All rights granted to MEF under applicable copyright laws are expressly reserved. No permission is granted to any recipient or user of MEF publications to modify any of the information contained therein and MEF disclaims all responsibility and liability for such modifications.

Technical Committee Specifications are grouped below by Carrier Ethernet Service Definitions, Architecture, Management, Service Operations, and Test Suites. Most specifications are introduced by a Powerpoint overview presentation that gives background and explanations that are in addition to the normative definitions in the specifications. The superseded specifications are included at the foot of the table.

Service Definitions

MEF Carrier Ethernet Service Definitions   Overview
PPT
Download
Spec
 

6.2

Uses the service attributes and parameters that are defined in the MEF “Ethernet Services Attributes Phase 2” and applies them to create different Ethernet services. This document defines three generic service constructs called Ethernet Service types and specifies their associated service attributes and parameters used to create Point-to-Point, Multipoint-to-Multipoint, and Rooted-Multipoint Ethernet services. It defines the Ethernet Services (EPL, EVPL, E-Line, E-LAN, E-Tree, etc.) with Service Attributes and parameters as specified in MEF 10.3, “Ethernet Services Attributes” and in MEF 45, “Multi-CEN Layer 2 Control Protocol”

 

8

Gives precise instructions for implementing interoperable CES equipment that reliably transport TDM circuits across Carrier Ethernet Networks while meeting the required performance of circuit emulated TDM services as defined in ITU-T and ANSI TDM standards

 

22.2

Identifies the requirements for MEF Ethernet Services and MEF External Interfaces for use in Mobile Backhaul networks based on MEF specifications

   

33

Defines Ethernet Access Services, ENNI to UNI Carrier Ethernet services in contrast to the EVC-based (UNI to UNI) services which are defined in MEF 6.1

 

43

Specifies the functionality offered by an Access Provider (AP) that, when combined with an Ethernet-Access (E-Access) Service, allows a Service Provider (SP) to monitor and configure selected objects associated with a given UNI and one or more OVC End Points at that UNI in the AP’s network.

   

47

This document identifies the requirements for MEF Ethernet Services and MEF External Interfaces (EIs such as UNIs) as well as a management interface for use in support of Cloud Services.

   

51

This document specifies Operator Virtual Connection (OVC) Services based mainly on the service attributes defined in MEF 26.1; there are also some service attributes defined in this document that go beyond MEF 26.1.

   

Service Attributes

MEF Carrier Ethernet Service Attributes   Overview
PPT
Download
Spec

10.3

The attributes of Ethernet Services observable at a User Network Interface (UNI) and from UNI-to-UNI are defined. In addition, a frame-work for defining specific instances of Ethernet Services is described. These are used in MEF 6.1

   

 

10.3.1

This amendment makes the following changes to MEF 10.3: section 8.8.7 is added to define the Composite Performance Metric, new terms are added to Table 1 of MEF 10.3., a new entry is added to Reference of MEF 10.3., and a new appendix is added to MEF 10.3 as Appendix D.

   

 

10.3.2

This document amends MEF 10.3 to enhance the UNI Resiliency Service Attribute to include multiple physical links that can carry different Service Frames simultaneously at a UNI.

 

23.2

This Implementation Agreement formalizes the CoS Name and defines three specific CoS Names called Class of Service Labels (CoS Labels). This IA also provides guidelines for CoS Names, in general, in terms of how the performance objectives for OVCs are composed into performance objectives for EVCs.

 

26.2

This document contains specifications for interconnecting Operator CENs in order to support MEF Forum Ethernet Services. This Technical Specification specifies:

  • The requirements at the ENNI reference point as well as the interface functionality in sufficient detail to ensure interoperability between two Operator CENs.
  • The connectivity attributes UNI to UNI, UNI to ENNI, and ENNI to ENNI such that multiple Operator CENs can be interconnected and the Ethernet services and Service Attributes in MEF 6.2, MEF 10.3, and MEF 51 can be realized.
  • The concept of the Super Operator which allows an Operator, acting as a Super Operator, to combine multiple Operator CENs together and make them appear as a single Operator CEN to a Service Provider or another Super Operator.
   

41

This document specifies a Generic Token Bucket Algorithm based on the Bandwidth Profile Algorithm specified in MEF 10.3 It is expected that other documents can reference this specification for describing new Bandwidth Profiles and methods for regulating the use of
other resources.

   

45

This document specifies the service attributes and requirements for handling Layer 2 Control Protocol (L2CP) Frames in a Carrier Ethernet Network.

   

Architecture 

MEF Architecture   Overview
PPT

Spec

2

Defines a broad frame work for hop-by-hop and end-to-end service level protection.

