said by rradina:Depending on the TCP receive window, one could chew through quite a bit of upstream bandwidth to sustain 305Mbps down. I'd guess north of 5Mbps would be consumed by ACKs unless a large receive window is used. Depending on quality, too large a window would kill performance if there are too many retransmits.
It would seem only fair if they provided at least 20Mbps up for 305Mbps down to keep the receive window reasonable and not require ultra low latency to the source server.
Comcast already provides 20 Mbps on its upstream for their 105 Mbps downstream tier. I suspect they woud provide more for a 305 Mbps tier.
