Abstract

The invention provides a SDN isomeric multi-controller cooperation method and system. The invention provides a controller communication protocol referring to the OpenFlow protocol and according to thecharacteristics of the controller communication, therefore, the communication without difference between different controllers is realized, and the problem of expansion and collaboration between isomeric controllers is solved; according to the invention, the user is not required to participate in the east-west extension mechanism of the controller, and the seamless interconnection between the isomeric controllers and the isomorphic controllers is realized; and the invention has universality, and can effectively improve the computing power of the controller and the operation stability of the network.

Description

technical field [0001] The present invention relates to the technical field of communication equipment, in particular to an SDN heterogeneous multi-controller coordination method and system. Background technique [0002] The controller is responsible for the centralized control of the entire SDN (Software Defined Network, software-defined network) network, which plays a very important role in grasping the resources of the entire network and improving the delivery quality of network resources. However, the centralization of control capabilities also makes the controller have greater responsibilities. Once the controller cannot provide effective guarantees in terms of performance or security, the service capability of the entire SDN network will be degraded or even the entire network will be paralyzed. In addition, from the perspective of networking architecture, a single controller cannot deal with SDN network problems spanning multiple regions. Therefore, a distributed clus...
