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.

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. http://www.ietf.org/internet-drafts/draft-cheng-mpls-tp-shared-ring-protection-00.txt Thanks a lot for your kind review. Best regards, Weiqiang Cheng
