3. 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 1.The need and demand for a simple ubiquitous service 2.Requirement to scale network services to enable rapid deployment of applications critical to enterprises and service providers. 3.Availability of low cost, high bandwidth Ethernet, beyond the LAN 4.Convergence of business, residential and wireless services

4. 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

5. 5 Carrier Ethernet Defined Carrier Ethernet for the Business Users: The MEF has defined Carrier Ethernet as A ubiquitous, standardized, carrier-class Service and Network defined by five attributes that distinguish it from familiar LAN based Ethernet

6. 6 Carrier Ethernet Defined A set of certified network elements that connect to transport Carrier Ethernet services for all users, locally & worldwide Carrier Ethernet services are carried over physical Ethernet networks and other legacy transport technologies Carrier Ethernet for Service Providers:

7. 7 The 5 Attributes Carrier Ethernet (1) Attribute 1: Standardized Services E-Line, E-LAN provide transparent, private line, virtual private line and multi-point to multi-point LAN services. A ubiquitous service providing globally & locally via standardized equipment Requires no changes to customer LAN equipment or networks and accommodates existing network connectivity such as, time-sensitive, TDM traffic and signaling Ideally suited to converged voice, video & data networks Wide choice and granularity of bandwidth and quality of service options

8. 8 The 5 Attributes Carrier Ethernet (2) The ability for millions to use a network service that is ideal for the widest variety of business, information, communications and entertainment applications with voice, video and data Spans Access & Metro to National & Global Services over a wide variety of physical infrastructures implemented by a wide range of Service Providers Scalability of bandwidth from 1Mbps to 10Gbps and beyond, in granular increments Attribute 2: Scalability

9. 9 The 5 Attributes Carrier Ethernet (3) Attribute 3: Reliability The ability for the network to detect & recover from incidents without impacting users Meeting the most demanding quality and availability requirements Rapid recovery time when problems do occur, as low as 50ms

10. 10 The 5 Attributes Carrier Ethernet (4) Wide choice and granularity of bandwidth and quality of service options Service Level Agreements (SLAs) that deliver end-to-end performance matching the requirements for voice, video and data over converged business and residential networks Provisioning via SLAs that provide end-to-end performance based on CIR, frame loss, delay and delay variation characteristics Attribute 4: Quality of Service

11. 11 The 5 Attributes Carrier Ethernet (5) Attribute 5: Service Management The ability to monitor, diagnose and centrally manage the network, using standards-based vendor independent implementations Carrier-class OAM Rapid service provisioning
