Ah, dug out some emails which set me on the right path. Seems to be this

evidently, forgot all about:

Seems to work well enough, so go ahead and try it, I guess? :)
Installed the latest flent and traffic-gen from source yesterday after
our mail conversations.
Ran into an issue with the bursts test, where the flent test continues
to run. Resulting in the node generating traffic for the full pipe for
hours on end. My observation is the test does not terminate for unknown
reasons.
Found this test running from yesterday afternoon this morning still
actively running. Which was strange. As the test duration was set to
begin => 30s => 300s => 30s => end.

Could this happen if the node is not able to connect to the remote end
during the test? I.e. the inband control channel is not possible (to
little bandwidth available), due to the bandwidth just filling up the
wired pipe... :think:
