MEF 72 Network Resource Model – Subscriber Layer 1

Abstract:

NOTE: THIS STANDARD HAS BEEN SUPERSEDED.

This specification describes the MEF Network Resource Management Information Model (NRM IM), specifically for Layer 1 Connectivity related management features. 

Lifecycle Service Orchestration Reference Architecture (LSO RA, MEF 55) extends the tradi- tional MEF scope concerning Service Modeling, from a pure view “from outside the network” to cover a range of Operational, Orchestration, and Network Management behaviors, including SDN and NFV paradigms. 

In support to MEF 55, NRM IM (MEF 59) and NRP IPS (MEF 60) have been defined to manage the Network Infrastructure, through SDN Controllers, WAN Controllers, OTN Subnet- work Managers, and other legacy Network Management Systems. 

This document adds to MEF 59 the management features related to Layer 1 Connectivity, as defined by Subscriber Layer 1 Service Attributes Technical Specification (MEF 63). This model can be used as the basis for LSO RA PRESTO Interface Profiles defining APIs for the Layer 1. 

The NRM IM structure is based on current and developing best network management solutions by ITU-T, ONF, TM Forum, to allow wider and future proof interoperability across multi-vendor and multi-technology networks. Examples of reference network management solutions are ITU-T G.7711/Y.1702, ONF TR-512, ONF TR-527, TM Forum MTNM and MTOSI.
