Claim 12:
13. A controller, comprising:
at least one processor;
one or more memories coupled to the at least one processor and storing instructions, which when by the at least one processor, cause the controller to:
allocate a service label corresponding to a service processing manner of a forwarding equivalence class (FEC) and a path;
establish a mapping relationship between the service label and the service processing manner;
send the service label to a source node of the path to enable the source node to insert the service label to a first packet to obtain a second packet to be forwarded along the path to a destination node, wherein the service label is used to instruct a network node on the path to perform service processing on the second packet according to the service processing manner; and
send the mapping relationship to the destination node, wherein the destination node is enabled to pop the service label from the second packet to obtain the first packet based on the mapping relationship.
