The benefit for = endsystems comes from the "fq" (flow queuing) part, not from the "codel" = part of fq_codel? That's a fair characterisation, yes. In fact, even for middleboxes, the "flow isolation" semantics of FQ have = the most impact on reducing inter-flow induced latency. The "codel" = part (AQM) helps with intra-flow latency, which is usually much less = important once flow isolation is in place, but is still worth having. - Jonathan Morton
