GridFTP

GridFTP is a high-performance, secure, reliable data transfer protocol optimized for high-bandwidth wide-area networks. It is based upon the Internet FTP protocol, and it implements extensions for high-performance operation that were either already specified in the FTP specification but not commonly implemented or that were proposed as extensions by our team. The current GridFTP protocol specification is now a "proposed recommendation" document in the Global Grid Forum (GFD-R-P.020).

GridFTP uses basic Grid security on both control (command) and data channels. Other features include multiple data channels for parallel transfers, partial file transfers, third-party (direct server-to-server) transfers, reusable data channels, and command pipelining.
