The Metro Ethernet Forum’s Mission
Accelerate the worldwide adoption of carrier-class Ethernet networks and services
1. Need and demand for a simple ubiquitous service2. Requirement to scale network services to enable rapid
deployment of applications3. Availability of low cost, high bandwidth of Ethernet,
beyond the LAN4. Convergence of business, residential and mobile
services

Carrier Ethernet Is Great!
… But What Do We Mean By “Ethernet”?
11
“Ethernet” – Different Points of View
• Ethernet as a point-to-point linkIEEE 802.3 view
• Ethernet as a packet switched network (PSN) infrastructure
IEEE 802.1 (bridging) viewITU-T SG15 / SG13 managed Ethernet network view
• Ethernet as a serviceMEF view – user-to-user transfer of 802.3 frames over any transport layer Think E-Line, E-LAN and (soon) E-Tree
12
Carrier Ethernet – Service Provider View
• A set of interconnected network elements transporting Carrier Ethernet services for all users, locally & worldwide
• Carrier Ethernet services are carried over physical Ethernet networks and other legacy transport technologies
13
Carrier Ethernet – User View
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
14
Attribute 1:Standardized Services
Carrier Ethernet is a ubiquitous, standardized, carrier-class SERVICE defined by five attributes that distinguish Carrier Ethernet from familiar LAN based Ethernet
The End Goal is Carrier Ethernet

Attribute 2:Scalability
Carrier Ethernet is a ubiquitous, standardized, carrier-class SERVICE defined by five attributes that distinguish Carrier Ethernet from familiar LAN based Ethernet
The End Goal is Carrier Ethernet
17
Standards Enable Scalability
Carrier Ethernet supports identical services over many physical media• Enterprise customers: Flexible business services• Residential customers – Scalable Triple Play Services• Mobile Carriers – Broadband data services (3G/4G/WiMax)Easily upgradeable; backwards compatible Several transport technologies add the notion of hierarchy to a Carrier Ethernet
network (like MPLS, PBB/PBB-TE, MPLS-TP) – enable large numbers of customers in a Carrier Ethernet network

Influence of OAM On Infrastructure Cost
• Ethernet vendors often advertise low investment (Capex) costs
• What about operational cost (Opex)?– Largest fraction of opex cost: Provisioning and
troubleshooting– Carriers cannot afford to field service the FTTx components
in the edge• Ethernet OAM (IEEE 802.1ag) eliminates field service
needs• Can be deployed across different types of technologies
used for Metro Ethernet Networks• Also assists in fast fault detection and isolation (leads to
reliability)
21
Standards Enable Service Management
– Performance Monitoring (ITU-T Y.1731)– Service OAM (CFM, IEEE 802.1ag)– Link OAM (EFM, IEEE 802.1ah)– E-LMI (MEF 16)

E-NNI Specification Editor: Steve Holmgren, at&t
• Nobody has footprint everywhere. The interconnection of Carrier Ethernet networks is one of the last hurdles for ubiquitous Ethernet services
• Need a common language for peering• E-NNI is a reference point representing the boundary between two Carrier Ethernet
Networks, each in a different administrative domain• Draft # 4 is the latest version; many comments pending
