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.
