Abstract: Provided are a method and apparatus for determining identification information about a cross-domain path, and a storage medium. The method includes: receiving a path computation request from a first child path computation element (PCE), wherein the path computation request carries a compression identifier for identifying compression of path segments and a path set-up type (PST); after identification information about a path from a source node to a destination node is acquired, instructing, according to the compression identifier and the PST, each of sub-PCEs corresponding to the one or more path segments to compress identification information about a respective one of the one or more path segments; and receiving the compressed identification information about each path segment.

Abstract: The present disclosure provides a packet encapsulation method, including: determining a segment routing-traffic engineering (SR-TE) path; generating, according to a segment identifier (SID) of each node in the SR-TE path, an SID list, where each node supports a plurality of unified-SID encapsulation types (UETs) corresponding to SIDs of different lengths, and in the SID list, the SID of at least a node serving as an intermediate node of the SR-TE path is the SID having the non-longest length in the plurality of SIDs corresponding to the node; forming a segment routing header (SRH) from the SID list; and encapsulating an initial packet with the SRH to obtain a final packet. The present disclosure further provides a packet forwarding method, a UET announcement method, an electronic device, and a computer-readable storage medium. The final packet obtained by the packet encapsulation method has a higher load rate.
