Patent ID: 8165038

Claim:
A method comprising: receiving configuration data associated with devices in a network at a network analysis system that is configured to provide a model of the network, identifying, by the network analysis system, a plurality of tunnel definitions in the configuration data, identifying, by the network analysis system, a source device and a destination device of a select tunnel, determining, by the network analysis system, a pair of interfaces corresponding to source and destination interfaces of the select tunnel at the source and destination devices, based on complementary data in the tunnel definitions at the source and destination devices, determining, by the network analysis system, a physical path between the source and destination interfaces corresponding to the select tunnel, and enhancing, by the network analysis system, the model of the network based on the determination of the physical path between the source and destination interfaces corresponding to the select tunnel, wherein determining the physical path includes a hierarchical search that includes a search based on logical connections, and a search based on physical connections.
