Characteristics of Today’s Business Applications

More business processes are automated

Require increasing amounts of capacity

Chattier – latency is an issue

Accessed by multiple constituents,

via multiple device types, from multiple geographies

Multiple delivery models – packaged software, SaaS, cloud

Complex data types comprised of voice, data and video

IT Challenge: Deliver Consistent Application Performance

1980‟s Applications

run on computers

2010‟s Applications

run on networks


Enterprise Network Demands: The bottom line

It‟s about Accessibility Downtime is unacceptable

It‟s about Your Business Applications Performance Assurance

• Business communications and operations must be treated as vital end-to-end

Application Persistence

• On-the-move session persistence

Visibility and Control

• Can‟t manage what cannot be seen

It‟s about Expense Predictability and Simplicity If not straightforward, lose a portion of the purported benefits

It‟s about Private Communications All networks are shared networks, but communications must remain private

The Global Ethernet Access Services Market

Ethernet is becoming the preferred

way for businesses to connect to the

network

Ethernet Delivers

Almost every application an end user

needs can be delivered over Ethernet

Web, E-mail, Storage, VoIP, Video

Conferencing, Streaming ….

Ethernet Access represents the

largest market opportunity

Ethernet is truly “Plug and Play”


Carrier EthernetCarrier Ethernet is a ubiquitous, standardized, carrier-class Service and Network

defined by five attributes that distinguish Carrier Ethernet from familiar LAN-based

Ethernet

Standardized Services

Scalability

Reliability

Quality of Service

Service Management

It provides native Ethernet packet access which presents a direct challenge to the

traditional SONET telephony infrastructure

It provides Wide Area networking scalable beyond 10Gbps using ubiquitous

Ethernet technology

Carrier Ethernet services include all layer 2 services sold under various names –

E-Line/E-LAN

Transparent or native LAN

Metro Ethernet

Ethernet private line (EPL)

Ethernet virtual private line (EVPL)

Layer 2 virtual private network (VPN)

Ethernet access

Virtual Private LAN Service (VPLS).


Developing Standards-BasedWholesale Ethernet Access Services

The standards for deploying Carrier Ethernet

Services are well defined

Metro Ethernet Forum

Current Carrier Ethernet Services

Improved geographic availability

More service offerings from more service providers

Carriers

LECs

Cable

Other MSOs

Service offerings are becoming more sophisticated and feature complete

Improved performance guarantees

Greater transparency options

MAC scaling

More users are switching from older packet-based technologies like Frame

Relay and ATM to MPLS and Ethernet

Large Enterprise, Wireless, Retail, Financials, Health Care, Energy, Manufacturing,

and more


Enhancing the User Experience

Ethernet has evolved from a „local‟ private network protocol to become part of the

WAN network

Carriers and equipment vendors need to adopt and implement standards to provide

the same level of OAM&P support that users have come to expect with any other

public telecom service

• Continuity check

• Link trace

• Loopback

One Connection Any Application

Businesses build

networks to support

their business

applications

Ethernet supports

connections to a

wide range of

services

Across our footprint Level 3 provides the same uniform service levels for

any of our services, switched or dedicated

Users can select the type of service they need based on the Service Levels

their applications require

Application performance is the key

Summary

Ethernet delivers almost any type of

service

There are three types of services –

E-Line, E-LAN and E-Tree

Ethernet services can be created with

multiple types of technologies – MPLS,

SONET, DWDM

Services should be selected based on

the requirements of your applications
