1. Underlay Connectivity:

Underlay Connectivity Services

E.g. MEF 3.0 Optical Transport, Carrier Ethernet, IP

MEF 3.0 Underlay Connectivity Service standards, such as Carrier Ethernet, provide technology-agnostic service capabilities for service providers to connect subscribers, e.g. an enterprise and its office locations. Each service provider has multiple endpoints, which may span a city, or the planet. Modern global enterprises often require multiple providers to partner together to deliver the connectivity they require.

2. Automation Between Providers:

Inter-provider Service Automation

Federating Network & Cloud Providers with MEF LSO Sonata APIs

To manage the digital velocity enterprises need, service providers need to interoperate seamlessly in an automated fashion. MEF Lifecycle Service Orchestration (LSO) APIs support this requirement. Specifically, LSO Sonata APIs, provide the business-layer automation for services based on MEF 3.0 Underlay Connectivity Service standards like Carrier Ethernet.

3. SD‑WAN Overlay:

The Overlay Digital Service Layer

MEF 3.0 SD-WAN

MEF’s SD-WAN service standard provides a policy-driven, application-centric approach to creating a flexible, software-defined overlay, which sits atop the various underlay connectivity services. Enterprises are clamoring for this overlay experience delivered as a managed service.

4. Digital Services Platform for Growth:

Fully Orchestrated Underlay & Overlay Services

Growth Platform for New Digital Services

By using MEF LSO standards to automate both within and between providers at the underlay connectivity layer, that is synchronized with the SD-WAN overlay layer, service providers are empowered to deliver modern digital services to their enterprise customers e.g. Mixed Reality, IoT and security services.