 

3

Circuit Emulation Service “tunnels” TDM traffic through a Carrier Ethernet network allowing inclusion of legacy networks within a Carrier Ethernet environment

 

4

Introduces the framework and terminology for the services (Eth) layer

 

11

Defines a split demarcation function between the customer (Subscriber), and the Service Provider

 

12.2

Defines the architecture framework to model the Ethernet Services Layer of MEF compliant Carrier Ethernet Networks.

 

13

This allows existing Ethernet devices (switch, router, workstation, etc) acting as Customer Edge devices to be compliant to this IA with no additional software or hardware upgrades

 

20

Specifies MEF UNI characteristics and operation in which customer side of the UNI is automatically configured by the network side of the UNI allowing verification of SLA and UNI connectivity. Additional objectives include support for Ethernet OAM (802.3ah, 802.1ag) over the UNI. Required for support of ELMI

   

29

Defines an abstract set of Ethernet Service Constructs that are widely applicable regardless of how the UNI-to-UNI Network may be sugmented by providers

   

32

Contains requirements for protecting Ethernet Services at an External Interface against link or a Network Element (NE) failure. This specification identifies resiliency requirements at external interfaces applicable to MEF Service and associated Service End Points.

This document standardizes the following: The test PDUs that are exchanged between devices during the test, the control protocol used to configure SAT test, and the control PDUs that are exchanged between the devices in two operators’ networks.

The control protocol provides the ability to configure and control the SAT steps and to fetch test results at the completion of the test. The requirements defined within this document are based on the SAT process as defined in section 10 of the Carrier Ethernet Service Activation Testing Technical Specification (MEF 48).

The MEF Technical Committee develops technical specifications and implementation agreements to effect standardization, interoperability and accelerate deployment of Carrier Ethernet worldwide.

Four Work Areas

The Technical Committee focuses on four broad areas of development work: Services, Architecture, Management, Test & Measurement. Each area has teams working on specific projects to define and advance Carrier Ethernet in support of its worldwide adoption. The Technical Specifications page shows full details of all current and retired specifications.

Public Resources

 
Technical Committee Areas of Work

 

Services

Mandated to define Carrier Ethernet services models, definitions and service parameters and attributes. The focus is to define common services terminology along with the associate attributes and parameters to allow equipment manufacturers, service providers and enterprise customers to speak in a common language for standardized Carrier Ethernet implementations.

 

Architecture

Mandated to develop an architectural reference model and set of common linguistic tools for the technical committee work. The layered MEN/CEN architecture is defined including the multiple base transport layers, the single Ethernet Services layer and the application layers that ride on top of the Ethernet Services. Each layer has been further decomposed into the Adaptation, Connection and Termination elements. This critical area is completed with the UNI framework allowing users to seamlessly access the Carrier Ethernet network from the customer premise equipment to the core backbone.

Management

Mandated to develop Carrier Ethernet service operations, administration and maintenance (OA&M) requirements, models and definitions. This area is focused on defining and ensuring that network management is effective and interoperable across Carrier Ethernet platforms. This includes normal network implementations that include multi-vendor solutions and integration into legacy network architectures.

Test and Measurement

Mandated to define suites of test methodologies and test cases that matching the clauses in the related MEF Specifications. Their intended use is as the basis for the MEF Certification Programs test plans to ensure the functional conformance of both products and services to MEF Specifications.

 

Types of Specifications

Technical Specifications

These include architectural and abstract models required to create a robust platform of technical requirements and definitions. They are the principal documents that define mandatory and optional elements, attributes etc., of the elements of a Carrier Ethernet network (UNI, Services, NNI, etc).

Implementation Agreements

Implementation Agreements(IAs) typically quantify specific parameters and attributes called out in the technical specifications so that consistent, interoperable implementation can occur.

Abstract Test Suites

Abstract Test Suites are the comprehensive sets of test cases to be used to evaluate conformance to certain MEF specifications as described under Test and Measurement above.

This page summarizes current technical projects in development by the MEF Technical Committee.

Driven by Member Contributions

At the heart of the market acceptance of Carrier Ethernet is work of the Technical Committee. This work is driven solely by the contributions of members advancing the work by creating new common standards for implementation of service together with the supporting architectural, management and testing specifications. This has always presented an opportunity for those willing to contribute to advances for the benefit of the industry and their own member companies.

Thousands of Technical Contributions

More than 50 Technical Committee documents have been published based on the many thousands of technical contributions and the dedication of the MEF membership. Contributing members are recognized on the Chairs, Editors and awards pages on the site. Please pull down the "About MEF" menu on the top right of this page.

A detailed Technical Dashboard is available on the MEF Members site Wiki. Currently, around 20 active projects cover updates to existing services, extensions for dynamic cloud service delivery and management, expansion of Mobile Backhaul for additional Small Cell functionality, new interconnect and CE transit services and other services management projects.
