Ideally, always on monitoring and export at the PE. An in= cremental first step in an adhoc off box tester, maybe deployed with the pe= rfsonar suite.

Meaningfully vi= sualizing the output seems challenging. Do you have any insights on that pa= rt?

Right, I meant more in terms of deployment: are you looking to run this
as an always-on monitor on a middlebox, or are you just running ad-hoc
measurements on a client device?

I ask because we have a PhD student working on a re-implementation of
pping in BPF, the goal of which is precisely to be able to run as an
always-on monitor:
https://github.com/xdp-proje= ct/bpf-examples/tree/master/pping

So any insights into what you're thinking of doing with the tool would<= br> potentially be helpful - adding in Simon, who's writing the code.
