Method and system for preventing address table from being refreshed repeatedly in protection of Ethernet ring

Abstract

The present disclosure discloses a method for preventing repeated updating of an address table in Ethernet ring network protection, including: an Ethernet ring network node sends an Ethernet ring network protection protocol frame and encapsulates its own node information into the Ethernet ring network protection protocol frame; an Ethernet ring network node receives the Ethernet ring network protection protocol frame and matches the node information encapsulated in the received Ethernet ring network protection protocol frame with its own node information; and when the matching is successful, the Ethernet ring network node does not update the address table. The present disclosure further discloses a system for preventing repeated updating of an address table in Ethernet ring network protection. In the system, a matching unit is used for matching the node information encapsulated in the received Ethernet ring network protection protocol frame with the node information of an Ethernet ring network node itself; and when the matching is successful, the Ethernet ring network node does not update the address table. Through the method and system of the disclosure, the problem of repeated updating of an address table in Ethernet ring network protection in the scenario of requesting local protection switching can be solved.

Description

technical field [0001] The invention relates to an Ethernet protection technology, in particular to a method and a system for preventing repeated refreshing of an address table in the protection of an Ethernet ring network. Background technique [0002] With the development of Ethernet in the direction of multi-service bearing, especially some services have higher and higher requirements on network reliability and real-time performance, Ethernet widely adopts ring networking to improve network reliability. And in the protection scheme of this ring networking, it is usually required that the fast protection switching can reach less than 50 ms. Currently, this fast protection switching technology can be implemented based on the G.8032 protocol of the International Telecommunication Union (ITU-T, International Telecommunication Union). [0003] Based on the above-mentioned G.8032 protocol, an automatic protection switching protocol and mechanism are defined for the Ethernet la...
