On code points, Bruce can give better info, but one can grep src/*.c

That's kind of a complicated answer but I'll take a shot at it. There is a client side and a server side to any iperf3 measurement. The idea is that the server sits around and waits for clients to show up and request to run a test. The client first sets up a control connection to the server (this is always over TCP). They exchange a few messages to set up the parameters of the test, after which the test proper starts. Each test consists of some of send operations (number, size, and protocol determined by the client's command-line parameters). By default the client sends to the server, but it can be the other way around if the client is passed the -R/--reverse flag. After the end of the test there is another exchange of messages over the control connection, which basically allow the client to get results from the server. The implementation is somewhat complicated due to the many different types of tests that can be run and combinations of test parameters that interact in various ways. Feel free to ask if you have any more specific questions. Bruce. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming!
