MEF 3.0 certification enables communications service and technology providers to certify compliance with latest releases of MEF 3.0 service and LSO API specifications. MEF 3.0 orchestration-ready services provide the highest level of performance, assurance, and agility available in the market.

Revolutionary, Agile Certification Model

MEF has increased the agility of its popular service and equipment certification programs to accelerate availability and adoption of MEF 3.0 services and technologies.

MEF 3.0 certification is delivered by MEF’s testing partner, Iometrix, on a revolutionary on-demand, cloud-based virtual test platform with user-initiated testing.

The MEF 3.0 framework provides the ability, for the first time, to move to an incremental release approach for both services and LSO APIs and to tightly align certification with each release.

MEF 3.0 CE Certification Now Available

MEF 3.0 certification currently is available for orchestration-ready MEF 3.0 CE services, but will be extended in the future to include Layer 1, IP, SD-WAN, and virtualized services, along with the various LSO APIs used for inter-provider and intra-provider service orchestration.

The MEF 3.0 CE Certification Blueprint specifies the service attributes and parameters to be verified during MEF 3.0 CE certification testing. This blueprint will be updated as new LSO API and service specifications become available.

MEF 3.0 CE enhances CE 2.0 E-line, E-LAN, and E-Tree services with new and re-defined service attributes included in MEF specifications published between 2013 and 2017. MEF 3.0 CE also includes new Access E-line and Transit E-line services based on specifications published in 2016 and 2017.

See the figure below for a full list of MEF 3.0 CE specifications.
