Control Device and Control Method in SDN Network

Abstract

A preset flow table matching policy in a switching device is set, a flow table for processing data by a switching device that the data needs to pass through during forwarding and an action that needs to be executed in the flow table are generated according to the matching policy and capability information of the switching device, and the flow table is sent to the switching device that the data needs to pass through during forwarding such that the control device may generate, according to different flow table information of the switching device and with reference to different data forwarding policies, a corresponding flow table to be executed by the switching device, which manages switching devices of different types, and enables a switching device that has multiple flow tables to flexibly implement a data forwarding function in use of a preset policy.
