Abstract
The present invention relates to a method for selecting a label switched path LSP, which is applied in an MPLS network and includes: determining an energy engineering parameter of a network element itself in the network, where the network element is a network element on any candidate LSP between a source network element and a destination network element; receiving, by the network element, Interior Gateway Protocol IGP messages sent by other network elements in the network, and obtaining an energy engineering parameter of each of the other network elements; and selecting, according to the energy engineering parameter of the network element itself and the energy engineering parameter of each of the other network elements, a transmission path for the source network element and the destination network element.
