  1. Networks in Europe and the World GÉANT Howard Davies DANTE NORDUnet 2000 Conference

  2. The Journey Ahead • Starting Point • Direction • Vehicle • Destination

  3. TEN-155 Service • Basic IP service • 19 NRENs (inc. NORDUnet) • access capacities in range • 10 Mbit/s (IE, LU) • 622 Mbit/s (DE, NL) • MBS (Managed Bandwidth Service) • ATM-based • guaranteed capacity • typically used for demonstrations • VPN capability • testing of new technology (native multicast, diffserv, MPLS, IPv6)

  4. The Direction • Expanded geographic coverage • All FP5 countries • Connectivity to other world regions • Much higher capacities • Target: 2.5 Gbit/s in 8 locations in 2001 • Tens (or hundreds) of Gbit/s within 4 years • Improved resilience • End-to-end QoS

  5. Capacity Requirements • US demonstrations • Research Channel HDTV: 5 streams of 200 Mbit/s • Internet2 Land Speed Record: 830 Mbit/s • Internet2 LSR, 2nd edition: 30 Oct 00 • Development of Grid technologies and services • distributed, high speed computation with large data sets • application areas include: nuclear physics, earth observation, meteorology, multi-disciplinary design, computational chemistry, drug discovery, finance engineering, business decisions, multimedia

  6. QoS: the “Infinite Bandwidth” Debate • Over-provision of bandwidth • is simple • goes a long way towards meeting QoS needs • is adequate in the short term, but • From the Abilene QoS Planning Group: • congestion on part of end-to-end path • prepare for congestion (“risks . . victim of . . success”) • “blaze a trail . . . exemplary QoS architecture” • Distributed computing services, including grids, need predictable QoS

  7. The Vehicle • Géant - the network service to succeed TEN-155 • GN1 - EC project under FP5/IST • Four year contract with 25 NRENs plus DANTE • effective 1 Nov 00 • 80 Meuro committed by EC • further funding available (?), eg for US • contract signature Oct 00 (?)

  8. Géant Services • Basic IP service • including connection to research networks in other regions • Native multicast • Premium IP service • Guaranteed capacity ) end-to-end, with • Virtual private networks) NREN involvement • New services • IPv6 • support (not ATM) for “disruptive” testing

  9. Tests/Piloting • Year 1 commitment • premium IP • MPLS/VPN • multicast improvement • IPv6 • traffic measurement • Annual update of “technology roadmap”

  10. Géant Technology • “Vision” • ideal is dedicated fibre + DWDM, but • is it available (throughout Europe)? • is it ready (for operational service)? • is it affordable? (equipment costs?) • Tender • ITT issued 7 Jul 00 to 88 organisations (inc. 12 NRENs) • “open” specification (min 2.5G, target 8 locations) • Timetable • deadline for tenders is 29 Sep 00 • TEN-155 contracts continue till 30 Nov 01 • 1/2/3/4 year commitment?

  11. The Destination • The most advanced possible networking support for the research and education community throughout Europe • A high quality network service to which other world regions wish to connect.
