Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the following detailed description of specific embodiments of the present application is given with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the matters related to the present application are shown in the accompanying drawings. Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently, or at the same time. Furthermore, the order of the operations may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The application provides a network information management method of a backbone network controller, which aims to construct different routing equipment protocols to collect network information of routing equipment and uniformly manage the network information. In order to optimize the network information management effect for the diversity of network information acquisition, the network information based on the segmented routing strategy is acquired and managed, so that the network information management effect is optimized. Compared with the traditional backbone network controller, the network information acquisition method and the system generally only acquire link and flow information in the network in the process of network information acquisition. Network information collection is rarely performed for traffic scheduling based on a segment routing Policy (SR Policy). Only the link and the traffic information are used for network information management, and the backbone network controller is difficult to know the traffic scheduling state of the system based on the segment routing Policy (SR Policy), so that the management effect on the network information is relatively poor. Meanwhile, when the traditional backbone network controller collects network information, because the communication protocols of routing equipment of different manufacturers are different, the collected network information formats are different, and different routing information is difficult to mutually use, so that the whole network information management process is complicated, and the network information management effect is affected. Based on the above, the network information management method of the backbone network controller provided by the embodiment of the application is provided to solve the problem that the network information management of the existing backbone network controller is complicated and single.
Examples:
fig. 1 is a flowchart of a network information management method of a backbone network controller according to an embodiment of the present application, where the network information management method of the backbone network controller provided in the embodiment may be implemented by the backbone network controller, and the backbone network controller may be implemented by software and/or hardware, and may be formed by two or more physical entities or may be formed by one physical entity.
The following description will take a backbone network controller as an example of a main body of a network information management method for executing the backbone network controller. Referring to fig. 1, the network information management method of the backbone network controller specifically includes:
s110, collecting network information of each type of routing equipment by using a collecting tool based on a corresponding protocol, wherein the network information comprises at least one of link topology information, link flow information, flow scheduling state information based on a segmented routing strategy and flow information based on the segmented routing strategy.
When the network information is acquired, link topology information, link flow information, flow scheduling state information based on the segment routing strategy and flow information based on the segment routing strategy are respectively acquired, and on the basis of network link state monitoring, relevant network information of flow scheduling based on the segment routing strategy is acquired, so that a backbone network controller can acquire network flow scheduling conditions, and timely make corresponding adjustment strategies and notifications, and network management effects are optimized while diversity of network information acquisition is improved.
When the network information is acquired, corresponding to different types of routing equipment, a preset acquisition tool with a corresponding protocol is used for acquiring the network information. It will be appreciated that the backbone network contains a plurality of routing devices from different vendors and that the data protocols used by the different types of routing devices may be different. Based on the above, the backbone network controller needs to construct acquisition tools of corresponding protocols in advance so as to acquire various types of network information through various types of acquisition tools.
Specifically, referring to fig. 2, a schematic diagram of a network information management system of a backbone network controller according to an embodiment of the present application is provided. Wherein, this network information management system includes: the routing device comprises a routing device driving layer, a general driving layer, a management layer and an interface layer, wherein the management layer comprises management modules for managing corresponding types of network information, and the interface layer comprises an information inquiry interface and an event notification interface; the routing equipment driving layer is used for collecting network information of each type of routing equipment based on a collection tool of a corresponding protocol, wherein the network information comprises link topology information, link flow information, flow scheduling state information based on a segmented routing strategy and flow information based on the segmented routing strategy; the routing device driving layer comprises routing device driving modules corresponding to different routing devices, such as an H routing device driving module and an A routing device driving module corresponding to different manufacturers in fig. 2; the routing equipment driving layer is in butt joint with the routing equipment based on the different routing equipment driving modules so as to acquire network information based on the acquisition tools of corresponding protocols. The universal driving layer is used for converting the network information into a unified data format and storing the network information into a corresponding management module of the management layer according to the type of the network information; the management layer is used for managing network management services of the corresponding network information based on each management module; the interface layer is used for providing external service inquiry of network information through the information inquiry interface and carrying out network event notification based on the network information through the event notification interface.
The backbone network controller of the embodiment of the application executes the network information management method based on the network information management system. When the routing equipment driving layer is used for collecting network information, a collecting tool of a corresponding protocol is configured in the routing equipment driving layer so as to realize communication with the routing equipment of a corresponding type, and network information collection is further carried out. And collecting network information by using collecting tools of different protocols aiming at routing equipment of different manufacturers. And for the network information collection of each type of routing equipment, the network information collection can be realized by using independent submodules so as to facilitate the system to expand the connection of the routing equipment and the network information collection.
