we know that a rough estimation of TCP rate is: WINDOW/RTT, where `WINDOW`

is the min(CWIN, RWIN), CWIN is the congestion window size of the sender, while RWIN is the receiving window.

nowadays, the encoding rate of videos may be 1000KB/s(8000kbit/s), if RTT is 500ms, it needs the window size to be 2000KB. But we know that usually the receiving window size is below 64KB, there is a big gap.

so if RTT is too large, TCP streaming is not possible?

Is my understanding right?

thanks!
