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

6. 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

7. The 5 Attributes Carrier Ethernet (2) Attribute 2:Scalability • 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

8. 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

9. The 5 Attributes Carrier Ethernet (4) Attribute 4:Quality of Service • 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

10. 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

11. Carrier Ethernet Terminology • UNI (User-to-Network Interface) • Physical interface/demarcation between service provider and subscriber • Service start/end point • Ethernet Virtual Connection (EVC) • An association of two or more UNIs • Three types of EVC • Point-to-Point • Multipoint-to-Multipoint • Rooted Multipoint (Point-to-Multipoint) • EVCs and Services In a Carrier Ethernet network, data is transported across Point-to-Point, Point-to-Multipoint and Multipoint-to-Multipoint EVCs according to the attributes and definitions of the E-Line and E-LAN services • NNI (Network-to-Network Interface) • Demarcation/peering point • Between service providers (ENNI) • Between service provider internal networks (I-NNI)

12. Transforming Carrier Ethernet

46. Part of International Standards Community Working outward from the core Working inward from the edge Making it work together The MEF’s role is largely additive to these organizations, developing necessary additional specifications that are required to enable Carrier Ethernet. The MEF also provides inputs in support of Carrier Ethernet to these bodies via its participating members and liaisons. It is not within the scope of the MEF to endorse or otherwise the work of other standards bodies and associations

47. Complementary Standards Activities • Goals • Reach consensus, bring MEF work to other bodies, re-use work of other bodies, work with other bodies, avoid duplication, keep in communications Scalability IEEE Provider Bridge IEEE 802.1ad Provider Backbone Bridge IEEE 802.1ah (MAC-in-MAC, and extended label space) ITU-T ITU-T SG 15 has referenced the MEF service work in their documents that describe EPL and EVPL.