In the process of collecting network information, referring to fig. 3, when collecting a link topology information part, a process of collecting link topology information includes:
s1101, under the condition of collecting link topology information, any routing device is docked based on a link state collection tool, and the link state collection tool customizes a communication protocol in advance so as to be compatible with various types of routing devices;
s1102, receiving the whole network link state information of the routing equipment, determining the link topology information based on the whole network link state information, and synchronizing the whole network link state information by the routing equipment through a link state protocol in advance.
It can be appreciated that the backbone controller needs to know all network nodes and link information between the network nodes, i.e. link topology information, so as to plan traffic according to the link topology information. When the backbone network controller sends the traffic from the source node to the destination node, a reasonable traffic routing path can be planned for the traffic from the source node to the destination node based on the link topology information. For example, referring to fig. 4, in order to plan the shortest path from the a router to the E router, the backbone network controller may calculate that the shortest path is from the link AD0 to the link DE0 by acquiring the full graph link topology information.
Based on the above, the backbone network controller needs to acquire real-time link topology information for subsequent traffic management operations such as traffic path planning. The acquisition scheme of the link topology information mainly enables each routing device in the network to operate a link state protocol, and the link state protocol is used for synchronizing the link state of the whole network to generate link-state database (LSDB) of the whole network. Any routing device and the backbone network controller are then docked by a link state collection tool, for example, any routing device is docked by BGP-LS protocol (border gateway protocol), and the routing device reports the link state information of the entire network collected on the routing device as link topology information.
When the network topology information changes, such as node failure, link interruption and IGP parameter change, the link topology information can be synchronized in real time among all network routing devices through a link state protocol and sent to a backbone network controller in real time through a BGP-LS protocol, so that the backbone network controller can sense the change of the network topology at the first time.
By using the BGP-LS protocol, no matter what link state IGP protocol is used by the underlying network, the protocol can be packed and reported to the backbone network controller according to the standard format of the BGP-LS protocol, thereby shielding the difference of network underlying protocol and even routing equipment manufacturers and realizing wider compatibility of network communication.
Optionally, the embodiment of the application pre-develops the BGP-LS protocol. And the border gateway can be ensured to be successfully connected by configuring the neighbor nodes of the border gateway and the local connection address. And customizing various attributes, and improving the communication compatibility of the backbone network controller and the routing equipment by customizing the communication protocol.
And under the condition of collecting the link traffic information, docking each routing device based on a remote data collection protocol, and collecting the corresponding link traffic information. Since the congestion level is not the same for each link in the actual path rules. The congestion level of a link can be measured by the congestion ratio, which = traffic of the link/bandwidth of the link. The backbone network controller needs to select a proper path according to different link congestion degrees, so that traffic based on a segmented routing strategy is prevented from being scheduled to a severely congested link, and a congestion effect is caused, so that a packet loss condition is caused. Based on this, link traffic information for each link in the network is collected by the backbone network controller.
When collecting link traffic information, the collection tool used is an SNMP (simple network management protocol) client. Firstly, an SNMP (simple network management protocol) client is used for collecting the corresponding relation of the node IP, the interface IP and the interface name of each link. The link traffic information is then collected for the different routing devices using a corresponding remote data collection protocol (telemet protocol) interface. For different types of routing devices, information such as interface flow statistics, CPU (Central processing Unit) or memory data of the devices can be periodically and actively sent to the backbone network controller through a push mode (PushMode). Link traffic information may also be uploaded through the open source GNMI interface. It should be noted that, since a link information (node IP, interface IP) may be collected in the link topology information collection stage, the link information and the currently collected link traffic information are combined, so that the interface traffic may be associated with a link.
Based on the acquisition of the link topology information and the link flow information, the embodiment of the application correspondingly acquires the flow scheduling state information and the scheduled flow information aiming at the flow scheduling condition based on the segment routing strategy in the network. Under the condition of collecting traffic scheduling state information based on the segmented routing strategy, collecting the routing state of each segmented path of the traffic scheduling path and the routing state of the corresponding candidate path, wherein the traffic scheduling path is used for forwarding traffic flow as the traffic scheduling state information based on the segmented routing strategy.
In the network operation process, in order to optimize the transmission and processing of the traffic, the traffic of one or more paths is often required to be forwarded so as to realize traffic scheduling and optimize the network operation. In the traffic forwarding scenario, a segment routing Policy (SR Policy) is used for traffic scheduling. The segment routing policy may configure a plurality of candidate paths (CandidatePath). Each candidate path is a candidate forwarding sub-policy, and there may be multiple segment paths (Segmentlist) under each candidate path for load balancing.
When a candidate path with a high priority fails (meaning that all segmented paths under the candidate path fail). The routing equipment can automatically perform fault switching based on the segmented routing strategy, and switch the traffic path to the candidate path with low priority and normal state. And what the controller needs to collect is the state of the segmented path. Once a segmented path fails, representing that the entire candidate path corresponding to the segmented path has failed, the controller is required to re-program a new path for it. The state of the segmented path and the state collection of the candidate paths are very important here.
