Recommendation ITU-T G.8052.2/Y.1346.2 specifies the resilience information models and data models for the Ethernet transport network element (NE) to support specific interface protocols and specific management and control (MC) functions.

The information models are interface protocol neutral and specified using the unified modelling language (UML).

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, YANG data models.

The specific MC functions for resilience covered by this Recommendation include the ITU-T G.8031 Ethernet linear protection and ITU-T G.8032 Ethernet ring protection.

The YANG data model in this version of the Recommendation covers the Ethernet linear protection mechanism defined in Recommendation ITU-T G.8031/Y.1342.
