Summary

Recommendation ITU-T G.874.1 provides a protocol-neutral management information model for managing network elements in the optical transport network (OTN). The model contains the managed entities and their properties that are useful to describe the information exchanged across interfaces defined in the ITU-T M.3010 telecommunications management network (TMN) architecture. The protocol-neutral management information model shall be used as the base for defining protocol‑specific management information models, for example, CMISE, CORBA and SNMP information models. Mapping from the protocol-neutral entities into protocol-specific objects is a decision of the specific protocol modelling design and should be described in the protocol-specific information model Recommendations.

The 2012 revision of this Recommendation has updated the management information model to support the management of the new transport functions that have been introduced in the 2010 revision of Recommendation ITU-T G.798 and also to support the management requirements enhancement introduced in the 2010 revision of Recommendation ITU-T G.874.

Amendment 1 (08/2013), which has been integrated into this text, enhances the model to cover delay measurement, automatic protection switching configuration, tributary slot configuration, and ODU type and rate configuration, and to remove the counting of IAE and BIAE initially present in the base text.

This Recommendation includes an electronic attachment containing the UML model file of the ITU‑T G.874.1 OTN NE management-protocol-neutral information model.
