Abstract:
1. A method for mitigating traffic loss in a multiprotocol label switching (MPLS) network, comprising: measuring, at a network element, energy utilization of at least one of a line card and a switch fabric card that are configured to carry a traffic engineering (TE) capable link; converting the energy utilization measurement to a normalized energy consumption indicator for the at least one of the line card and the switch fabric card; optimizing, based on the normalized energy consumption indicator, a route of a label switched path in the MPLS network so the route avoids the at least one of the line card and the switch fabric card; advertising the normalized energy consumption indicator to a second network element with a type length value element responsive to the normalized energy consumption indicator crossing a configured threshold, wherein the configured threshold is utilized to minimize advertisements; and utilizing the normalized energy consumption at the second network element to detect degradation for a protection switchover of the label switched path.
