The next generation of High Energy Physics experiments, ATLAS and CMS, proposed at the CERN Large Hadron Collider (LHC), will place heavy demands on the data acquisition and on-line filtering systems. Asynchronous Transfer Mode (ATM) is a candidate technology to implement the high performance network in the data collection system for the ATLAS experiment. This work presents the results of modeling and simulation studies which aim at integrating the detailed organization of the detector read-out, the trigger requirements and the capabilities of ATM switching networks. The status of hardware development of small scale demonstrators is outlined.
