An Industry Initiative for Third Generation Network and Services
This paper describes an industry vision for the evolution and transformation of network connectivity services and the networks used to deliver them. The MEF refers to this vision as the “Third Network” where the Third Network combines the on-demand agility and ubiquity of the Internet with the performance and security assurances of today’s business grade networks (i.e.: Carrier Ethernet 2.0 and MPLS).Download the PDF →

Lifecycle Service Orchestration (LSO): Reference Architecture and Framework
LSO is an agile approach to streamlining and automating the service lifecycle in a sustainable fashion for coordinated management and control across all network domains responsible for delivering an end-to-end Connectivity Service (e.g., Carrier Ethernet, IP VPN, MPLS, etc.). This document describes a Reference Architecture and Framework for orchestrating the service lifecycle.
Interface Profile Specification – Service Configuration and Activation
This Interface Profile Specification specifies Legato Management Interface in support of MEF 6.2 Services and is a realization of relevant classes from MEF 7.3 Information Model. The LEGATO_SCA Interface is for use at a Service Orchestrator Function for interfacing with Business Applications as described in MEF LSO RA and process for Service Configuration & Activation.
Ethernet Ordering Technical Specification - Business Requirements and Use Cases
This document represents the cumulative work between MEF and ATIS Ordering and Billing Forum (OBF) to identify the common ordering attributes and processes needed to support inter-carrier Product Ordering of Ethernet Services worldwide. This document supports the requirements defined in the MEF Lifecycle Service Orchestration (LSO) Reference Architecture and Framework (MEF 55, LSO RA) requirements for Ordering over the Sonata interface (Service Provider <-> Partner interactions).
The MEF spearheaded the creation of a $50+ billion market for Carrier Ethernet Services. Ethernet now dominates the WAN and has been one of the fastest growing segments of the data service portfolios over the past decade.
Carrier Ethernet 2.0 (CE 2.0) is a ubiquitous, standardized, carrier-class Service and Network defined by five attributes that distinguish it from familiar LAN-based Ethernet. Carrier Ethernet 2.0 networks and services enable multiple classes of service (Multi-CoS) and manageability over interconnected provider networks.
In recent years, MEF has focused on accelerating worldwide deployment and interconnection of CE 2.0 networks to create a firm foundation for Third Network services. As of today, there are now 77+ service providers who offer CE 2.0 certified services, and much more are in the pipeline.
The Class of Service extensions of CE 2.0 standardizes performance objectives across a variety of geographic “Performance Tiers” and applications. This results in improved QoS and optimizes efficiency, especially when utilizing the MEF’s VLAN-based services. It is not the support of multiple classes of service itself which is new. Rather, it is the performance objectives for each service class defined in the specification. This provides the knowledge of what performance you can expect for each class supported.
Interconnected refers to the standardized exchange of Carrier Ethernet traffic between providers and for eventual delivery in the Access network utilizing the E-Access/E-Transit Services types while preserving the attributes of the service. This allows providers to engineer multiple interconnected networks as a single network from the user’s perspective, with a single SLA.
New management functions standardize fault management and performance monitoring at levels not previously possible for services delivered across multiple providers. This enables sectionalization of faults down to individual virtual connections.
This explains why we term the characteristics of CE 2.0 as “Multi-CoS, Managed, Interconnected”
Future of Carrier Ethernet
For orchestrated services to evolve and work over multiple operator networks, it is important for CE 2.0 providers to not behave as independent islands but instead to be integrated into a seamless, scalable connectivity fabric cutting across geographic regions. MEF has advanced important initiatives like the Ethernet Interconnection Points Project (MEF 54) to ensure alignment of service parameters and therefore streamline deployment of fully-featured interconnections between service providers.
MEF also has taken a market-leading role in showing how CE 2.0 services can be implemented with NFV and SDN by publishing several white papers on these topics.
A key benefit of Carrier Ethernet is its ability to provide consistent, cost-efficient, high-performance services delivered to use connected over the widest variety of access networks in any location. The source of this featured is the layered services architecture, shown on the right.
Data moves from UNI to UNI across "the network" with a layered architecture. When traffic moves between ETH domains it does so at the TRAN layer. This allows Carrier Ethernet service frames to be agnostic to the networks that it traverses.

MEF service types below are defined to be simple port-based “private” services or VLAN-aware “virtual-private” services where the former is a single service is delivered at a single port called a User-to-Network Interface (UNI) and the latter enables multiple services to be delivered at a UNI.
Provides the simplest form of connectivity and is the most popular service for providing Internet access and site-to-site connectivity.
Services consist of Ethernet Private Line (EPL) and Ethernet Virtual Private Line (EVPL) for port-based and VLAN-aware services, respectively
Allows the Wide Area Network locations to appear as if they are connected to the in-house or campus Local Area Network.
