Reliable file transfer in Grid environments

Abstract

Grid-based computing environments are becoming increasingly popular for scientific computing. One of the key issues for scientific computing is the efficient transfer of large amounts of data across the Grid. In this paper we present a reliable file transfer (RFT) service that significantly improves the efficiency of large-scale file transfer. RFT can detect a variety of failures and restart the file transfer from the point of failure. It also has capabilities for improving transfer performance through TCP tuning.
