Pseudowire status maintenance for static pseudowires

摘要

In one embodiment, a method includes generating an aggregated pseudowire status message at a first network device in a Multi-Protocol Label Switching (MPLS) network, transmitting the 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 network, and establishing at the first network device, an aggregated pseudowire status session with the second network device upon receiving a response to the aggregated pseudowire status message on the LSP. The aggregated pseudowire status message configured to verify a current status of pseudowires on the LSP. An apparatus is also disclosed.

1. A method comprising:
generating an aggregated pseudowire status message at a first network device in a Multi-Protocol Label Switching (MPLS) 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 network, said aggregated pseudowire status message configured to verify a current status of pseudowires on the LSP and comprising a list of pseudowires for which said session verifies said current status; and if a response to said aggregated pseudowire status message is received, establishing at the first network device, an aggregated pseudowire status session with the second network device; if a response to said aggregated pseudowire status message is not received, transmitting an individual pseudowire status message; wherein the network is maintained without a dynamic control plane.
