I wonder why this hasn't made the rounds here. From what I see, a change in this part (e.g. lower buffers in customer routers, or a change (yet another) to the congestion control algorithms) would do miracles for end-user perceived performance and should help in some way with the net neutrality dispute.
I'd say this is common knowledge and has been for a long time.
In the world of CPEs, lowest price and simplicity is what counts, so nobody cares about buffer depth and AQM, that's why you get ADSL CPEs with 200+ ms of upstream FIFO buffer (no AQM) in most devices.
you're going to see more of it, at a minimum cpe are going to have to be able to drain a gig-e into a port that may be only 100Mb/s. The QOS options available in a ~$100 cpe router are adequate for the basic purpose. d-link dir-825 or 665 are examples of such devices
Personally I have MQC configured on my interface which has assured bw for small packets and ssh packets, and I also run fair-queue to make tcp sessions get a fair share. I don't know any non-cisco devices that does this.
the consumer cpe that care seem to be mostly oriented along keeping gaming and voip from being interfereed with by p2p and file transfers.
