What is the Service Edge?
The edge of a converged network where IP/MPLS services are provisioned:
Has a full range of access-facing interfaces to support multiple legacy and
IP/MPLS services over a converged backbone
Differentiates and manages thousands of unique services with wide
variations in QoS policy
Authenticates, authorizes and generates accounting data for subscribers of
high-speed Internet and IPTV services

“As the point from which IP/MPLS-based services are provisioned, the multi-service
edge is one of the most critical areas of investment.” Mark Bieberich, Yankee Group

All Rights Reserved © Alcatel-Lucent 2007
What is Service Aggregation?
A cost-effective response to the new requirements of
bandwidth-hungry services
Massive increase in bandwidth for video (triple play, mobile TV)
Broadcast television needs constant bandwidth
Video on demand, mobile TV, mobile music and
other applications will only increase total bandwidth
An SLA-based solution for Ethernet business
services
Ethernet economics and bandwidth
MPLS stability, scaling and service richness
Service aggregation reduces facilities cost without compromising SLA guarantees
