Abstract:
   This document specifies a fast mechanism for protecting pseudowires
   (PWs) transported by IP/MPLS tunnels against egress endpoint
   failures, including egress AC (attachment circuit) failure, egress PE
   (provider edge) failure, multi-segment PW terminating PE failure, and
   multi-segment PW switching PE failure.  Operating on the basis of
   multi-homed CE (customer edge), 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.
