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

• Allows provider equipment to provision, configure and distribute EVC information and attributes to customer equipment.

• Allows customer equipment to retrieve EVC status and configuration information from service provider equipment.

• Adds fault management and protection functionalities beyond those specified in UNI Type 1.
