The xDotGrid Native, Cross-Platform, High-Performance xDFS File Transfer Framework

摘要

In this paper we introduce and describe the highly concurrent xDFS filetransfer protocol and examine its cross-platform and cross-languageimplementation in native code for both Linux and Windows in 32 or 64-bitmulti-core processor architectures. The implemented xDFS protocol based onxDotGrid.NET framework is fully compared with the Globus GridFTP protocol. Wefinally propose the xDFS protocol as a new paradigm of distributed systems forInternet services, and data-intensive Grid and Cloud applications. Also, weincrementally consider different developmental methods of the optimum filetransfer systems, and their advantages and disadvantages. The vision of thispaper tries as possible to minimize the overhead concerned with the filetransfer protocol itself and to examine optimal software design patterns ofthat protocol. In all disk-to-disk tests for transferring a 2GB file with orwithout parallelism, the xDFS throughput at minimum 30% and at most 53% wassuperior to the GridFTP.
