A TCP connection uses the Reno version. MSS is 1 KB. The initial ssthresh is set at 20 KB. rwnd is 24 KB throughout. Totally there are 20 rounds of transmission. The 12^th round results in a triple duplicate ACK. The 15^th round results in a time-out. All other rounds result in successful transmissions.

(i)Fill up the table provided with the following information for each round:

Round ssthresh in KB cwnd in KB

1 20 1

.

(ii)What is total amount of data successfully transmitted between rounds 10-15 (both inclusive)?

(iii)What is the link utilization between rounds 1-5 (both inclusive)? Assume RTT= 24 ms and bit rate of 10 Mbps. To simplify calculations you can also assume 1 KB = 1000 Bytes.

(iv)Assuming there is no rwnd limitation and no loss events, what is the maximum possible value of cwnd?
