The project is used to test the tcp transfer speed between client side with server side.

First, you should launch the BandWidthServer.exe at server side to listern client's connection. and then run the BandWidthClient.exe with desired options.

you can upload[/downlod] fixed amount of data to[/from] server and then calculate the time waste, or provide certain amount of time and see how many data the client upload[/downlod] to[/from] server.

Finally, figurate out and show the speed statistics.
