Hi Kireeti,

I see the definition section of this draft briefly describes the architecture of ring LSP, and section 3.3, 3.4  specify the installation of primary and protection labels.  Since section 2.1 of draft-cheng-mpls-tp-shared-ring-protection specified the architecture of ring tunnels and the label distribution on rings, maybe we can build the ring LSP architecture based on that work.

Section 3.6 Protection describes the general protection mechanism used for ring LSPs, while the details of several protection mechanisms, like wrapping, short-wrapping and steering in ring topology were specified in section 2.2~2.4 of draft-cheng-mpls-tp-shared-ring-protection. IMO it would be helpful if the applicability of these protection mechanisms can be discussed or reused.

Regarding configuration and signaling, both are interesting topics for MPLS in ring topology, and I’d appreciate hearing your thoughts on them.

Best regards,
Jie

Hi Folks,

This is a draft on making MPLS more efficient in ring networks.  I have come around to understanding that:
a) rings are a special topology (there was a time that I didn't appreciate that);
b) MPLS is pretty inefficient in rings (that is/was quite obvious).

This draft attempts to fix that, both by making protection much more efficient, and by making configuration much easier.

Your comments are highly welcome!

Cheers,
Kireeti.

Name:           draft-kompella-mpls-rmr
Revision:       00
Title:          Resilient MPLS Rings
Document date:  2014-10-26
Group:          Individual Submission
Pages:          7
URL:            http://www.ietf.org/internet-drafts/draft-kompella-mpls-rmr-00.txt

Htmlized:       http://tools.ietf.org/html/draft-kompella-mpls-rmr-00


Abstract:
   This document describes the use of the MPLS control and data planes
   on ring topologies.  It describes the special nature of rings, and
   proceeds to show how MPLS can be effectively used in such topologies.
   It describes how MPLS rings are configured, auto-discovered and
   signaled, as well as how the data plane works.  Companion documents
   describe the details of discovery and signaling for specific
   protocols.





Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org<http://tools.ietf.org>.
