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: Provided is a method and device for implementing Virtual Private Network (VPN) cross-domain, and a border node. The method includes that: a border node receives a advertisement message which carries VPN route information and is sent by a first node to a second node, wherein the border node supports Internet Protocol Version 6 Segment Routing (SRv6) capability, and the first node and the second node belong to different domains; and the border node assigns VPN identity information to a VPN route corresponding to the VPN route information, adds the VPN identity information into the advertisement message and sends the advertisement message to the second node, wherein the VPN identity information includes at least one of: a VPN Segment ID (SID) and a VPN label.
