Organization: ITU-T
Publication Date: 1 July 2014
Status: active
Page Count: 34
scope:

This Recommendation provides architecture and mechanisms for linear protection switching for MPLS transport profile (MPLS-TP) networks.

The automatic protection coordination protocol, and 1+1 and 1:1 protection architecture are defined in this Recommendation. Other protection architecture types are for further study.

This Recommendation describes the protection switching functionality for point-to-point connections using the automatic protection switching (APS) mode defined in [IETF RFC 7271].

This Recommendation provides a representation of the MPLS-TP technology using the methodologies that have been used for other transport technologies (e.g., synchronous digital hierarchy (SDH), optical transport network (OTN) and Ethernet).1

1 This ITU-T Recommendation is intended to be aligned with the IETF MPLS RFCs normatively referenced by this Recommendation.
