Title
(EN) Aggregated link switching method and device
(ZH) 聚合链路切换方法及装置
Abstract
(EN)
The invention discloses an aggregated link switching method and an aggregated link switching device. The method comprises the following steps of: configuring a main link and a standby link in a plurality of links to be aggregated; aggregating the plurality of links to be aggregated according to a link aggregation protocol and determining the working state of each link according to a link aggregation result; and detecting a connection failure management protocol for each link in the aggregated links, and judging whether link switching is performed or not according to the working state of a failed link if detecting the failed link. By the method and the device, the reliability of the links can be improved, so that the requirement of carrier-grade time switching is met.
