4 Metro Ethernet Services

5 Metro Ethernet Services in Numbers Metro Ethernet services will replace legacy services Worldwide metro Ethernet services revenue will reach $26B in 2006 Asia will be the leading region with 50-60% of all revenues, followed by Europe and then North America. Sources: IDC 2002 and Infonetics 2003

6 Metro Ethernet Transport in Value Network Strategy Partners: – CAPEX savings of 39% vs. legacy SONET/SDH network – OPEX savings of 49% vs. legacy SONET/SDH Source: 2003 MEF

7 Metro Ethernet Transport in Numbers Ethernet, surpassing SONET/SDH in 2004, is becoming the next generation optical technology Optical Ethernet becomes a viable metro transport to deliver metro services Asia dominates metro Ethernet equipment capital expenditure Sources: Infonetics, 2003

8 Metro Ethernet Forum Mission Accelerate adoption of optical Ethernet as the technology of choice in metro networks worldwide

9 Approach to Technical Standards Build on existing standards work from other industry bodies – MEF only fills the technical gaps for Metro Ethernet Services and Transport

13 MEF Priorities and Scope The primary priorities of the MEF are to define: a. Ethernet Services for metro transport networks Such services shall be delivered over native Ethernet-based Metro networks and could also be supported by other transport technologies. b. Carrier-class Ethernet-based metro transport technologies by specifying architecture, protocols and management for Ethernet-based metro transport networks The secondary priorities of the MEF are (when deemed necessary) to define: a. Work to be done by other organizations on other transport technologies (liaison activity) b. Non-Ethernet interfaces, if not defined by other organizations.
