Recommendation ITU-T G.8152.2/Y.1375.2 specifies resilience management information and data models for a multi-protocol label switching-transport profile (MPLS-TP) network element (NE) as specified in Recommendations ITU-T G.8131 and ITU-T G.8132. The information model is interface protocol neutral and specified using the unified modelling language (UML). The information model in Recommendation G.8152.2/Y.1375.2 is derived through pruning and refactoring from the Recommendation ITU-T G.7711/Y.1702 core information model and Recommendation ITU‑T G.8152/Y.1375 foundation MPLS-TP NE information model. The data models are interface protocol specific and translated from the information model with the assistance of automated translation tooling. The specific data models considered in Recommendation ITU-T G.8152.2/Y.1375.2 include, but are not limited to, those of the yet another next generation (YANG) type. Amendment 1 updates the UML model and data model for MPLS-TP linear protection, adds the relationship between MPLS-TP linear protection model and the IETF reverse-engineered UML modes and adds Appendix II for the examples. Amendment 2 adds Appendix IV to illustrate the relationship between the MPLS-TP linear protection state and the current traffic being transported and updates the MPLS-TP shared ring protection (MSRP) UML model and yang model. Edition 2.0 updates the protection state for the linear protection and shared ring protection, including Table 7-2, Table 7-6, Figure 7-4, Figure 7-7, UML model and Yang model. Add the legal text in the YANG files.
