Abstract: A network device serving as a head node on a first path may determine, based on obtained first constraint information, whether the first path meets a constraint condition of a target service, and further determine whether to switch a packet forwarding path from the first path to another path.

Abstract: A communication method implemented by a first network device, the method includes receiving, by the first network device, a first packet. The first packet may include a first segment identifier (SID) and a second SID. Determining, by the first network device whether the first SID is unavailable. If the first SID is unavailable, the first network device obtains the second SID based on the first SID, and updates a destination address in the first packet with the second SID, to generate a second packet.
