Host A and B are directly connected with a 200 Mb/s 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 application data into the link at 100 Mb/s, but Host B can read out of its TCP receive buffer at a maximum rate of 50 Mb/s. What is the long term rate at which host A will communicate with host B?
