Problems solved by technology

In order to realize the communication between the SDN switch and the SDN controller, it is necessary to build an independent control network based on the TCP / IP protocol outside the OpenFlow business network. question
Especially for wide-area networks with a wide geographical area, the additional construction and maintenance of the control network requires a lot of cost, which brings great resistance to the application of OpenFlow technology

Abstract

The invention discloses a communication method, a software defined network SDN switch and a communication system, and relates to the field of communication. The control system deployment cost of SDN equipment based on OpenFlow in the wide area network environment deployment process can be lowered. The communication method is applied to an SDN based on the OpenFlow, an SDN control network comprises the SDN switch, an operator wireless exit gateway, a wireless convergence gateway and an SDN controller, the SDN switch is connected to an operator wireless network served by the operator wireless exit gateway through a wireless communication module, and the wireless convergence gateway is respectively connected to the wireless exit gateway of the operator wireless network and the SDN controller through a wired network. The communication method comprises the step that the SDN switch is in communication with the SDN controller through the operator wireless network and the operator wireless exit gateway. The communication method is mainly used for the achievement process of the SDN control network based on the OpenFlow.

Description

technical field [0001] The present invention relates to the communication field, in particular to an OpenFlow-based communication method, a Software Defined Network (Software Defined Network, SDN) switch and a communication system. Background technique [0002] In the field of communication, an OpenFlow-based SDN technology is proposed. The core idea of ​​this technology is to use a general "data flow table" for data exchange. Routing and switching information in the network can be represented as data flow, which is stored in the data flow table. Each data flow entry in the data flow table can be used to describe forwarding rules, data operations, and data status. [0003] From the perspective of network architecture, the SDN based on the OpenFlow protocol consists of an OpenFlow switch (OpenFlow Switch) and an OpenFlow controller (OpenFlow Controller). The OpenFlow switch and the OpenFlow controller can also be called SDN switches and SDN controllers. The SDN switch is res...
