Well, the CE response at their end is definitely not Multiplicative Decrease. I haven't dug into it more deeply than that. But they're also not running AccECN, nor are they "proactively" sending CWR to get a "more accurate" CE feedback. I suspect they're running BBRv1 in this one. - Jonathan Morton _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
