Question

Host A and B are directly connected with a 100 Mbps 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 120 Mbps but Host B can read out of its TCP receive buffer at a maximum rate of 50 Mbps. Describe the effect of TCP flow control.

Answer 1

Host A and B directly connected to Mbps link.they receive buffer to fill up the fact that Host A will sending in Mbps data faster than B removing the data from it.Once buffer has filled.Host B send a message to Host A to stop sending data then Host B sending a TCP to Host A.Then buffer will fill up again and this process will repeat.
