The EU Data. TAG project • Two main focus: – Grid applied network research – Interoperability between Grids • 2. 5 Gbps transatlantic lambda between CERN (Geneva) and Star. Light (Chicago) – dedicated to research (no production traffic) • Expected outcomes: – Better interoperability between GRID projects in Europe and North America • Data. Grid, possibly other EU funded Grid projects • PPDG, Gri. Phy. N, DTF, i. VDGL (USA) Tiziana Ferrari The Data. TAG Projct, Roma Nov 27 2001 2

The EU Data. TAG project (cont) • European partners: INFN (IT), PPARC (UK), University of Amsterdam (NL) and CERN, as project coordinator – Strong collaborations already in place with ANL, Caltech, FNAL, SLAC, University of Michigan, as well as Internet 2 and ESnet. • Budget: 3. 9 MEUR • 2 years • Expected starting date: December 1, 2001 • Kick-off meeting: CERN, Dec 5 2001 • NSF support through the existing collaborative agreement with CERN (Eurolink award) Tiziana Ferrari The Data.

Work Packages • WP 1: Provisioning & Operations (CERN) – Will be done in cooperation with DANTE – Two major issues: • Procurement • Routing, how can the Data. TAG partners have transparent access to the Data. TAG circuit across GEANT and their national network? • WP 5: Information dissemination and exploitation (CERN) • WP 6: Project management (CERN) Tiziana Ferrari The Data.

Work Packages (cont) • WP 2: High Performance Networking (PPARC) – High performance Transport • tcp/ip performance over large bandwidth*delay networks • Alternative transport solutions – End to end inter-domain Qo. S – Advance network resource reservation • WP 3: Bulk Data Transfer & Application performance monitoring (University of Amsterdam) – Performance validation – End to end user performance • Validation, Monitoring, Optimization – Application performance • Netlogger Tiziana Ferrari The Data. TAG Projct, Roma Nov 27 2001 7

Work Packages (cont) • WP 4: Interoperability between Grid Domains (INFN) – GRID resource discovery – Access policies, authorization & security • Identify major problems • Develop inter-Grid mechanisms able to interoperate with domain specific rules – Interworking between domain specific Grid services – Test Applications • Interoperability, performance & scalability issues Tiziana Ferrari The Data.

Work programme: details • The lambda availability is expected in the second half of 2002 • Initially, test systems will be either at CERN or connect via GEANT • GEANT is expected to provide VPNs (or equivalent) for Datagrid and/or access to the GEANT Po. Ps. • Later, it is hoped that GEANT will provide dedicated lambdas for Datagrid • Initially a 2. 5 Gb/sec POS link • WDM later, depending on equipment availability Tiziana Ferrari The Data.
