We think it is a good idea. It partly
derives from "label merge" to construct the ring tunnels.
This manner is simply to achieve for communication equipment manufacturers,
It decreases number of labels required and configuration complexity,
and easy to deploy a high level of survivability ring network.

主题: Request for
comments on 'draft-cheng-mpls-tp-shared-ring-protection'

Hello,

Recently, the topics on ring
topology-specific protection for MPLS-TP are discussed frequently. It will help
operators to deploy a simple and effective protection as that in SDH/Sonet. In
this case, we have written a draft on ring topology-specific optimized
protection mechanism in following link. It can cover multiple adjacent nodes
and links failures. The number of LSP on the Ring is O(2N) (N is Node

number) for both P2P wrapping solution
and steering solution. Hope you could kindly help to review and comment it.

Thanks a lot for your kind review.

Best regards,
