Abstract: A method includes obtaining, by a first network node, a first segment identifier advertisement message, where the first segment identifier advertisement message includes a first segment identifier and a first flag bit, and the first segment identifier is corresponding to a second network node; determining, by the first network node, that the first flag bit indicates that a packet needs to be forwarded through the second network node; and generating, by the first network node, a first packet forwarding path, where the first packet forwarding path includes the second network node.

Abstract: A network performance parameter sending method includes: obtaining, by a first network node, a segment identifier of a second network node in a segment list of a packet, where the second network node is a next-hop segment node of the first network node on a forwarding path of the packet; and adding, by the first network node, a network performance parameter of the first network node to the segment list, and then sending the packet to the second network node. In a process of forwarding the packet by using the segment list in the packet, the first network node uses the segment list to carry the network performance parameter of the network node.

Abstract: A segment routing device receives a first packet from a first network. A first packet header of the first packet includes a segment list. The segment list includes a plurality of sequentially arranged identifiers. The identifiers include a first-type identifier and a plurality of second-type identifiers. Network devices or links identified by the first-type identifier and the second-type identifier are respectively on the first network and a second network. A type of the first network is different from a type of the second network. The segment routing device encapsulates a second packet header for the first packet to form a second packet. The second packet header includes the plurality of second-type identifiers. The segment routing device sends the second packet to the second network.

Abstract: This application discloses a method that includes obtaining by a network device an original segment list corresponding to a packet forwarding path, where the original segment list includes original segment identifiers that are sequentially arranged, and each of the original segment identifiers that are sequentially arranged corresponds to one node or link on the packet forwarding path. The method further includes comparing by the network device a plurality of successively adjacent original segment identifiers in the original segment list, to generate a plurality of successively adjacent compressed segment identifiers, where a length of each compressed segment identifier is less than a length of a corresponding original segment identifier, and generating by the network device a compressed segment list, where the compressed segment list includes a plurality of compressed segment identifiers, and the compressed segment list is used to forward a packet along the packet forwarding path.

Abstract: Embodiments of this application provide a paging method and an apparatus, to reduce paging overheads, and relate to the field of wireless communication technologies. In the method, a serving network device may receive positioning area information. A positioning area represented by the positioning area information herein is used by a terminal device to send an SRS in an inactive mode or an idle mode. The serving network device may send a paging message to one or more neighboring network devices in a paging area. The paging area may be determined based on the positioning area.
