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 • <2 M lines deployed, 30 M-50 M 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 Copyright © 2006 Juniper Networks, Inc.

IPTV and Beyond … IPTV is just one Service Potential Multi-Play Services Latency/Loss Sensitivity The Triple Play Video Conferencing/Telephony Voice Video PC-based Streaming Video Home Surveillance Broadband IM (PC or STB) Console Gaming Secure Internet Turbo button internet Music Download Game Download Video Download Bandwidth Consumption § Red = “Triple Play” § Blue = Service differentiator and opportunities for incremental revenue § Choose an architecture that allows rapid intro of any of these services !

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 Copyright © 2006 Juniper Networks, Inc.

Customer Service and Provisioning • Customer VLANs enable: Single Edge Approach Internet Port IPTV DSLAM ISP (Internet) CVLANs Switch Vo. IP IP Backbone Video Head End or ASP (e. g. IP Telephony) Multi-Edge Approach ISP (Internet) Internet IPTV Port Vo. IP Copyright © 2006 Juniper Networks, Inc. DSLAM Service VLANs Video Head End or ASP (e. g. IP Telephony) • Service Pre-Provisioned thereby minimizing call to customer care • Application integration at layer 3 with SDX • Bandwidth sharing across applications • Easy addition of new applications such as business services • Service VLANs Require • A device per service • Application integration at higher layers in the OSI stack (significant development by vendors) • Significant additional customer care costs • Effect will be (5 x number of service Connections) • Higher service provisioning and customer care • Higher application and future service deployment costs • Possible reduction in revenue due to limited add-on applications Proprietary and Confidential www. juniper. net 8

Dynamic Bandwidth Allocation: Bandwidth, Where and When it’s Needed Upon IPTV activation – Broadband Services Router adjusts BW to ensure IPTV Qo. E, Before IPTV is turned / Data fully allocated on Voice – bandwidth remaining bandwidth allocated to Data/Voice Video Head-end Office Video/Hub Serving Office Video Hub Office VOIP IP Video Data Policy Manager Internet Port IPTV RG Vo. IP Copyright © 2006 Juniper Networks, Inc. Customer VLAN shaped to 10 Mbps service Subscriber Benefits • Full access to all available bandwidth • Qo. S for all services Provider Benefits: • Eliminates need to statically partition bandwidth per service • Minimizes planning and provisioning associated with rollout of IPTV Proprietary and Confidential www. juniper. net 11

Static ‘Carve Out’ Models: Bandwidth, Whether it’s Needed or Not § 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 Internet Port prevents resource sharing IPTV High-speed Internet Broadcast video Video On Demand RG Vo.

Network Architecture is Critical Dynamic Bandwidth Allocation between services works because……… High-speed Internet § 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 Broadcast video Video On Demand Internet Port IPTV RG Vo.

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. 5 M savings Copyright © 2006 Juniper Networks, Inc. Proprietary and Confidential www. juniper. net 14

Any Service, Any Access § “Agnostic to Access Method” • ADSL, ADSL 2+, VDSL, FTTN, FTTP (APON, GPON), Wi. Max • 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 Copyright © 2006 Juniper Networks, Inc.

Summary § Choosing the right network architecture has farreaching 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 Copyright © 2006 Juniper Networks, Inc.
