It's as simple as using the same = mtu_time threshold for all tins. This does mean that low-rate tins (such as Bulk) will be controlled to = potentially unsustainably-low BDPs when competing against higher-rate = tins. However, that will only affect goodput in the low-rate tins (and = when ECN is not being used by the endpoints involved). I think that's = an unavoidable tradeoff, and controlling latency is more important in = this scenario. - Jonathan Morton
