We present a data transfer system for the grid environment built on top of the open source FDT tool (Fast Data Transfer) developed by Caltech in collaboration with the National University of Science and Technology (Pakistan). The enhancement layer above FDT consists of a client program - fdtcp (FDT copy) and a fdtd service (FDT daemon). This pair of components allows for GSI authenticated data transfers and offers to the user (or data movement production service) interface analogous to grid middle-ware data transfer services - SRM (i.e. srmcp) or GridFTP (i.e. globus-url-copy). fdtcp/fdtd enables third-party, batched file transfers. An important aspect is monitoring by means of the MonALISA active monitoring light-weight library ApMon, providing real-time monitoring and arrival time estimates as well as powerful troubleshooting mechanism.
