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 - )
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

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

Hardware Costs • 10 Gbps Router Interface • Transmission Costs • Switched and Routed Architecture • 40 Gbps Interface
Is Speed Everything? • 40 Gbps Technology Cost • Multiple 2.5 Gbps or 10 Gbps wavelengths • Interfacing Costs • Routers • Switches
Technical Challenges • Enhanced Network Security • Role of DIY Transmission • New Architecture • Resource Allocation • Move from Connectivity to Controlability
Cost Challenges • Increasing Divergence of Costs • Transmission is Distance Dependent Cost • New Usage Patterns
Global Co-operation • Today Ad-Hoc Organisation • Question of Who Pays • Inter-Regional Organisation • Global Demand?
Summary • We are Deploying the Most Advanced Technology • Can we Control it? • Will we be able to Continue to Afford it?
