Abstract: This application discloses a packet processing method including: receiving a first packet that includes a DA field and an SRH, where the DA field includes at least one C-SID that is sequentially arranged; determining, depending on whether another C-SID is further included after a first C-SID corresponding to the first node in the at least one C-SID, whether a first processing flavor corresponding to the first C-SID indicates a movement operation or a replacement operation; and if the first processing flavor indicates a movement operation, moving a target field that is after the first C-SID and that is in the DA field, to enable the target field to cover the first C-SID in the DA field; or if the first processing flavor indicates a replacement operation, replacing the first C-SID in the DA field with a second C-SID in the SRH.

Abstract: A packet sending method and device. The first node sets a next-hop of the routing information to a next-hop through which the first node reaches the first route source. The destination address of the routing information is the address prefix. When the second route source is superior to the first route source, the first node switches the next-hop of the routing information to a next-hop through which the first node reaches the second route source. Then, the first node adds, to a target packet, path information of a forwarding path from the first node to the second route source according to the switching operation, where a destination address of the target packet matches the address prefix. Finally, the first node forwards the target packet to the second route source through the forwarding path.
