Title : PW Endpoint Fast Failure Protection
Author(s) : Yimin Shen

Wim Henderickx
Filename : draft-shen-pwe3-endpoint-fast-protection-01.txt
Pages : 27
Date : 2012-02-27
This document specifies a fast protection mechanism for pseudowires
(PWs) against egress attachment circuit (AC) failure, egress PE
failure, and 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 immediately upon a failure. In particular, the router at
point of local repair (PLR) can redirect PW traffic to a protector
via a bypass LSP in the order of tens of milliseconds, achieving fast
protection that is comparable to RSVP fast-reroute.
