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. 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 the 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.
