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

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)

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

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
