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. I've only tested the build on x86_64 OSX so you may need to tweak the build script for your system. If you do get the build working on other systems please submit a pull request. Once you build the C source you can build UDT by setting your GOPATH and PATH, then building github.com/murphybytes/udt.go/...
There is a test script 'test.sh' in the root directory of the project. Set your GOPATH, then your PATH to $GOPATH/bin then run the test script from the project root. The test script will start a UDT server that will listen for text strings from clients, the clients will send the string to the server, the server sends them back to client performing a comparison. The go test programs are in udt.go/test/client udt.go/test/server
