  1. Future Directions in Research Networking - A Perspective from Europe 16th APAN MeetingAdvanced Network ConferenceBusan KoreaAugust 2003 Dai Davies : General Manager : DANTE Ltd dai.davies@dante.org.uk www.dante.net

  2. The Ages of European Research Networking • The Pioneering Age (1980 - 1988) • The Rationing Age (1988 - 1996) • The Co-operation Age (1996 - 2001) • The Age of the GÉANT (2001 - )

  3. Technology Available 1991-2002 Period Most performant Data Technology Available Technology Available Link Technology in pan-European in United States Available Network Network 1991 - 1995 34/45 Mbps PDH 2 Mbps PDH 45 Mbps PDH 1996 - 1997 155 Mbps SDH 45 Mbps PDH 155 Mbps SDH 1997 - 2000 622 Mbps SDH 155 Mbps SDH 622 Mbps SDH 2000 + 10 Gbps DWDM 10 Gbps DWDM 2.5 Gbps DWDM

  4. Price Trends pan-European Connectivity 1000000 100000 10000 average offer price 1000 lowest offer price 100 10 1 1996 1997 1998-9 1999-2000 2000-01 2002

  5. GÉANT Topology June 2003

  6. GÉANT • Huge Increase in Network Capacity • TEN-155 3 Gbps • GÉANT 150 Gbps • 9 “10 Gbps” Accesses • 20 Gbps Global Interconnection • Regional Initiatives • Mediterranean • Latin America

  7. GÉANT Issues • Divergence of Costs • New Usage patterns • Hardware Costs • Global Developments

  8. Divergence of Costs 45 40 35 30 25 1996 1999 2002 20 15 10 5 0 Range of Shared Costs Range of Connectivity Smoothing of Shared Costs

  9. Support for European VLBI Radio Telescope Correlator Data Flows (RT or non-RT)

  10. NORDUnet JANET SURFnet PSNC DFN GARR EVN Traffic Flows over GÉANT SE UK JIVE PL CZ BE NL DE2 DE1 FR CH AT 256M 512M ? 1G  2.5G 10G IT

  11. Hardware Costs • 10 Gbps Router Interface • Transmission Costs • Switched and Routed Architecture • 40 Gbps Interface

  12. Europe - Where Next...….?

  13. Is Speed Everything? • 40 Gbps Technology Cost • Multiple 2.5 Gbps or 10 Gbps wavelengths • Interfacing Costs • Routers • Switches

  14. Technical Challenges • Enhanced Network Security • Role of DIY Transmission • New Architecture • Resource Allocation • Move from Connectivity to Controlability

  15. Cost Challenges • Increasing Divergence of Costs • Transmission is Distance Dependent Cost • New Usage Patterns

  16. DWDM Cost Data

  17. Global Co-operation • Today Ad-Hoc Organisation • Question of Who Pays • Inter-Regional Organisation • Global Demand?

  18. Summary • We are Deploying the Most Advanced Technology • Can we Control it? • Will we be able to Continue to Afford it?
