	Title		: Signaling extension for MPLS ring protection

When using Multi-Protocol Label Switching (MPLS) Label Switched Paths 
(LSP) on a ring topology, it is needed to minimize the labels for  
protection purpose and minimize the configuration effort. Though MPLS 
Fast Re-Route [MPLS-FRR] can achieve automatic LSP service protection, 
it is not optimized as many labels are used to create lots of detour 
LSPs.  

This document describes a MPLS ring mechanism and some extensions on 
signaling protocol to facilitate the establishment of Label Switched 
Paths (LSPs) using Label Distribution Protocol [LDP] or RSVP-TE 
protocol [RSVP-TE] to achieve automated link and node protection.
