Abstract:
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.
