Patent ID: 10397093

Abstract:
A method for acquiring a cross-domain separation path includes: when receiving a cross-domain separation path computation request, acquiring K pairs of candidate separation domain sequences according to a cross-domain network abstraction topology; traversing the K pairs of sequences, generating corresponding intra-domain path computation requests for various domains through which candidate separation domain sequences in the network pass to transmit; when receiving at least one pair of intra-domain paths for the request, configuring each of the at least one pair of intra-domain paths to a corresponding position in the K pairs of sequences, to form K pairs of candidate cross-domain separation paths; and determining one pair of cross-domain separation paths from the K pairs of paths as a computation result of the cross-domain separation path computation request to transmit. There are also disclosed another method for acquiring a cross-domain separation path, a path computation element, and a computer storage medium.
