• Reminder of Remit• Procurement history (why so long?)• Planned GÉANT2 build• Equipment to do it
Agenda
TF-NGN-18, 28-29th July 2005, Paris – Michael Enrico ([email protected])
• Upgrade GÉANT (1)– Reached end of 4-year funding cycle– Possibility for greater infrastructure ownership (fibre)
• But requires longer term views than hitherto adopted
• Provide support for new services– Not just a bigger IP network…– …support for high-capacity P2P services…– …and (if needed)…lots of them!
• Facilitate (joint) R&D efforts• Extend geographical coverage
GÉANT2 (GN2 I3) Remit
