Embodiment Construction

[0032] The present invention is different from the MAC address learning performed by the traditional Ethernet switching equipment according to the MAC address+VLAN mode. The present invention performs MAC address learning and aging according to the MAC address+EVC-ID (Ethernet virtual connection number), that is, depends on the MAC address The corresponding relationship between the address and the EVC-ID performs learning and aging of the MAC address respectively. Specifically, if the MAC address of the current message is a new MAC address relative to the table entry in the MAC address table, the learning of the MAC address is carried out; when there is a matching EVC-ID in the MAC address table, the The MAC address aging count corresponding to the EVC-ID is updated (restored to the maximum value).

[0033] Traditional Ethernet bridges will only start one timer when aging the MAC address, instead of starting multiple timers according to EVC. When traversing the MAC address tab...

Abstract

The invention discloses an Ethernet virtual connection field aging medium access control address method, comprising: receiving messages and extracting medium visiting control MAC address carried by the messages and Ethernet virtual connecting number EVC-ID; aging the MAC address corresponding to the EVC-ID if an EVC-ID which is matched with the EVC-ID exists in a MAC address table when information of a timer carrying the EVC-IC is received. List items of the MAC address table comprise the corresponding MAC address and the EVC-ID. The method solves the problem that different businesses requirethe MAC address management differences and simultaneously improves the aging efficiency.

Description

technical field [0001] The invention relates to a method for aging a MAC address according to a flow domain, in particular to a method for aging a Media Access Control (MAC, Media Access Control) address in an Ethernet Virtual Connection (EVC, Ethernet Virtual Connection) domain. Background technique [0002] MEF (Metro Ethernet Forum) is a non-profit organization that focuses on solving Ethernet technology. Its main goal is to define a carrier-class Ethernet architecture and widely apply Ethernet technology as a switching technology and transmission technology to metropolitan area networks. building. It defines three layers of applications: transport layer, Ethernet service layer, and application service layer. The Ethernet service layer is used to implement the traditional Ethernet MAC (Media Access Control, Media Access Control) layer function. The basic principle still follows the characteristics of the Ethernet bridge. The automatic learning function of the source MAC...
