Why a High Leverage NetworkTM ?
5 | “Redes troncales” | Sept 2010 © Alcatel-Lucent 2010
A demanding market reality for network providers…
Cost Challenge
Traffic
Revenues
Time
Mainlyvoice
Multimedia/multiservice
Video and content rich services are booming…Affordable broadband, proliferation of smart devices, multiplicity of multimedia/video applications
… but users expect more…Simple, personalized access and interaction,across any device, any network, anytime, anywhere
… and access to 3rd party apps & contentPaid for by advertisers, free to end-users – network providers extract limited value
Requires a change from keeping value in the network to extracting value from the network

Core IP Routers
Virtually all traffic traverses multiple core routers. Many are being upgraded
at significant cost.
Service providers are facing the challenges of video traffic growth and expanded service diversity that is straining traditional core router and
transport networks
Unnecessary packet processing by core routers.
Inefficient utilization of interconnect ports forces unnecessary core router upgrades.
