Right. Are any of those boxes Linux-based? Otherwise the BPF
implementation is not much use to you :)

No concrete plans yet, but the obvious thing that comes to mind is
looking for latency variation within flows, possibly correlating it with
rate. I tried to do something with the Measurement Labs NDT dataset some
years back:

For a middlebox monitor, the most interesting for identifying possible
interventions is to figure out which path the data corresponds to.
Depends a little on the network topology and the position of the
middlebox what would be a good way to do that...
