  2. NORDUnet’s Mission and Activities • Mission • International service provider for the Nordic national networks for research and education • Nordic platform for • International research networking • Network development • Activities • Research networking • Network development • Provision of General Internet connectivity NORDUnet 2003 1

  3. NORDUnet organisation • Danish limited company • Shareholders are the Nordic states or state institutions • DK - Ministry of Science • FI - Ministry of Education • IS - University of Iceland • NO - UNINETT • SE - National Agency for Higher Education • Board members are managers of the Nordic national networks for research and education • Financed by the Nordic national networks with GNP based cost sharing NORDUnet 2003 2

  9. General Internet Service • The General Internet Service is the connectivity between the Nordic research networks and the General Internet. • NORDUnet provides it in two ways • Peering with IP providers, mainly in Stockholm (20% of traffic) • Purchase of IP Transit from IP providers (80% of traffic) • Earlier, NORDUnet connected to IP providers in USA and used its own transatlantic links, but in 2001 it was changed to a local connection in Stockholm to KPNQwest’s IP network, because • it was cheaper, being at the beginning of a dramatic price decrease of IP transit services • it was technically safer, because of more physical redundancy in the networks NORDUnet 2003 8

  10. but ……. • it turned out to be extremely unsafe because of the lack of viability of the provider • On 31 May 2002 KPNQwest filed for bankruptcy and the fate of the 2Gbit/s service became uncertain • However, NORDUnet was lucky because a 2.5G backup connection under implementation to KPNQwest in Copenhagen could be connected to Sprint International in Copenhagen within a few days and became operational on 30 May 2002as the KPNQwest troubles were anticipated some time before the bankruptcy • and on 6 June another 2.5G connection was set up to Telia in Stockholm with the local loop delivered in 7 days • As a result continuity of service was assured, and NORDUnet could use the rest of the year to normalise the service situation by issuing a new call for tender NORDUnet 2003 9

  11. and today ….. • NORDUnet has learned the lesson and has two providers of IP transit service, each connected over two 2.5G ports (3 ports in Stockholm and 1 port in Copenhagen) • The arrangement gives local and global physical redundancy, as well as fall-back options in case of commercial trouble NORDUnet 2003 10

  12. Connection to USA research • October 1988: 56 Kbit/s satellite link to Princeton • 1991-1997: NSF ICM programme • From 128K to 50M • 1999-2003: NSF HPIIS programme • Separate commercial and research connectivity • Connect to Startap • August 2003: Terminate NORDUnet’s own 622M link to USA and use GÉANT for the services, because • GÉANT has become well connected to USA networks • Abilene provides intercontinental transit • service is embedded in GÉANT subscription fee • A big Thank You from NORDUnet to NSF, Abilene, ESnet, vBNS, Canarie and SINET, for this long-lasting direct connection NORDUnet 2003 11

  13. Forskningsnet • Upgrading from 622Mbit/s to a 2.5 Gbit/s ring structure: • Copenhagen-Odense-Århus-Aalborg- and back via Göteborg to Copenhagen • Network research • setting up a Danish national IPv6 activity • dark fibre through the country • GE channels • experimental equipment for 10GE channels • No central funding in 2003 NORDUnet 2003 12

  14. FUNET • Business as usual (upgraded to 2.5G already at previous conference begin 2002) • Accesses upgraded form 155M to 622M and GE • Upgrading backbone routers to 10G capability NORDUnet 2003 13

  15. RHnet • GE ring in the Reykjavik area and 10-100M links to outside • NORDUnet connection over CANTAT-3 sea cable upgraded to 155M in Jan 2003 • No back up of NORDUnet connection • RHnet back as Iceland member of Terena • No central funding NORDUnet 2003 14

  16. UNINETT • Network upgraded to 2.5G between major universities, based on a 15 year IRU with cost based further upgrades • FEIDE middleware project progress towards a common electronic identity towards different services. Collaborate with the Nordic GNOMIS initiative • UNINETT is expanding to more services and organisations: • UNINETT and NTNU collaborate in centre of excellence: “Centre for Quantifiable Quality of Service in Communications Systems” (Q2S). 35 scientists for next 10 years. • A subsidiary, UNINETT ABC, has been tasked by government to define strategy and architecture and operational solutions for networking schools in Norway • UNINETT and SINTEF will set up a national centre for Information Security NORDUnet 2003 15

  17. SUNET • 10G resilient nationwide network since Nov 2002 • all 32 universities have 2.5G access • End-to-end performance between GE ports over production IP networks : • 960Mbit/s over 1000 km SUNET in Sweden • 970Mbit/s over 14600 km SUNET-Sprintlink between SUNET and Sprint at San Jose • Production type support for netbased meetings • Active participation in SweGrid, Swedish Grid Initiative • Launched extensive study of actual usages of SUNET • user interviews • technical measurements NORDUnet 2003 16

  18. IPv6 - 6NET 6NET backbone 155 Mbit/s Europe NORDUnet 2003 17

  19. Upgrade to 10 Gbit/s • Why 10G now? • SUNET backbone is 10G • Other Nordic networks are upgrading • GÉANT is 10G • NORDUnet must not be a bottleneck • GRIDs are coming • But ….. • 10G equipment is expensive • Cost includes one time investment that puts high demands on NORDUnet’s cash flow • So ….. • Spread the upgrade over 2 years to alleviate effect on cash flow • Backup at 5G only to reduce new equipment cost NORDUnet 2003 18

  23. NORDUnet “lambda” actions • Events • StarLight and NetherLight developments with European participation by SURFnet, CERN, CSnet, UKERNA • GARDEN project proposal • GRID users’ demands • NORDUnet (alias Nordic network research) wants to participate in developing this technology, and NORDUnet will • build a Nordic “lambda” infrastructure • connect it to NetherLight in Amsterdam • use it for 6NET and GARDEN, too NORDUnet 2003 22

  30. Trends • Research networking: • build for peak load • use GÉANT for intercontinental connectivity • Network development: • increase activities • act as Nordic platform • General Internet connectivity: • beware of provision stability • traffic growth flattening out? • Prepare for the GRID NORDUnet 2003 29
