Abstract:
1. An automatic protection switching method, comprising: querying, by a network edge node when monitoring that a bandwidth of a first transmission path decreases, a protection switching policy to obtain a priority value corresponding to a decreased bandwidth value or a bandwidth decrease value according to the decrease of the bandwidth, wherein the protection switching policy comprises at least a mapping relationship between the decreased bandwidth value or bandwidth decrease value and the priority value, and comprises a switching rule, and the switching rule comprises indication information of determining service(s) with priority lower than the priority value as service(s) to be switched from the first transmission path to the second transmission path; determining, by the network edge node, the service(s) with priority lower than the priority value as the service(s) to be switched from the first transmission path to the second transmission path; and switching, by the network edge node, the to-be-switched service(s) between the second transmission path and the first transmission path.
