Abstract
Disclosed is an apparatus comprising a plurality of path computation elements (PCEs) associated with a plurality of inter-coupled domains and configured to communicate with a path computation client (PCC) associated with one of the domains and to implement a Forward Search Path Computation (FSPC) for a preferred path crossing the domains from a source node in a source domain of the plurality of inter-coupled domains to a destination node in a destination domain of the plurality of inter-coupled domains, wherein the preferred path is computed without using a determined order of the domains from the source domain to the destination domain.
