  1. Media Networking Per Lindgren,VP Business Developmentper.lindgren@netinsight.net

  2. voice The vision is the challenge Our vision is that the need for video and other real time sensitive media will grow rapidly in the future. This poses new and significant challenges for network solutions. media data Net Insight is based on research conducted at The Swedish Royal Institute of Technology (KTH) – The misison was to find the solutions for next generation, media rich, networking. The research was partly sponsored by Ericsson and Telia.

  3. TV DTM channel A - ISP 1 lx Video IP Classes of service IP IP IP IP DTM channel B - ISP 2 (best effort) Data web IP IP IP IP IP IP IP IP IP DTM channel C - PTT 1 Voice Multiservice with 100% QoS at full network load Resource management in optical domain ensures service separation • Service separation ensures 100% QoS • Service separation ensures high utilization

  4. 1. Market Trends and Network Development - Media networks - Satellite benchmarking

  5. Video/Media market expansion - Win-Win B2B media contribution Content Delivery Networks (CDN) B2C Content Distribution Networks • Operators • End customer need today • Large investments made in optical infrastructure - need revenue generating traffic to fill it • New market segment opportunity with high growth and short RoI • Media customers • Complement costly satellite transport • Higher quality in production and reduced production time

  6. Benchmarking US media Pricing Satellite pricing: 32 Mbps satellite connection $200 000/month Point-to-point: 32 Mbps occasional production $6000/month N.Y. – D.C $70 000/month L.A. – N.Y. Net Insight’s solution in combination with the low cost of fibre capacity makes it possible to price a service at 50 % of above prices and still have payback in less than 12 months.

  7. 2. Professional Media and Entertainment industry Media networking (streaming) - Services: SDI/SDTI/ASI/GigE - Media applications - CATV/CDN distribution

  8. Services enabled • High speed real time streaming services with 100 % QoS, • Occaisionally, scheduled or permanent service • Services: • SDI 270 Mbps Streaming • DVB-ASI 0,5-220 Mbps Streaming • IP MPEG Streaming • Lan to Lan • Voice VPN’s • Multicast or broadcast of video streams • Up to eight uncompressed SDI streams/OC-48

  9. Saturday: Football match Sunday: Shooting Soap Opera Broadcast to TV tower via DVB-ASI Request film via IP Recieve film via SDI 3. Service offering example -Video production STADIUM CITY HALL Wide Media Network STUDIO BT.601 FILM BANKS Editing unit

  11. Head-End Head-End Head-End National content distribution networks Low delay and mulitcast enables nation-wide CDN networks Access Hubs MasterHead-end STM-1 STM-4 STM-16 Head-End Head-End 29x .. 29x • Gigabit Ethernet for interactive data • DVB-ASI for video • DVB-ASI Multicast • Low delay - no jitter • Less local equipment OC-48/DWDM HeadEnd

  12. 3. Media networking requirements • Reliability - Redundancy • Guaranteed QoS - Real-time • On-demand delivery • High capacity • over existing infrastructure

  13. Telecom and Media do not talk • Access interfaces often telecom, not media oriented • Reliability is key!!! • High end video today not economically feasible • Store and forward of large files has to be combined with live real-time streaming - in the same infrastructure! • Provisioning often very static • Problems with jitter/wander and delay over existing networks

  14. Customer acknowledgement “MPEG transport over IP or ATM is simply not the ideal outcome - they are not suited to this application”. “This is why we are so excited about DTM which is designed for this sort of high-value simplex, synchronous traffic” Andy Setos, Executive Vice President of the News Technology Group, Fox Television. TV Technology Magazine, Sept. 5, 2001

  15. Broadband networking of today Synchronous TDM Packet Switching SDH/SONET ATM Gigabit Ethernet Guaranteed Service High reliability High utilization Flexibility Best of both worlds neededGuaranteed QoS Dynamic Provisioning Simple and flexible SLAs Real-time support Traffic Engineering

  16. Our vision of next generation optical networking • IP is already the general purpose service interface • Ethernet will be the datacom interface • SDI, SDTI, ASI and Gigabit Ethernet are the media interfaces • Sonet/SDH is the legacy transport technology for fibre based networks DWDM transport • TDM based canalisation enable 100%QoS, provisioning and SLA (billing) support for both streaming and datacom services Applications GMPLS ? Ethernet / IP PDH SDI / ASI TDM based canalization Sonet / SDH Fiber / DWDM

  17. Conclusion • Era of media and telecommunications convergence - win-win situation • Operators need new services for competitive edge • Media companies can rationalize production and create new business • Streaming - a killer application to current networks • DTM - First optical standard for effective resource management over DWDM - March 01
