Sorry, this just jostled in my brain now that I may be able to implement member fairness today, based on what you wrote earlier in a thread that I entirely missed: https://lists.bufferbloat.net/pipermail/cake/2018-May/003811.html <https://lists.bufferbloat.net/pipermail/cake/2018-May/003811.html>

George posted an example of assigning packets to a tin: https://lists.bufferbloat.net/pipermail/cake/2018-May/003809.html <https://lists.bufferbloat.net/pipermail/cake/2018-May/003809.html>

How does one send packets to a specific flow / queue?

This wouldn’t give both per-member and per-flow fairness, but at least per-member fairness might be possible. There are 1024(?) queues available and 800 members, so I’m just speculating that I could map members to a number from 0 to 800 (active member IDs packed and zero-based would work) and assign each member to their own flow. Thanks... :)
