Abstract
Provided are methods and apparatus for mitigating traffic loss by using advanced traffic engineering services in a multiprotocol label switching (MPLS) network and/or a generalized multiprotocol label switching (GMPLS) network. Provided is an exemplary method that includes 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, as well as 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. Further, based on the normalized energy consumption indicator, a route of a label switched path in the MPLS network is optimized so the route avoids the at least one of the line card and the switch fabric card. The provided methods and apparatus advantageously improve throughput, reliability, and availability of MPLS and GMPLS services.
