Technical Summary

   Two useful Operations, Administration, and Maintenance (OAM)
   functions in a transport network are "lock" and "loopback". The lock
   function enables an operator to lock a transport path such that it
   does not carry client traffic, but can continue to carry OAM messages
   and may carry test traffic. The loopback function allows an operator
   to set a specific node on the transport path into loopback mode such
   that it returns all received data.

   This document specifies the lock function for MPLS networks and
   describes how the loopback function operates in MPLS networks.
