ABSTRACT:
Methods and systems for path determining a network data path are described. In one embodiment, equal cost multiple paths (ECMPs) for a proposed TE tunnel on a network may be determined. The proposed TE tunnel may extend between a head-end tunneling capable router and a tail-end tunneling capable router. The network may further comprise inter router links extending between tunneling capable routers. For each inter router link of at least a portion of the inter router links, a usage count may be established for that inter router link. The usage count may be the number of ECMPs for the proposed TE tunnel that use that inter router link. A tunnel path may be selected from the ECMPs for the proposed TE tunnel that has the lowest usage count of the inter router links. The selected tunnel path may be added to a model of the network. Additional methods and systems are disclosed.
