The Changing Services Landscape
Business Subscriber
Residential Subscriber
Hosted VoIP driving QoS
requirements on WAN links as
well as the carrier network
Providers expanding services to
compete for subscribers and
increase revenue
Businesses demand guaranteed
multi-site connectivity
Residential subscribers demand
guaranteed content and
telephony services
“Best-effort” Ethernet service is no longer sufficient.

Critical Success Factors
Service providers must leverage existing investment
in network infrastructure
Service portfolio must deliver the triple play
• Infrastructure must support Quality of Service
Ethernet and IP network must be carrier-class in
terms of resiliency and scalability
• Network and service resiliency
• Global scalability
Service providers and equipment vendors must form
business partnerships

Multi-Dimensional Ethernet
Essential for Carrier Ethernet Growth
Adding multiple dimensions to
Ethernet to deliver:
40 X
8X
4000 X more
Larger Scale
Lower Cost
Ethernet VPNs
Compared to the
past attempts at
offering service
guarantees per

Compared to
using routers to
connect to
multiple service
networks
Compared to
