Two computers A and B open a TCP connection between themselves. Consider the flow of data from A to B. B’s RWND as known to A is 25 MSS. A’s initial CT = 12 MSS. At time unit 7, one of A’s RTO timer goes off, at time unit 14 A receives three duplicate ACKs, and at time unit 20 A gets one more timeout of its RTO timers.


Show in a graph the detailed changes of A’s congestion window (CWND) if TCP Reno is used.
