We have a PhD student working on a BPF-based implementation of pping:
My hope is that this can end up being an always-on thing that runs on
the router and can be used to adjust the CAKE parameters as latency
There are still a few rough edges on the implementation (most notably
the data output can become quite high), but it should otherwise be
usable, so feel free to take it for a spin. Needs a fairly recent LLVM
(10+ IIRC) to compile the BPF parts.
