Abstract
Embodiments of the present invention provide a protection switching method, comprises: determining that the bandwidth of at least one of the transmission paths changes; obtaining a final path bandwidth combination according to the bandwidth of the transmission path whose bandwidth changes, wherein the final path bandwidth combination is formed by bandwidths of the at least two transmission paths after the bandwidth of at least one transmission path changes; querying the stored mapping relationship between the path bandwidth combination and the channel allocation policy according to the final path bandwidth combination, and determining the channel allocation policy corresponding to the final path bandwidth combination; and performing channel switching according to the channel allocation policy corresponding to the final path bandwidth combination.
