Rate limiting the CPE doesn't seem to really impact the buffer queue depth on the 100G upstream switch feeding the 1G customer port. In addition, sticking them on something like 90% customer speed plan or 90% port speed also doesn't help, and in fact with many customers, they are now pissed because they never hit their plan speeds in a speed test.

Something I have always done I actually provision to account for packet overhead, so you might speed 2-3% higher speeds than your plan limit in a speed test, but psychologically the customer is getting more than they paid for, and most seem to be very happy about that.

But, rate limits were already in place long before anything about queue depth was even discussed, so that was nothing new. CAKE OTOH has had a very noticable impact on the customer experience, when their kids XBox can download that 250G update without impacting the voip call or wifi offloading another member of the household is on. Alternatively, that same gamer can play while Mom is downloading something near max throughput without having latency spikes and packet loss.

Yes, you're on to something about the customer experience in general that I'm tracking down myself. Orb is also trying to get a look, but I'm not a fan so far of that tool/platform https://orb.net/
