PATH ESTABLISHMENT METHOD, DATA TRANSMISSION METHOD AND APPARATUS, NETWORK NODE, AND STORAGE MEDIUM

WIPO Patent Application WO/2021/180077

A1

Disclosed are a path establishment method, a data transmission method and apparatus, a network node, and a storage medium. The path establishment method comprises: a first network node generating a first message for creating a first path, and sending the first message, wherein the first message includes a first SRv6 segment identification (SID) of each network node in the first path, and the first SRv6 SID is used to establish a connection-oriented path; and the first network node is a head network node in the first path. The data transmission method comprises: on the basis of a second SRv6 SID of a first network node and data of a first service, generating and sending a data packet, wherein a destination address in the data packet is a second SRv6 SID of a next hop node of the first network node in the first path; the second SRv6 SID represents that the first path is established for the first service; the first path includes M network nodes; the data packet includes N SIDs; and N is less than M. In this way, there is no need to encapsulate an excessively long packet header for a data packet, thereby improving the processing efficiency of a network node, and reducing the processing delay.
