3. 3 Copyright © 2006 Juniper Networks, Inc. Proprietary and Confidentialwww.juniper.net IPTV Opportunity vs. Risks  Clear Opportunity exist to add Video to the existing Voice and Data Services Expand share of wallet These help differentiate service offerings, add subs, and lower churn  IPTV still in its infancy <2M lines deployed,30M-50M projected in 5 years (Source: Telephony Magazine) Presents an opportunity to lead the Market  Competing against Other Video Sources (Cable, Satellite, Internet) No Differentiation is a recipe for disaster More importantly cost of delivering the service in an economical viable way

4. 4 Copyright © 2006 Juniper Networks, Inc. Proprietary and Confidentialwww.juniper.net IPTV and Beyond … IPTV is just one Service  Red = “Triple Play”  Blue = Service differentiator and opportunities for incremental revenue  Choose an architecture that allows rapid intro of any of these services !

5. 5 Copyright © 2006 Juniper Networks, Inc. Proprietary and Confidentialwww.juniper.net What Creates Costs in Network?  Network complexity is created by: Forecasts and number of customers Number of boxes and facilities Number of different boxes Number of required upgrades and installations Reliability and performance Complexity of provisioning and customer care process  Complexity results in increases in both CAPEX and OPEX: Facilities costs Customer care headcount NOC Headcount Training and other costs

Proprietary and Confidentialwww.juniper.net Subscriber Benefits Full access to all available bandwidth QoS for all services Provider Benefits: Eliminates need to statically partition bandwidth per service Minimizes planning and provisioning associated with rollout of IPTV Dynamic Bandwidth Allocation: Bandwidth, Where and When it’s Needed VOIP IP Video Data Internet Port IPTV VoIP Video/Hub Serving Office Video Head-end Office Video Hub Office Policy Manager Customer VLAN shaped to 10Mbps service Before IPTV is turned on – bandwidth fully allocated to Data/Voice Upon IPTV activation – Broadband Services Router adjusts BW to ensure IPTV QoE, Voice / Data allocated remaining bandwidth RG

12. 12 Copyright © 2006 Juniper Networks, Inc. Proprietary and Confidentialwww.juniper.net Static ‘Carve Out’ Models: Bandwidth, Whether it’s Needed or Not Internet Port IPTV VoD High-speed Internet Broadcast video Video On Demand RG  Complex/Static provisioning on a per-service basis = Big OPEX $$ What happens when there is a shift to HDTV? What happens when a new service is introduced? Migration path to interactive services?  Using a VLAN/VC per service prevents resource sharing

13. 13 Copyright © 2006 Juniper Networks, Inc. Proprietary and Confidentialwww.juniper.net Internet Port IPTV VoD High-speed Internet Broadcast video Video On Demand RG Network Architecture is Critical Dynamic Bandwidth Allocation between services works because………  A single converged network for all services  Common Service Delivery Point (SDP) provides ability to share resources  Auto Provisioning – zero touch too add new services and customers  Simplifies Access Aggregation by centralizing complex tasks

14. 14 Copyright © 2006 Juniper Networks, Inc. Proprietary and Confidentialwww.juniper.net Operational Cost Savings Assumes $12 cost to carrier to provision a service connection (not including ADSL connections) and shows the impact of cutting connection requests in half In the highest growth years this represents a $12.5M savings

Proprietary and Confidentialwww.juniper.net Any Service, Any Access  “Agnostic to Access Method” ADSL, ADSL2+, VDSL, FTTN, FTTP (APON, GPON), WiMax Access technologies will continue to evolve, physical plant deployments should not impede service delivery Intelligence is separate from the physical plant and its upgrades  Invest in infrastructure which builds a framework for scalable and extensible service deployments  A solution that works for residential, small business and large enterprise

16. 16 Copyright © 2006 Juniper Networks, Inc. Proprietary and Confidentialwww.juniper.net Summary  Choosing the right network architecture has far- reaching impact on cost and ensuing success of IPTV service  High-speed Internet Access remains critically important….it’s an early adopter base for IPTV service  A few Customers who chosen Juniper to be the “IP” in their IPTV services
