Dave,

I didn't want to jump on this but I agree with your point.

QoS in providers today is used to prioritize packets for people paying a lot more than others for such things as VPN services.  The rest get usually extremely good "best effort" service as has been the case for most providers who have survived over the last decade or two (survived in some form or another, generous buyouts in the mid to late 1990s not withstanding).

There can be improvement.  Good to hear that there is interest again.  The bufferbloat discussion and work and the mention of transport area activity is a symptom of interest and activity regarding doing things better in the host, CPE, and access/edge devices.

Curtis
