Abstract:
   This document specifies a fast mechanism for protecting pseudowires
   against egress endpoint failures, including egress attachment circuit
   failure, egress PE failure, multi-segment PW terminating PE failure,
   and multi-segment PW switching PE failure.  Operating on the basis of
   multi-homed CE, redundant PWs, upstream label assignment and context
   specific label switching, the mechanism enables local repair to be
   performed by the router upstream adjacent to a failure.  The router
   can restore a PW in the order of tens of milliseconds, by rerouting
   traffic around the failure to a protector through a pre-established
   bypass tunnel.  Therefore, the mechanism can be used to reduce
   traffic loss before global repair reacts to the failure and the
   network converges on the topology changes due to the failure.
