  1. DataTAG Project The DataTAG Projct, Roma Nov 27 2001

  2. The EU DataTAG project • Two main focus: • Grid applied network research • Interoperability between Grids • 2.5 Gbps transatlantic lambda between CERN (Geneva) and StarLight (Chicago) • dedicated to research (no production traffic) • Expected outcomes: • Better interoperability between GRID projects in Europe and North America • DataGrid, possibly other EU funded Grid projects • PPDG, GriPhyN, DTF, iVDGL (USA) The DataTAG Projct, Roma Nov 27 2001

  3. The EU DataTAG 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 Internet2 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) The DataTAG Projct, Roma Nov 27 2001

  6. Work Packages • WP1: Provisioning & Operations (CERN) • Will be done in cooperation with DANTE • Two major issues: • Procurement • Routing, how can the DataTAG partners have transparent access to the DataTAG circuit across GEANT and their national network? • WP5: Information dissemination and exploitation (CERN) • WP6: Project management (CERN) The DataTAG Projct, Roma Nov 27 2001

  7. Work Packages (cont) • WP2: High Performance Networking (PPARC) • High performance Transport • tcp/ip performance over large bandwidth*delay networks • Alternative transport solutions • End to end inter-domain QoS • Advance network resource reservation • WP3: Bulk Data Transfer & Application performance monitoring (University of Amsterdam) • Performance validation • End to end user performance • Validation, Monitoring, Optimization • Application performance • Netlogger The DataTAG Projct, Roma Nov 27 2001

  8. Work Packages (cont) • WP4: 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 The DataTAG Projct, Roma Nov 27 2001

  9. 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 PoPs. • 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 The DataTAG Projct, Roma Nov 27 2001

  10. INFN: Participation - draft • CNAF, Padova, Milano, Torino (?) • 8 or 9 contracts available • Wp1, Wp2, Wp4 • Wp2: 2 fte, CNAF (S.Andreozzi, S.Cammarata) • Wp4: • 4.1: resource discovery: A.Cavalli, Cischini, + 1 fte • 4.2: security/authorization: R.Cecchini, Spataro, INFN security group • 4.3: internetworking of collective services: • Wp1 DataGrid • 1 fte CNAF • Milano and Padova (2 fte + 2 fte) The DataTAG Projct, Roma Nov 27 2001
