摘要
A method, system, source end and destination end for indexing the Label Switching Path (LSP) by means of a label are disclosed. In the present invention, a message is received that carries the Operation Administration and Maintenance (OAM) label and an inner-layer label for identifying the forward LSP, and the forward LSP with failure is indexed in accordance with the inner-layer label. Therefore, according to the present invention, in case of the backward channel being shared, Multiple Point to Point (Mp2p) LSP or Penultimate Hop Popping (PHP), the end which has received the message can index the forward LSP with failure in accordance with the label carried in the message. Thus, it is possible to support the OAM functionality in the case of the backward channel being shared, Mp2p LSP or PHP, so as to extend the application field of label indexing.
