AI Technical Summary

Problems solved by technology

This will cause the management VLAN channel to form a loop (near-end access network device→first remote access network device→second remote access network device→third remote access network device→near-end access network device ), resulting in a layer-2 forwarding "storm"

Abstract

A method and system for establishing a management channel, comprising: after a controller establishes a netconf connection with a remote access network device, the controller sends its own Internet Protocol (IP) address and openflow protocol port number to the remote end through the established netconf channel Access network equipment; the remote access network equipment establishes an openflow channel connection with the controller after receiving the IP address of the controller and the port number of the openflow protocol. The embodiment of the present invention reduces the complexity of establishing the management channel and avoids channel loops in the management channel.

Description

Technical field[0001]This article involves but is not limited to software-defined network technology, especially a method and system for establishing management channels.Background technique[0002]With the popularization and application of fifth-generation mobile communication technology (5G) and software-defined networking (SDN) / network function virtualization (NFV), the scale of the transmission bearer network is further expanded, the number of access network equipment is also increasing, and a large number of terminals The deployment of equipment puts forward higher requirements for operation and maintenance. Due to the large number, the access network equipment must have a "plug and play" function to improve the efficiency of network deployment.[0003]Under the SDN architecture, the most commonly used southbound interface protocol between the controller and the access network equipment is the openflow protocol (open flow protocol: the standard used to describe the information used...
