Flent considers itself the client, so 'upload' is TCP_STREAM. As more use cases have emerged, this has turned out to not always be the case, of course; WiFi test scenarios such as you are doing being the most prominent example. There's a --swap-up-down parameter which will switch all instances of TCP_STREAM to TCP_MAERTS and vice-versa, though. > Second question: Is there any documentation that can help me figure out > exactly what traffic is running in each test type? > I've tried looking at the .conf and .inc files, in flent/tests but can't > figure it out. Not really :/ There's https://flent.org/tests.html, but it hasn't really kept up with new tests being added. However, you can see it after the fact: The exact command lines for each data series is stored (along with a bunch of other data) in the SERIES_META object in the data file. Use the GUI to browse this, or print it with 'flent -f metadata datafile.flent.gz'. -Toke _______________________________________________ Flent-users mailing list Flent-users@flent.org http://flent.org/mailman/listinfo/flent-users_flent.org
