A receiving host has failed to receive all of the segments that it should acknowledge. What can the host do to improve the reliability of this communication session?
A
Send a different source port number
B
Restart the virtual circuit
C
Decrease the sequence number
D
Decrease the window size
Correct Answer: Decrease the window size
A receiving host can control the transmitter by using flow control ( TCP uses windowing by default). By decreasing the window size, the receiving host can slow down the transmitting host so the receiving host does not overflow its buffers.
