Problems solved by technology

That is to say, the existing OPENFLOW protocol does not provide specific description and support for the application of logical ports, which leads to the fact that many requirements in the SDN network cannot be realized under the current protocol

Abstract

The present invention proposes an SDN network-based switch port information perception method, device and terminal equipment. Wherein, the method includes: receiving logical port information sent by the switch through a port synchronization message, wherein the logical port information includes: extended field information for accessing the SDN network; sensing the logical port in the switch according to the logical port information, and according to application requirements Control the logical port accordingly. The method realizes the flexible perception and application of the logical port information of the switch by the controller, and has the advantages of simple configuration, convenient transformation and high practicability.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to an SDN network-based switch port information perception method, device and terminal equipment. Background technique [0002] SDN (Software Defined Network, Software Defined Network) is a hot technology in the current communication field. The SDN consists of two parts: C (Controller, controller) on the control plane and SW (Switch, switch) on the forwarding plane. According to the current definition of SDN technology, control commands are issued between the controller and the switch through the OPENFLOW protocol to guide the data flow forwarding on the switch. [0003] At present, according to whether they are compatible with traditional switch processing methods, switches supporting the OPENFLOW protocol can be divided into two types: OPENFLOW-Only and OPENFLOW-Hybrid (hybrid). OPENFLOW-Only switches only support OPENFLOW pipelining. OPENFLOW-Hybrid switch...
