A high speed file transfer protocol using UDP and TCP for high speed long distance networks, much faster than new TCP congestion control algorithms. Based on Indiana University 2002 Tsunami source code. Contains real-time VSIB DAQ extensions.

Currently Client can only connect to Server and Download the files, is there a way client can upload a file to server?(other way around).

[Jan Wagner]

Unfortunately no, no upload capability, by design.

For bidirectional and slightly more "modern" software you could look at rsync accelerated by UDT.

Either the original https://github.com/LabAdvComp/UDR

Or my forked version that adds a command line option "[-r max-bw] Maximum bandwidth to utilize (Mbps)" in case bandwidth capping is required: https://github.com/jwagnerhki/UDR

This does not need any continuously running server at the other end, just SSH login and the 'udr' binary installed at the other end (or rather, both ends) is sufficient.

The advantage over Tsunami is bidirectional transfer, and all the capabilities and options of 'rsync' (e.g., wildcards, resumeability).

thanks a lot for response.. if I try UDT ,will there be any change in file transfer speed? for me very large file transfer speed is more important at the moment. your thougts/inputs?
