Financial Arrangements
• EC support for Geant successor• Integrated Project
– Network Infrastructure– Developmental Elements
• Funded by the NRENS and the EC• Framework Programme 6 (FP6)
Extending the Range of Connections
• Initiatives to improve connectivity with other world regions -–Principally Mediterranean, South America and Asia Pacific
• Global Connectivity for joint network experimentation
• E.g. Russia will be upgraded from current 622Mbps to 2.5Gbps to Moscow
EC & NREN funded
• 186 MEuro over 4 years–Starting end 2004
• 93 Meuro available from EC• 93 MEuro payable by NRENs
–assuming 50% co-funding–Subscriptions are based on Bandwidth contracted for
Example Subscription
• E.g. under Geant /GN-1 HEAnet pays approx 900KEuro for dual 2.5Gbps , linked to London and Frankfurt
• Subscriptions range from ca. 1.5MEuro to 4MEuro in non competitively developed regions
• Currently Geant international 10Gbps widely available in Western Europe for under 2MEuro
• 50% Rebated by EC after Claims by Dante

Relativecost Trend Line
Some indications from Market in Europe
• 40Gbps not widely commercially available
• Cost of Interfaces for 40Gbps v. high
• Multiple 10Gbps may be more flexible solution
• Would allow Hybrid Network–Mix of IP and non-IP–Terminate on Routers and Switches

Some exciting possibilities
• Tender shows Charges for 10Gbps Lambdas are still reducing
• Additional Wavelengths will be even cheaper
• Multiple , dual-homed 10Gbps affordable in a number of locations
• 10Gbps Lambda possible building block
• Provide switched GEs to high-end users
Hybrid Infrastructure solution ?
• Enable to present to users, combination of point-to-point and IP services
• Interesting Technical Challenge !

Offers by Country
Series1
Managed Wavelengths and Dark Fibre
• Whether to invest in dark fibre IRUs and transmission equipment/management and maintenance
• In terms of costs -–May not be advantage in Western Europe
–Less competitive markets : more offers of dark fibre in Central and Eastern Europe
BASIC PROCUREMENT SEGMENTATION
• Major Pan-European Providers
• Dedicated Dark Fibre Offers
• Regional Providers
•What is the Correct Architecture?
•Is there a Common View of Control and Resource Allocation ?
•Can we Implement a Managed Environment Across Multiple Networks?
•Is Interface Definition Well Resourced and Understood?
The Technical Challenges
Service Activities
• SA1 : Procurement– Transmission capacity, PoP equip’t, maintenance & operations
• SA2 : Network Operations and Basic Services
– Initial basic set of services, developed as technical prog.
• SA3 End-to-End Quality of Service– Guaranteed for specific traffic & specialist projects
• SA4 Connecting Other World Regions
– Greater consolidation of global connectivity, co-operation initiatives for seamless work with world regions
Networking Activities
• NA1 Management of GN2• NA2 GN2 Dissemination Activities• NA3 Support for Users & User
Consultancy• NA4 NREN Development & Support• NA5 Foresight Study• NA6 Co-ordination of RTD Activities
