Broadcasters and NREN’s:
an interesting combination
20-7-2017
Issues addressed
- The rationale behind connecting broadcasters
- Broadcasting organizations connected to SURFnet
- NREN-services provided to broadcasters
- Lessons learned from connecting broadcasters
- Future developments
The rationale
Broadcasters (national and regional) are:
&
publicly funded (Ministry of Education, Culture
Science (except for commercial broadcasters!)
focused on innovation

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
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
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
