Hi SPRING,

We have just updated the document of draft-chen-rtgwg-srv6-midpoint-protection for SRv6 midpoint protection. Considering that there are relevant work and discussions in SPRING as well, it is appreciated if you could review our draft and give comments. We will also try to request a time slot in IETF 111 to collect feedback.

Thanks!
Xuesong

Abstract:
   The current local repair mechanism, e.g., TI-LFA, allows local repair
   actions on the direct neighbors of the failed node to temporarily
   route traffic to the destination.  This mechanism could not work
   properly when the failure happens in the destination point or the
   link connected to the destination.  In SRv6 TE, the IPv6 destination
   address in the outer IPv6 header could be the dedicated endpoint of
   the TE path rather than the destination of the TE path.  When the
   endpoint fails, local repair couldn't work on the direct neighbor of
   the failed endpoint either.  This document defines midpoint
   protection, which enables the direct neighbor of the failed endpoint
   to do the function of the endpoint, replace the IPv6 destination
   address to the other endpoint, and choose the next hop based on the
   new destination address.
