ITU-T Y.1375.2 PDF

This Recommendation specifies resilience information models and data models for a multi-protocol label switching-transport profile (MPLS-TP) transport network element (NE) to support specific interface protocols and specific management and control functions. The information models are interface protocol neutral and derived through pruning and refactoring from the ITU-T G.7711 core information model and ITU-T G.8152 foundation MPLS-TP NE information model. The data models are interface protocol specific and translated from these information models. The specific data models considered in this Recommendation include, but are not limited to, those of the yet another next generation (YANG) type. The specific management and control functions for resilience covered by this Recommendation include ITU-T G.8131 MPLS-TP linear protection switching and ITU-T G.8132 MPLS-TP shared ring protection (MSRP) switching.

The YANG modules of this Recommendation aim to be compatible with and when necessary extend the relevant generic ones developed by the Internet Engineering Task Force (IETF) for the ITU-T G.8131 and ITU-T G.8132 resilience functions.
