A METHOD FOR INFORMING AND NEGOTIATING THE MONITOR ABILITY OF THE LABEL SWITCHING CAPABILITY

摘要

A method for notifying capabilities of monitoring performance of Label Switching Path (LSP) includes: a source node sends to a destination node a request message for establishing an LSP, carrying the capabilities of monitoring performance of LSP provided by the source node; after receiving the request message, the destination node returns a response message carrying capabilities of monitoring performance of LSP provided by itself to the source node. A method for negotiating capabilities of monitoring performance of LSP includes: a source node sends to a destination node a request message for establishing an LSP, carrying the capabilities of monitoring performance of the LSP provided by the source node; the destination node matches the capabilities of monitoring performance of LSP provided by the source node with capabilities of monitoring performance of LSP provided by itself; and returns a response message carrying the matched capabilities of monitoring performance of LSP to the source node.
