  1. GÉANT: deployment and development of Networking for European Research Roberto Sabatino - DANTE

  2. GÉANTEuropean Gbps Network for Research • 10 Gbps in 8 locations, 9 circuits • 2.5 Gbps in 7 locations, 12 circuits • 3 providers: Colt, DeTe, Telia • Connects 31 NRENs • Connectivity to N.A (3x2.5Gbps)

  3. Topology LV EE LT SE UK PL IE 10Gbps NL BE LU 2.5 Gbps FR DE CZ ES SK 34 - 622 Mbps IL PT CH IT HU AT RO BG GR SI HR CY

  4. Providers LV EE LT SE UK PL IE COLT IL NL BE LU DeTe FR DE CZ ES Telia SK PT CH IT HU AT RO BG GR SI HR CY

  5. European Coverage forwavelengths • Easy in UK, FR, NL, DE, BE • Accessible in AT, CH, ES, IT, CZ, HU, SK, PL, SE • Too difficult in GR, PT, SI • Virtually impossible elsewhere • Europe is still not uniform! Especially in the access

  6. Technology • Nortel, Lucent DWDM equipment • 10 Gbps wavelengths are presented as SDH (i.e POS interface on routers) • 2,5Gbps are a mix of wavelengths and “transparent” SDH services (provide clocking), presented as SDH

  7. GÉANT Development • Multicast, ipv6, monitoring • Support for User groups • Premium IP (MOICANE, LONG, AQUILA…) • MPLS techniques for support of testbeds (6NET, ATRIUM, DATATAG) • How can “pure optical networking” help? • beyond 10Gbps to hundreds of Gbps • 40Gbps ? • Multiple wavelengths ?

  8. Beyond 10Gbps • 40Gbps in pipeline on DWDM equipment • Router equipment readiness unclear • Business case for carriers unclear • Not only 40Gbps, but higher utilisation of spectrum on fibres • more wavelengths (up to 160) • at various capacities (2.5, 10, 40 Gbps) • Goal is to have access to 100+Gbps by 2004

  9. What next ? • Manage backbone resources • how do we handle more wavelengths, optimise routing • Manage user requests • circuit switched vs. packet switched • granularity - how do we handle XMbps out of 10Gbps? • how to cope with reduced EU coverage for user requests (grids)? • What are the network components that will help us do this?

  10. Thank You !
