Hi,

We have submitted a new revision of the "PW Endpoint Fast Failure Protection" draft. The main change in this revision is the definition of an "Egress Protection Capability TLV" that a protector advertises to announce its capability. 

Please review this change and the latest draft, and provide your comments. We have request a time slot to present it in Berlin.

Thanks,

-Yimin Shen

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.
