Abstract:
   This document specifies a fast mechanism for protecting pseudowires
   (PWs) 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.  Designed on the
   basis of multi-homed CE, PW redundancy, upstream label assignment and
   context specific label switching, the mechanism enables local repair
   to be performed by a router upstream adjacent to a failure.  In
   particular, the router can restore PW traffic in the order of tens of
   milliseconds, by transmitting the traffic to a protector through a
   pre-established bypass tunnel.  Therefore, the mechanism can reduce
   traffic loss before global repair reacts to the failure and the
   network converges on the topology changes due to the failure.
