E-LAN service types and profiles with multiple CoS

Quality of ServiceService Monitoring

Must support enforceable, measurable, end-to-end service

(frame delay, delay variation, availability).

ReliabilityProtection. Must provide protection: carrier

class with geographical diversity

Service ManagementProcess IntegrationMust support normalized process human and system for

process transactions

ScalabilityScalability. Must support and access millions

of EVCs and worldwide locations with scalable processes

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)

Bandwidth Profiles & Traffic Management

Bandwidth Profiles per EVC (service) and per CoS

CIR (Committed Information Rate)

CIR assured via Bandwidth Reservation and TrafficEngineering

EIR (Excess Information Rate)

EIR bandwidth is considered excess

Traffic dropped at congestion points in the network

CBS/EBS (Committed/Excess Burst Size)

Higher burst size results in improved performance

Related MEF Services Specifications

Purpose Defines the Ethernet Services (EPL, EVPL, E-Line, ELAN, and E-Tree)

MEF 6.1

Purpose

Defines the service attributes and parameters required to offer the services

defined in MEF 6. Updated from Original MEF 10 in October 2006

Audience

Appropriate for equipment vendors, service providers, and business

customers, since it provides the fundamentals required to build devices

and services that deliver Carrier Ethernet. For Enterprise users it gives the

background to Service Level Specifications for Carrier Ethernet Services

being offered by their Service Providers and helps to plan Ethernet

Services as part of their overall network.

Buyer Benefits

Reduce operating costs

Through aggregation and inter-operability of multiple Carrier Ethernet services

over a single standards-based physical connection

Reduce capital costs

Through use of logical connections instead of capital intensive physical assets

(e.g. POPs, circuits, etc.)

Increase footprintand reach larger and/or new markets

Geographic (e.g. emerging markets, regional markets)

Capacity (e.g. 1 GbE, 10 GbE)

Capability to address new market segments (e.g. residential, enterprise, etc.)

Reduce time to market and improvefinancial benefits

Building a standardized ENNI is faster than building out proprietary

infrastructure

Quicker recognition of internal SP infrastructure projects financialbenefits

Increase business efficiencies

Lower management costs through proven inter-operability

processes (ordering, implementation, operations, billing)


23/26

23

Seller Benefits

Reduce operating costs

Spreading fixed operating costs over a large number of inter-operable, standards-

based virtual connections

Reduce capital costs

Faster amortization of initial investment through larger number of virtual

connections

Defend footprint

By providing efficient access to sellers footprint under seller SP commercial terms Reduce time to market and improvefinancial benefits

More efficient sales distribution channel using ENNIs instead of multiple EPLs

Enables faster revenue recognition from retail customers

Increase business efficiencies

Through standardized ENNI fulfillment and repair processes

Summary

Implementation of Carrier Ethernet Global Interconnects worldwide

with continued acceleration in 2011 and beyond

MEF Global Interconnect Program, consisting of MEF Specifications,

Certification and Connect, provides a common and standard

framework for the industry

Collectively, Global Interconnect exists to enable standardizedand streamlined delivery of MEF-certified Carrier Ethernet

services to scale locally and globally:

For end users the worldwide connection is transparent and seamless.

For service providers it unlocks new revenue opportunities: expanding the

numbers of locations that can be reached economically
