  1. Broadcasters and NREN’s: an interesting combination

  2. Issues addressed • The rationale behind connecting broadcasters • Broadcasting organizations connected to SURFnet • NREN-services provided to broadcasters • Lessons learned from connecting broadcasters • Future developments

  3. The rationale Broadcasters (national and regional) are:  publicly funded (Ministry of Education, Culture & Science (except for commercial broadcasters!)  focused on innovation  interesting content providers

  4. SURFnet connects: • Dutch National Public Broadcasting Organization • Beeld & Geluid (archive with 700.000 hours of material) • Eight regional public broadcasting organizations

  5. Mediagateway Beeld & Geluid: Storage, archiving & distribution

  6. Regional (public) broadcasters connected SURFnet currently connects 8 (of 14) regional public broadcasters

  7. Services provided • Infrastructure: • Network capacity (1G or 10G IP) • Network availability • Multicast support (live video) • Lightpaths for storage/archiving • - SURFmedia (video on demand)

  8. What is SURFmedia? 8 SURFnet, grensverleggend netwerk voor hoger onderwijs en onderzoek Video distribution platform for content providers (universities, publishers, broadcasters etc.) Uploading and viewing available for end-users (including students) of all connected institutions Connected to the SURFfederation and SURFgroepen (authentication & authorization) Back-end: SURFmediacore

  9. SURFmedia Functionality 9 SURFnet, grensverleggend netwerk voor hoger onderwijs en onderzoek • End-user: • Search for content • View Flash previews • Review / tag material • Create collections • Content provider: • Upload Windows Media, MPEG-4 en Flash • HD supported as well • Live TV channels available • Manage content • Access restrictions, based on realm

  10. SURFmedia SURFnet, grensverleggend netwerk voor hoger onderwijs en onderzoek

  11. SURFmedia Facilitates inclusion of audio en video content for educational purposes http://www.surfmedia.nl

  12. Focus on institutions Tariff model based on disk-space in use Focus on end-users No costs incurred for end-users

  13. Lessons learned • Broadcasting landscape in flux: • Public versus commercial • National versus regional versus local • Broadcasters require a range of services: • IP-transit to higher education and research institutions + end-users • IP-transit to “rest of the world” • Storage and archiving (lightpaths) • Distribution of streaming and live content (multicast, mediaplatform) • Live events can generate huge traffic volumes

  14. Lessons learned • Contract model: • connection available for public broadcasters only (acceptable user policy) • standard contract conditions for traffic to/from higher education • fair-use conditions for traffic to/from “rest of the world” • acceptable use policy for end-users • Tariff model: • End-user accounts are standard 1 GB • Additional disk-space available on request of institution • Additional disk-space charged per extra GB/TB

  15. Future : Content Delivery Network (CDN)  Specs Dutch (broadcasting) CDN: • Decentralised video-distribution • Video-servers located at ISP’s • Initiative coordinated by AMS-IX • Inducement: Tour de France 2008 • 48.000 concurrent viewers created a bit-stream of 40 Gbit/s. Infrastructure scaled to max. 30.000 viewers! • Implementation: • Optimise network & server usage • Pro-active replication technology SURFnet, grensverleggend netwerk voor hoger onderwijs en onderzoek
