ABSTRACT
The developments in the Grid Computing Technologies make it feasible to use multiple clusters together to solve a single problem. The clusters of clusters can be viewed as a computational grid and a data grid infrastructure. Parallel File Transfer Protocol (PFTP) introduces the concept of data transfer using multiple parallel data paths between clusters. The protocol uses the striping format of the Parallel File System to push multiple stripes of the file over multiple TCP connections. In this paper we describe the effective design architecture and implementation of PFTP which uses the striping format of Parallel File System. The flexible, secure, fault tolerant and high performance design of PFTP can be useful for large Data Grids. Several experiments explain how it improves the data transfer rate. We also provide performance results of PFTP for a varying file data size of 100 MB to 4GB. The flexible, secure, fault tolerant and high performance design of PFTP can be useful for large Data Grids.
