Example Embodiment

[0058] The solution of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0059] In an embodiment of the present invention, BPS (Board Protection Switch, board-level protection switching) protection switching is adopted, that is, the protection of the single board to the single board. When the Ethernet link or hardware of the first single board fails, it cannot work normally. Or when it is not in place, the second board will replace the first board to work to ensure that services are not damaged.

[0060] When using BPS protection, the relationship between protection and protected is established between the two boards, that is, the protection group. As long as there is a certain configuration between each two boards, that is, the number and type of interface boards configured on the two boards are the same, and the backplane bandwidth of the first board is not greater than the backplane bandwidth of the second board, ...

Abstract

This invention discloses one Ethernet protection method, which comprises the following steps: establishing protection relationship between first and second single boards and in normal situation for support business by first one; when first board end interface cannot work for normal and the second board is moved in, restoring second terminal data receive function and using linkage status control mechanism to trigger part end interface and to switch business of first board to second board. This invention uses linkage status mechanism to control terminal status and to control end work status or non work status.

Description

technical field [0001] The invention relates to the communication field, in particular to an Ethernet protection method and device. Background technique [0002] In the transmission system, the SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy) protection scheme is relatively complete, but the effective Ethernet access protection is less. At present, there are mainly two ways to realize Ethernet access protection, namely inter-board LAG (Link Aggregation Group, Link Aggregation Group) protocol and TPS (Tributary Protection Switching, tributary protection switching). [0003] Existing technology 1 adopts the inter-board LAG protocol mode, runs the complete LACP protocol (Link Aggregation Control Protocol, Link Aggregation Control Protocol) on the main board and the standby board, and realizes the acquisition of port and link status information and the selection of port status, etc. ; Then the configuration status information is synchronized between the main b...
