UDP-based Data Transfer Protocol (UDT), is a high-performance data transfer protocol designed for transferring large volumetric datasets over high-speed wide area networks. Such settings are typically disadvantageous for the more common TCP protocol. The original C++ UDT project can be found on SourceForge http://udt.sourceforge.net/
First You'll need to compile the UDT C source code. To do this run the build script that is located in the root directory of the project. You'll need g++ on your system to successfully compile the UDT C library.
