TCP uses a window: the maximum number of packects that you can receive
before you send an ACK. As long as ACK come flowing, the window size

Limit the ACK, you limit/reduce the size of the window, so you
limit/reduce the incoming trafic.

I beleive there could even be some nasty rewritting that would
artifically change the window size so the TCP stream is slowed down.
