<p>A method for mapping a network topology request to a physical network is described. For each of a plurality of primary nodes (A, B) included in the network topology request a plurality of nodes in the physical network is determined that meet a primary resource requirement associated with the primary node, and from the nodes determined one or more node pairs connected in the physical network by a path are selected that meets a backup connection requirement for a connection between a primary node (A, B) and its backup node (A', B'). Then, the paths (134') in the physical network between node pairs (A-A', B-B') associated with interconnected primary nodes (A, B) are determined.</p> |
