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 be used
to reduce traffic loss before a global repair mechanism reacts to the
failure or the network converges on the topology changes due to the
failure.
