Abstract. Data grids are middleware systems that offer se-

area networks. Main challenge in their design is to provide
reliable storage, search and transfer of numerous or large
files over geographicallydispersed heterogeneous platforms.
The Storage Resource Broker (SRB) is an example of such a
system that has been deployed in multiple high-performance
scientific projects during the past few years. In the present
