Why a High Leverage Network TM ?

A demanding market reality for network providers… Cost Challenge Traffic Revenues Time Mainly voice Multimedia/multiservice ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Requires a change from keeping value in the network to extracting value from the network

… makes network transformation to all IP a necessity over time ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],From Reducing complexity, cost and time to service - Increasing revenue ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],To

Converged Backbone Transformation and its enablers 2

IP/Optical Backbone – The Status Quo The traditional approach does not cost effectively address traffic growth & service diversity IP/MPLS Network Management Optical Network Management Internet Data Center Data Center DWDM Nodes 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. Service Routers Service Routers

IP/Optical Backbone The HLN Converged Backbone Transformation solution approach Internet Data Center Data Center Reduces transport costs by over 30% Handles traffic at lowest layer via flexible grooming & IP offloading options Increases cross-layer visibility & coordination Management Plane Integration Seamless network visibility and provisioning across IP & optical domains IP/MPLS Network Management Optical Network Management IP/Optical Integration Core IP Routers Service Routers Service Routers Data Plane Integration 10/40/100G on Optics and IP Flexible grooming & offload options to maximize link utilization Control Plane Integration Increased cross-layer visibility and resiliency OTN/Photonic Switches
