This document describes a method for generating an aggregated pseudowire status message on Multi-Protocol Label Switching (MPLS) network Label Switched Path (LSP). The method for transmitting the pseudowire (PW) status information is not new, however this protocol extension allows a Service Provider (SP) to reliably monitor the individual PW status while not overwhelming the network of multiple periodic status messages. This is achieved by sending a single cumulative status message for all the PWs grouped in the same LSP.
