Abstract:
1. A method comprising: generating an aggregated pseudowire status message at a first network device in a Multi-Protocol Label Switching Transport Profile (MPLS-TP) network; transmitting said aggregated pseudowire status message to a second network device on a Label Switched Path (LSP) extending between the first and second network devices in the MPLS-TP network, said aggregated pseudowire status message configured to verify a current status of pseudowires on the LSP; establishing at the first network device, an aggregated pseudowire status session with the second network device upon receiving a response to said aggregated pseudowire status message on the LSP; and transmitting an individual pseudowire status message on each of the pseudowires on the LSP, when said response is not received at the first network device within a predefined interval.
