Why a High Leverage NetworkTM ?


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


From

… makes network transformation to all IP a necessity over time

Multiple “silo” networks Fixed, Internet, Mobile

Optimized for voice

“Dumb pipe”

“Walled Garden”

Scaling of bandwidth, users and devices is complex and expensive

Hierarchical, rigid, complex

High carbon foot print network

Converged network Common infrastructure that integrates

network layers where relevant

Supports multiple services Voice, video, high speed Internet

Intelligence distributed across the network to support advanced applications

Own and 3rd party applications & content

Scalable – continuous and cost-effective scaling of bandwidth, users and devices

Integrated, simpler-to-operate network

Lower power, eco-sustainable network

To

Reducing complexity, cost and time to service - Increasing revenue

Converged Backbone Transformation and its enablers2

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.
