Embodiment Construction
[0044] The core of the invention is to realize MPLS bidirectional protection switching based on the APS (automatic protection switching) protocol, thereby providing a feasible technical solution for the protection switching of the MPLS bidirectional data channel.
[0045] The realization method of MPLS bidirectional protection switching of the present invention mainly comprises the following steps:
[0046] First, in the multi-protocol label switching MPLS network, configure bidirectional protection switching policy information for the bidirectional label switching path LSP based on the APS protocol;
[0047] The specific configuration method is as follows: in the MPLS network, determine two (or more than two) bidirectional LSPs, and each bidirectional LSP includes two LSPs with opposite directions; Or configure the corresponding protection switching strategy information at the end point; the protection switching strategy information is specifically: the protection path inform...
