Yes, they are. But in general AQM can’t be used to solve that problem without also suffering poor throughput; combining AQM with FQ *does* solve it. Just like FQ is unfair to single flows competing against a swarm, but classifying the swarm traffic into a separate traffic class fixes that problem too. Which of course is why cake uses AQM, FQ *and* Diffserv, all at once. The linked paper didn’t measure HLC against fq_codel, even though they mention fq_codel. That’s a major shortcoming. - Jonathan Morton _______________________________________________ Codel mailing list [email protected] https://lists.bufferbloat.net/listinfo/codel
