5 M. Campanella - TNC Antalya - May Reasons More capacity (factor of 20), new services (QoS, IPv6,…), simplification, exploit fibers Key elements - GPoPs in users’ or neutral premise - GPoP central to MANs and Regional networks, high speed interconnects - unitary model - State cofinancing at 50% - Ready for access to all student population - Full support to european test activities - Ready for mediterranean access - data link agnostic (use of, SDH, ATM, GbE )

6 M. Campanella - TNC Antalya - May Items to follow closely Although DWDM Gb speed in the backbone is a reality, speed in the last mile might be slower: - north better served than south - larger cities cabled, not countries LANs are slow to evolve and only a small percentage is ready for QoS Users’ site frequent misconfigurations DWDM provider infrastructure is new need to deal with multiple service providers and dark fibers
