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.
