Assume that when establishing a TCP connection, the threshold for the Congestion Window (cwnd) is 16 segments. The congestion control algorithm is TCP Reno. In the 5th round, a time out occurs.The ACK packets are then received correctly until the 13th round. In this round, a triple duplicate ack occurs. Then until the 16th round, the ack packets are received correctly. Show these steps by plotting (the vertical axis is the congestion window capacity (cwnd) and the horizontal axis is the round number). Also specify the threshold value change each time it occurs.
