High-speed networks and services for data-intensive Grids: The DataTAG Project

The High-Energy and Nuclear Physics (HENP) community is preparing to take up a major challenge while the Large Hadron Collider (LHC) is under construction at the European Organization for Nuclear Research (CERN). The main goal of this new particle collider is to discover the Higgs boson, an elementary particle that would explain how particles acquire mass [1,2]. Based on current estimates, 12–14 PB (a PetaByte is 1015 Bytes) of data will be generated by the LHC every year [3]. This data will come from four LHC experiments: ALICE [4], ATLAS [5], CMS [6] and LHCb [7]. No HENP organization in the world has enough proc t L [ a s r e a w p a
