But that's exactly the problem. Single queue AQM does not isolate L4S traffic from "classic" traffic, so the latter suffers from the former's relative aggression in the face of AQM activity. This isolation is the very reason why something like DualQ is proposed, so the fact that it can be defeated into this degraded single-queue mode is a genuine problem. May I direct you to our LFQ draft, published yesterday, for what we consider to be a much more robust approach, yet with similar hardware requirements to DualQ? I'd be interested in hearing feedback. - Jonathan Morton
