Abstract :
Scientific applications require sophisticated data management capabilities. We present the design and implementation of a data replication service (DRS), one of a planned set of higher-level data management services for Grids. The capabilities of the DRS are based on the publication capability of the lightweight data replicator (LDR) system developed for the LIGO Scientific Collaboration. We describe LIGO publication requirements and LDR functionality. We also describe the design and implementation of the DRS in the Globus Toolkit Version 4.0 environment and present performance results.
