Description

Resource management method, device and control terminal

Technical field

The present invention relates to the field of communications, and in particular to a resource management method, apparatus, and control terminal.

Background technique

The Internet Engineering Task Force (IETF) proposes the concept of the Interface to the Routing System (I2RS). It is hoped that the traditional network equipment can be solved by the interface of the open routing system on the control plane. An orderly evolution of the Switched Data Network (SDN).

1 is an architectural diagram of an I2RS system according to an embodiment of the present invention. The core idea is to open a new interface to communicate with an external control terminal based on the routing and forwarding system of the conventional network device, and the external control terminal (Client) knows each The resources, routing configuration, and traffic statistics of the network device learn the topology map of the entire network, and then dynamically send routing status and policies to each device. 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 concept, the I2RS architecture system does not provide a clear component for resource management. For the control terminal of the I2RS system, after establishing communication with the device, the device resource information cannot be immediately known; when the control terminal initiates the query actively, The device can only query the resource information based on the service, and lacks the unified management and control of the resource. When the device resource changes, the device only reports the event notification based on the service to the external control terminal. At the same time, due to the lack of a resource negotiation mechanism between the control terminal and the device, when the device resources change, the consistency of the resource data of the control terminal and the device cannot be guaranteed. Therefore, it can be seen that there is a problem in the related art that the control terminal cannot uniformly manage resources in the device.