When the traffic scheduling state information based on the segmented routing strategy is acquired, the traffic scheduling state information of each routing device is collected by using a BGP-LS protocol acquisition tool corresponding to different types of routing devices or a remote data collection protocol (telemet protocol) through an open source GNMI interface. The BGP-LS protocol is also pre-customized, in which candidate path state attributes, segment information, segment path attributes, etc. are customized. Thus, the collection of the flow scheduling state information of the segment routing strategy is realized.
Under the condition of collecting traffic information based on the segmented routing strategy, link traffic information of each segmented path of the traffic scheduling path is collected as the traffic information based on the segmented routing strategy.
In the traffic forwarding scenario, a segment routing Policy (SR Policy) is adopted to perform traffic scheduling. When the backbone network controller performs traffic scheduling, the backbone network controller needs to avoid a congested link to prevent the congestion and packet loss. The backbone network controller considers the current link flow and the link bandwidth each time when planning a new path based on the segment routing policy, and also the flow of each segment path, so that the flow information based on the segment routing policy needs to be collected.
When the traffic information based on the segmented routing strategy is collected, the link traffic information of each segmented path is collected corresponding to different types of routing equipment. The link traffic information of the segment path can be collected based on a remote data collection protocol (Telemetry protocol) by an open source GNMI interface or a routing device actively through a Push Mode uploading Mode, and the traffic information based on the segment routing strategy can be obtained.
By corresponding to the network information collection of different types of routing equipment, the collection tools of corresponding protocols are adopted to adapt to the routing equipment of different manufacturers, and the compatibility of the network information collection, the stability and the reliability of the network information management are improved.
S120, converting the network information into a unified data format, and storing the unified data format into a corresponding management module according to the type of the network information, wherein the management module is used for managing network management services of the corresponding network information.
Further, based on the various types of network information acquired by the routing equipment driving layer, information conversion is performed through the universal driving layer. The universal driving layer is an intermediate layer between the management layer and the routing device driving layer and is mainly responsible for converting the data format. Because the collected network information is data in a form related to the corresponding type of routing equipment, the data needs to be converted into a uniform data format and stored in a management layer so as to facilitate the management layer to manage and call the network information.
In addition, in one embodiment, the management layer may also generate network request information through the corresponding management module to make information requests to the corresponding network nodes. The universal driving layer converts the network request information of the management module into a request format of a corresponding type of routing equipment communication protocol, and sends the converted network request information to the corresponding type of routing equipment so as to acquire the network information of the corresponding type of routing equipment. The information request actively issued by the upper layer is converted into a request form related to the corresponding routing equipment, so that the request can be transmitted to the routing equipment to acquire the corresponding network information.
S130, notifying network event based on the network information and providing external service inquiry of the network information.
Then, based on the acquired link topology information, link flow information, flow scheduling state information based on the segment routing strategy and flow information based on the segment routing strategy, as shown in fig. 2, a link topology information management module, a link flow information management module, a flow scheduling state information management module based on the segment routing strategy and a flow information management module based on the segment routing strategy are respectively set in a management layer to perform unified management of network information so as to perform execution of network management services such as path planning, flow scheduling and the like based on the acquired network information. And, network information for different ages can also be placed at the management layer for service invocation.
In addition, based on the acquired network information, the embodiment of the application also calls the corresponding network information through the interface layer. As shown in fig. 2, the interface layer is divided into two independent sub-modules, and a query module is mainly responsible for providing a unified data query interface to the outside so as to provide flow of the network information for segment routing or flow query of the link; the other is an event notification module, and the event notification is performed through the event notification module when the backbone network controller needs to be notified in real time for different network information. For example, for the link state change, the link state change is reversely injected into the event notification module observer through the backbone network controller, and if the event notification module pays attention to the change of the network information, the event notification module can notify the observer in real time so as to make corresponding adjustment based on the change of the network information in time and optimize the network management effect.
The method comprises the steps that network information of each type of routing equipment is collected through a collection tool based on a corresponding protocol, wherein the network information comprises at least one of link topology information, link flow information, flow scheduling state information based on a segmented routing strategy and flow information based on the segmented routing strategy; converting the network information into a unified data format, and storing the network information into a corresponding management module according to the type of the network information, wherein the management module is used for managing network management services of the corresponding network information; and carrying out network event notification based on the network information and providing external service inquiry of the network information.

And network service management is performed through the network information based on the segmented routing strategy by the collecting system, so that the diversity of network information acquisition can be improved, the network information management effect is further optimized, and the stability and reliability of network information management are improved.
