Abstract

The present invention provides a management method and system for traffic forwarding in an SDN network. The method includes receiving a request from a first switch to apply for a forwarding flow table for traffic; calculating the forwarding path of the traffic according to the request, and generating the traffic forwarding paths respectively A MAC switching flow table corresponding to the switch on the forwarding path, wherein the MAC switching flow table is used to instruct the corresponding switch to forward the traffic; and the MAC switching flow table is delivered to the switch on the corresponding path. Through the solution of the present invention, the problem of low traffic forwarding efficiency caused by the need to process a large number of flow tables in the SDN switch in the prior art is solved, and the number of flow tables that actually need to be delivered to the SDN switch can be greatly reduced, thereby alleviating The management pressure of the SDN switch improves the efficiency of traffic forwarding.

Description

technical field [0001] The present invention relates to the traffic forwarding aspect of a software defined network (Software Defined Network, SDN), and in particular to a management method for traffic forwarding in an SDN network. Background technique [0002] In the Open Flow-based SDN architecture, Open Flow realizes flexible control of network traffic by separating the control plane of network equipment from the data plane. The control plane of the entire network is centrally managed and controlled by a device called "Controller". for network deployment. [0003] The switch on the data forwarding plane interacts with the controller through the Open Flow protocol and is controlled by it. The forwarding of data traffic is realized by the way that the controller sends the forwarding flow table to the SDN switch. Different traffic requires different flow tables to manage the forwarding rules. [0004] When traffic is forwarded and exchanged in the SDN network, it enters t...
