receive a request for a path across a plurality of domains;
compute an end-to-end path across the plurality of domains as part of a hierarchical path computation, wherein computing the end-to-end path comprises determining that a stored path matches one or more criteria of the end-to-end path, wherein the stored path is the end-to-end path across the plurality of domains, and, in response to said determining, using the stored path for the end-to-end path computation;
transmit information indicating at least part of the stored path to a domain control entity configured to control one of the plurality of domains involved in the end-to-end path.
