2. Contents and Audience Contents MEF: Mission, Goals Carrier Ethernet Definition, Services, Scope and Reach The Technical Work of the MEF An Introduction to the MEF Specifications Future work and MEF Specifications in Preparation Complementary Standards Activities The Marketing Work of the MEF MEF Certification Program MEF Global Services Directory MEF Membership and Benefits Purpose This presentation gives basic information about the work of the MEF It also introduces the definitions, scope and impact of Carrier Ethernet. The intended audience includes those considering joining the MEF For the following audiences, the new work therefore gives sufficient top level information about the technical work of the MEF: To act as an overview of the work for product marketing members (especially new members of the MEF or those who haven�t had time to read the specs etc) To act as an introduction to the technical work of the MEF for Engineers of companies who are considering membership or members with new MEF related roles, To give an introduction to work in progress from the technical dashboard to help encourage new/prospective members to both join and participate/influence work in progress. To give a top down approach to non-MEF members (especially those in other standards bodies) that leads them to the individual specification overviews (that should clarify some of the trickier elements as above) and the specs themselves and get them more easily understand how to correctly implement.

3. Issues and Opportunities The MEF�s Mission: Accelerate the worldwide adoption of carrier-class Ethernet networks and services This mission is in direct response to the opportunities made available by The need and demand for a simple ubiquitous service Requirement to scale network services to enable rapid deployment of applications critical to enterprises and service providers. Availability of low cost, high bandwidth Ethernet, beyond the LAN Convergence of business, residential and wireless services

4. Global Expansion from Metro to Carrier Ethernet The Beginning: Metro Ethernet The MEF was formed in 2001 to develop ubiquitous business services for Enterprise users principally accessed over optical metropolitan networks to connect their Enterprise LANs Expansion to Carrier Ethernet The success of Metro Ethernet Services caught the imagination of the world as the concept expanded to include Worldwide services traversing national and global networks Access networks to provide availability to a much wider class of user over fiber, copper, cable, PON, and wireless Economy of scale from the resulting converged business, residential and wireless networks sharing the same infrastructure and services Scalability & rapid deployment of business applications Adoption of the certification program While retaining the cost model and simplicity of Ethernet

Key Initiative for the MEF for 2009-2011 MEF Global Interconnect Defined The interconnection of autonomous Carrier Ethernet networks to enable standardized and streamlined delivery of MEF-certified Carrier Ethernet services with end-to-end Class of Service, management and protection Strategic Opportunity for Broadband Service Providers Expand coverage Extend reach Broaden service offering Reduce costs �Globalize our network� MEF Global Interconnect ProgramStandardizing and Simplifying Interconnections The Global Interconnect program is a key initiative for the MEF for the next several years. The Global Interconnect initiative is the third phase of developing the Carrier Ethernet suite. Phase 1 being Architecture and Definition, Phase 2 being Implementation and Certification. Operators have been establishing interconnects as needed in recent years, and the MEF goal is to bring standardization to the process � ultimately benefiting the enterprise customers with a consistent global service delivery.The Global Interconnect program is a key initiative for the MEF for the next several years.
