Document Type and Number:
WIPO Patent Application WO/2021/008497
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and provided are a data transmission method, a network node, and a storage medium. In the present application, a bottom layer segment identifier corresponding to a bottom layer path is designed, and the bottom layer segment identifier is issued such that nodes in a segment routing network may perceive the bottom layer path by means of the bottom layer segment identifier; thus, when transmitting a data packet, according to a bottom layer segment identifier carried in the data packet, the data packet can be transmitted by means of the bottom layer path corresponding to the bottom layer segment identifier. Therefore, according to service requirements, it can be indicated which bottom layer path is used to transmit a data packet such that different data packets can be transmitted by means of different bottom layer paths, thus improving flexibility and facilitating traffic planning.
