Abstract:

A method of determining a path through a network. Structures in a network are grouped into structure groups, each structure group comprising at least two nodes. Virtual circuit information for every pair of nodes in the structure groups is determined, and connections between the structure groups is determined. A least cost path is determined from a first node to a second node using the virtual circuit information and connection information.
