This document describes Virtual Circuit Connection Verification (VCCV) procedures for use with psuedowire connections. VCCV supports connection verification applications for pseudowire VCs regardless of the underlying MPLS or IP tunnel technology. VCCV makes use of IP based protocols such as Ping and MPLS-Ping to perform operations and maintenance functions. A network operator may use the VCCV procedures to test the network's forwarding plane liveliness.
