5 MEF: Defining Body of Carrier Ethernet
174 Member Companies 78 Service Providers Global Representation Standards Education Compliance MEF Membership grew to 174 members, including 78 service providers and our first representatives from South America, the Caribbean and Africa – areas of “Market Development” focus for MEF; MEF specifications are being adopted globally and the work of the TC is the envy of the telecommunications industry. Global Interconnect moved to the forefront, with the launch of MEF 26 (ENNI), the emergence of Carrier Ethernet Exchanges and MEF’s Global Interconnect Program Program Focus : Global Interconnect

6 Five Attributes of Carrier Ethernet
Services – must support Translation of MEF EVPL, E-Line, E-LAN service types and profiles with multiple CoS Quality of Service – Service Monitoring Must support enforceable, measurable, end-to-end service (frame delay, delay variation, availability). Service Management – Process Integration Must support normalized process human and system for process transactions Reliability – Protection. Must provide protection: carrier class with geographical diversity A true Carrier Ethernet exchange must facilitate each of the 5 attributes of Carrier Ethernet Therefore, Carrier Ethernet Exchange, must interconnect Carrier Ethernet services with these five attributes Carrier Ethernet is defined by MEF as Ethernet plus five carrier-class attributes: Reliability; Standardized Services, Quality of Service, Service Management, Scalability Deliver on-net experience off-net Deliver scalable Carrier Ethernet interconnect worldwide for any Carrier Ethernet service location connecting to any other seamlessly, much like telephony services by today PSTN networks, but inclusive of data, voice and video, and operational in days not months Scalability – Scalability. Must support and access millions of EVCs and worldwide locations with scalable processes

7 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 (NNI) Between service provider internal networks (I-NNI) (For full presentation of Ethernet Services visit
