<p>The invention discloses a method for realizing a bidirectional linear protection switching for a multiplex section. The method includes: after a node device calculates the bridging request with the highest priority in a protection group, it performs bridging and switching for the service corresponding to the bridging request, according to a first decision mode. The invention also discloses the node device including at least one working port and one protection port, wherein the working port and the protection port interact with an automatic protection switching (APS) module and the APS module is set for: performing bridging and switching for the service corresponding to a bridging request, according to the first decision mode, after calculating the bridging request with the highest priority in a protection group. The invention can greatly improve the switch efficiency of the bidirectional 1: N linear protection for a multiplex section.</p> |
