Host A and B are directly connected with a 100Mbps link. There is one TCP connection between the two hosts, and Host A is sending to Host B an enormous file over this connection. Host A can send its application data into its TCP socket at a rate as high as 140 Mbps but Host B can readout of its TCP receive buffer at a maximum rate of 70 Mbps. Describe the effect of TCP flow control.
