Abstract
A method () of end-to-end path computation across a plurality of domains () in a communication network comprises receiving () a request for a path across the plurality of domains. The method comprises computing () in a network control entity () the end-to-end path across the plurality of domains as part of a hierarchical path computation. Computing the end-to-end path comprises determining if a stored path corresponding to at least a part of the end-to-end path matches one or more criteria of the end-to-end path, and if so, using the stored path for the end-to-end path computation. The method further comprises transmitting () information indicating at least part of the stored path to a domain control entity () configured to control a said one of the plurality of domains involved in the end-to-end path.
