Hallo,

since this ML has a strong qdisc oriented spin, I'd like to share what I did end of last year. I was playing a little with BCC/eBPF and kernel flow interfacing [1] ... excuses for the code quality, it was prototyping, though ...

I can imagine reviving efforts as to fleutan, since I perceive many usefel aspects as to flowing and associations of it are simply not covered yet, at least no conveniently accessible from user land end and not on from a per node angle. Especially the case for backend scenarios with > thousands of flows. Quite some acre to be plowed if you asked me. Feel free to prove me wrong. Mostly, I perceive quicker leaps are down to mundane things like efficient, convenient diggestabilty of low level kernel interfacing output ... e.g. iproute2. A lot of vibrant dymanics are perceivable lately in this corner though - I'm applauding. [2][]

Until further progress, might to the merrit of some.

$ sudo ./fleutan flows -q -i 5
