Applicability of MPLS Transport Profile for Ring Topologies
RFC 6974, “Applicability of MPLS Transport Profile for Ring Topologies”, is an Informational document published in July 2013 by Y. Weingarten, S. Bryant, D. Ceccarelli, D. Caviglia, F. Fondelli, M. Corsi, B. Wu, X. Dai. The canonical text is published by the RFC Editor.
Abstract
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.
