Heterogeneous protocol conversion middleware and method for heterogeneous controller cluster

Abstract

The invention discloses a heterogeneous protocol conversion middleware and method for a heterogeneous controller cluster. The heterogeneous protocol conversion middleware includes a heterogeneous controller information reading module, a topology view aggregation module, a flow table generation module, and a heterogeneous protocol conversion middleware. Instruction issuing module of the structure controller, switch migration module. The steps of the heterogeneous controller cluster method are: the heterogeneous controller information reading module and the heterogeneous controller instruction issuing module encapsulate the northbound interface of the heterogeneous controller; the topology view aggregation module constructs the network topology view of the data plane; The flow table generating module issues the flow table through the instruction issuing module of the heterogeneous controller; the switch migration module migrates the switch of the failed heterogeneous controller. The invention has high reliability and convenience, and can build heterogeneous controller clusters under the large-scale SDN network environment.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a heterogeneous protocol conversion middleware and a method for heterogeneous controller clusters in the technical field of network communication. The present invention builds centralized heterogeneous protocol conversion middleware under the environment of Software Defined Network (SDN), so as to realize the cooperative work among heterogeneous controllers supporting vertical architecture to form a heterogeneous controller cluster. Background technique [0002] The controller is responsible for the centralized control of the entire SDN network. It plays a very important role in grasping the resources of the entire network and improving the delivery quality of network resources. It is the core of the entire SDN network architecture. Once the controller cannot provide effective protection in terms of performance or security, What follows is that the service capability ...
