The configuration comparison window 402 also can include one or more display relationships selectors 412A-B (hereinafter collectively and/or generically referred to as display relationships selectors 412). Selection of one of the display relationships selector 412 can cause the computing device 116 to present a graph and/or other visual representation of the configuration depicted in the associated section (e.g., the display relationships selector 412A can be associated with the historical state section 406 and the display relationships selector 412B can be associated with the current state section 408). Thus, selection of the display relationships selector 412A can cause the computing device 116 to present a graphical representation of the historical state (e.g., previous configuration) associated with the network environment 112 and/or a portion thereof and selection of the display relationships selector 412B can cause the computing device 116 to present a graphical representation of the current state (e.g., current configuration) associated with the network environment 112 and/or a portion thereof. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
As can be seen in the changes section 410, attributes that have been changed between the two or more configurations depicted in the configuration comparison window 402 can include additional information such as, for example, if the entity, connection, and/or attribute has been created, deleted, and/or modified; an entity that made the change; and/or additional and/or alternative information. In some embodiments of the concepts and technologies disclosed herein, each attribute that has been changed can be accompanied, for example, by a checkbox and/or other functionality for selecting or deselecting that entity, connection, and/or attribute (e.g., for selectively indicating which, if any, entities, connections, and/or attributes are to be reverted). It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way. Because additional or alternative controls (e.g., a “revert configuration option”) can be included in the configuration comparison window 402, it should be understood that the example embodiment shown in
The screen display 400B can include various menus and/or menu options (not shown in
The display current configuration window 414 can include a graph or diagram of the current state and/or configuration of the network environment 112 or a portion thereof including one or more entity representations 416 (
The entity representation 416 can identify a particular entity such as a virtual network function, a physical network function, a connection, a piece of hardware, or other asset associated with the network environment 112 and/or a portion thereof. The entity representation 416 can correspond to a UI control that, when selected, can cause the computing device 116 or other device displaying the screen display 400B to generate a flyout or other window for presenting information associated with the entity that corresponds to the entity representation 416 (e.g., name, type of entity, installation date, operating state, attributes, etc.). It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
The activity representations 418 can represent activities that have occurred in association with the entity represented by the entity representation 416. The activity representations 418 can employ color coding in some embodiments, though other indicators (e.g., text indicators, icon changes, etc.) are contemplated. The color coding in the example embodiment shown in
The activities can include attribute changes, entity moves, name changes, ownership changes, and/or other changes, additions, and/or deletions. Thus, it can be appreciated that at least thirteen actions have occurred with respect to the entity represented by the entity representation 416 between some previous time and the current time. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
The inheritance lines 420 can indicate which entity the action representations are associated. In some instances, multiple entities can be represented by the display current configuration window 414, so the activity representations 418 displayed may be associated with multiple entities. Thus, the inheritance lines 420 can indicate which entity the actions are associated with. It should be understood that this example is illustrative, and therefore should not be construed as being limiting in any way.
As shown in
The screen display 400C can include various menus and/or menu options (not shown in
The display historical configuration window 424 can include a graph or diagram of the past state and/or configuration of the network environment 112 or a portion thereof including one or more entity representations 416 (
As can be appreciated with collective reference to
As shown in
The display historical configuration window 424 also can include animation controls 428, which can be used to animate the changes to the configurations illustrated by the display historical configuration window 424. Thus, for example, selection of a “play” button can cause the computing device 116 to animate changes to the configuration of the network environment 112 (or a portion thereof) over time. Other controls can include controls for advancing through network topology snapshots 108, stop controls, fast forward controls, reverse controls, and other controls as generally is understood. Because other controls can be displayed, it should be understood that these examples are illustrative, and therefore should not be construed as being limiting in any way. Also, it should be understood that the example embodiment shown in
