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.

Methods and systems for determining a network data path

Enhanced operation is attained for packet networks with a performance management operations system (PMOS) that receives information from network elements concerning loads carries and lost packets, receives threshold and other parameter information for a network management console, performs various calculations on the received information, and develops recommendations for setting of adjustable network elements controls that affect the quality of service that those elements provide. For those network elements that are capable of receiving operation control signals from the PMOS and that the network management console ceded a measure of control to the PMOS, the developed recommendations are converted to control signals that are directly applied by the PMOS to the network elements to control the network elements' operations.
