FLExible Network Tester for bufferbloat testing and more


The FLExible Network Tester is a Python wrapper to run multiple simultaneous
netperf/iperf/ping instances and aggregate the results.

Tests are specified as config files (which are really Python), and
various parsers for tool output are supplied. At the moment, parsers for
netperf in -D mode, iperf in csv mode and ping/ping6 in -D mode are
supplied, as well as a generic parser for commands that just outputs a
single number.

Several commands can be run in parallel and, provided they output
timestamped values, (which netperf ping and iperf do, the latter with a
small patch, available in the misc/ directory), the test data points can
be aligned with each other in time, interpolating differences between
the actual measurement points. This makes it possible to graph (e.g.)
ping times before, during and after a link is loaded.

Version: 2.1.1
