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 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)

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)

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

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

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
