OverviewOverview

• Ethernet transport is a key enabler for Ethernet (& IP) services– Uniquely meets most stringent service requirements– Improve service coverage and time to market– Accommodates today’s transport infrastructure and enables for

future migration

• Key applications in– Residential triple play backbones– Wireless access/backhaul– Data center networking– Resilient access to switched/routed data services networks

Un-answered Questions…Un-answered Questions…

• How to manage on an end-to-end basis• Sophisticated distributed traffic management vs.

Simple centralized traffic management• Converged Multi-service Packet Transport vs.

Separate Overlays for Packet and Circuit• Business services vs. Residential services – can

the same network converge both?• How do we serve the off-fiber customer?• What is the role of RPR? of MPLS?• How far should the Ethernet network go trying to

mimic the SONET/SDH operational model?

Alternative technologies that meet Carrier Ethernet standards can reliably bridge the gap

End users have a problem

Rising demand for bandwidth

Business trends such as VoIP, security, video, network backup and hosted applications are driving demand

Residential multimedia trends - broadband access, gaming, VoIP, IPTV driving demand

Service providers have a problem

Not Enough Access Fiber A significant amount of deployed fiber

infrastructure in the core is dark Fiber reaches only a small percentage

of customers today It is very expensive and slow to extend

fiber to the premises

Choosing the Right Access Technology to Bridge the GapChoosing the Right Access Technology to Bridge the Gap

Many factors determine which technology is right for each application– Cost– Bandwidth– Reliability– Speed to installation and service turn up

Compliance with Carrier Ethernet attributes like bandwidth Scalability and Protectionensures customer expectations are met regardless of the access technology chosen

xDSL2-40 Mbps

LAN10-100 Mbps

Technology Choices

Wireless Fiber Copper BPL

Access TechnologiesAccess Technologies

Fiber– Supports up to 10Gbps, highly reliable

– Fiber access is limited and trenching laterals can require substantial time and monetary investment

Copper– Leverages existing infrastructure

– Has bandwidth limitations

Wireless (Optical & RF)– RF Wireless (WiFi, WiMAX) solutions offer good

reach and up to 50Mbps– Optical wireless can offer good reach and up to

10Gbps– Meshing capabilities increase scalability and

protection
