Abstract: In one embodiment, a method includes receiving at a node in a first network, information identifying a spare interface between a first network device in the first network and a second network device in a second network, and using the spare interface to create a path in the first network if the spare interface is compatible. The spare interface information includes connectivity and compatibility information.

Abstract: Bandwidth usage for an existing communication tunnel between a first device and second device is monitored. A determination is made that additional bandwidth is required for communication between the first network device and the second network device. A determination is made that for the addition of the additional bandwidth would exceed available bandwidth for the existing tunnel. Additional bandwidth is established between the first network device and the second network device.

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.
