ENHANCED PATH SELECTION SCHEME FOR EQUAL COST PATHS IN COMMUNICATION NETWORKS

摘要

In one embodiment, a node in a communication network receives a label switched path (LSP) request and in response, the node determines at least two equal cost paths, each path having one or more path-nodes. The node may then further determine a total bandwidth-based transition value for each path of the at least two equal cost paths and selects the path having a lower total transition value. Once selected, the node may establish the requested LSP over the selected path.

1. A method, comprising:
receiving, at a node in a communication network, a label switched path (LSP) request; determining, in response to the LSP request, at least two equal cost paths, each path of the at least two equal cost paths having one or more path-nodes; determining a total bandwidth-based transition value for each path of the at least two equal cost paths; selecting the path having a lower total transition value; and establishing the requested LSP over the selected path.
