Abstract:
A method and an apparatus for obtaining information about a forwarding path of a data packet in segment routing (SR) include, when a first path indicated by a plurality of path identifiers in initial information is a unique shortest path from a start node on the first path to an end node on the first path, the first path is indicated using a node-segment identifier (SID) of the end node on the first path instead of the path identifiers.
