Description

Resource management method, device and system for network equipment

Technical field

The present application relates to the field of data communications, such as resource management methods, devices, and systems related to network devices.

Background technique

The Internet Engineering Task Force (IETF) proposes the concept of Open I2RS (I2RS: Interface to the Routing System), and hopes to solve the traditional network equipment to SDN through the interface of the open control routing system in the control plane. Software Defined Network, software-defined network) The problem of orderly evolution.

The core idea of the I2RS system is to open a new interface to communicate with the external control terminal based on the routing and forwarding system of the traditional network device. The external control terminal (Client) knows the resources, routing configuration, traffic statistics and other information of multiple network devices. The entire network topology map is learned, and the routing status and policies are dynamically sent to multiple devices. It can be seen that I2RS extends the structure and functions of routing and forwarding used in traditional network equipment, and expands and enriches the functions on the basis of this, laying a foundation for the programmability of network equipment. Innovation provides a strong guarantee.

However, the same as the traditional configuration management idea, the I2RS architecture system has not provided a clear component for resource management. The way the I2RS system external control terminal learns the network device resources is still lagging and single. For example, after the external control terminal establishes communication with the network device, the network device resource information cannot be immediately known; when the external control terminal actively initiates the query, the external control terminal can only query the resource information based on the service, and lacks the unified control of the resource; the network device resource occurs. When the network device changes, the network device only reports the event notification based on the service to the external control terminal, which is disadvantageous for the external control terminal to learn the entire network resource information. Therefore, how to realize the overall control of network equipment resources is an urgent problem to be solved.

Therefore, another embodiment of the present invention adopts a simple manner, in which the network control terminal periodically obtains the resource index number from the network device, and determines whether the resource value of the network device has changed according to whether the same device resource index number is consistent: The resource index of the same device is the same, indicating that the resources of the network device have not changed. The resource information saved locally by the network control terminal is the current device resource information. If the information is inconsistent, the network device resources have changed. The saved resource information is to be updated, and then the current device resource information can be obtained by querying the <get> operation mode shown in FIG.

The network control terminal is connected to the network device. When the connection is interrupted for some reasons, such as network flapping or the user actively disconnects, the network control terminal retains the record of the network device for a period of keep alive. When the network control terminal is connected to the network device again, we determine whether the network control terminal has a record of the network device. If not, it indicates that the new device is accessed, and the network control terminal queries the resource information of the new device through the <get> operation mode; If yes, determine whether the index number of the device in the record is consistent with the resource index number advertised in the hello packet reported by the network device, if the index number of the device in the record is retained and the hello message reported by the network device is advertised.

If the resource index number in the record matches the resource index number in the hello packet, the current resource information of the device is the same. The current resource information of the device, if the resource index number in the record is inconsistent with the resource index number in the hello packet, indicating that the resource information of the network device has changed, the resource information of the network device is obtained by using the process shown in FIG.
