This document presents an applicability of existing MPLS protection mechanisms, both local and end-to-end, to the MPLS Transport Profile (MPLS-TP) in ring topologies. This document does not propose any new mechanisms or protocols. Requirements for MPLS-TP protection especially for protection in ring topologies are discussed in "Requirements of an MPLS Transport Profile" (RFC 5654) and "MPLS Transport Profile (MPLS-TP) Survivability Framework" (RFC 6372). This document discusses how most of the requirements are met by applying linear protection as defined in RFC 6378 in a ring topology.

For the definition of Status, see RFC 2026.

For the definition of Stream, see RFC 4844.
