They can QoS the downstream fine it seems maybe because its before it hits sending it down Docsis but for upstream each channel has a given amount of bandwidth so why can't each upstream handle the scheduling for modems send data as a QoS its like the upstream has no QoS at all and people sending data get all the upstream bandwidth and me sending a ping reply is buffered in the modem waiting to be sent. I have to say it 2021 and the problem was well known years ago so why no improvement other then to add more upstream channels which will not help given to days upload speeds.
I also wonder if they can QoS the upstream after Docsis depending on how the channels are load balanced and without a DoS being sent by some one...thinking of this make me wonder why we don't see UDP capacity tests an more....so one upstream @ QAM64 is 30Mb? And if 4 upstream channels are load balanced evenly then that 120Mb to QoS or maybe less then that after Docsis to QoS by a router. But if the channels are not load balanced evenly or there are 5 channels then its going to cause problems.
