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)
HD-00-223
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

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

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

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 (?)
HD-00-223
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
HD-00-223
Tests/Piloting
• Year 1 commitment• premium IP• MPLS/VPN• multicast improvement• IPv6• traffic measurement
• Annual update of “technology roadmap”
HD-00-223
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?
HD-00-223
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.
