Abstract
In the field of network communications, a protection method for a multi-domain network, wherein the multi-domain network comprises a first domain and a second domain and the two domains are interconnected by node B and C, includes: after failure of a first link between the two nodes is detected, node C disconnects a first protection path with the first domain, connects a first sub-path of the first protection path and a path that is within a second domain to form a new protection path for bearing a service across the multi-domain network, and sending, on the first sub-path, a first failure monitoring message that carries first maintenance information to node A, where the first maintenance information is the same as second maintenance information carried in a second failure monitoring message; the second failure monitoring message is a message that is sent on the first protection path by node B to node A and is used to monitor a failure of the first protection path.
