Problem 1: Consider the following figure. Assuming TCP Reno is the protocol experiencing the behavior shown above, answer the following questions. In all cases, you should provide a short discussion justifying your answer Note: this problem is counted for 10 points 45 40 35 2 30 n 25 2 20 c 15 b 10 0 2 468 10 12 14 16 18 20 22 24 26 Transmission round
g. What is the value of ssthresh at the 24th transmission round? h. During what transmission round is the 70th segment sent? i. Assuming a packet loss is detected after the 26th round by the receipt of a triple duplicate ACK, what will be the values of the congestion window size and of ssthresh? Suppose TCP Tahoe is used (instead of TCP Reno), and assume that triple duplicate ACKs are received at the 16th round. What are the ssthresh and the congestion window size at the 19th round? k. Again suppose TCP Tahoe is used, and there is a timeout event at 22nd round. How many packets have been sent out from 17th round till 22nd round, inclusive?

Answer #1

The answers for the given questions is written below:

g) The value of ssthresh at the 24th transmission round 13.

h) The transmission round is the 70th segment sent is 7.

i) If a packet loss is detected after the 26th round by the receipt of a triple duplicate ACK, then the value is 4.

j) Suppose TCP Tahoe is used (instead of TCP Reno), and assume that triple duplicate ACKs are received at the 16th round. Then the ssthresh and the congestion window size at the 19th round is 1 and transmission round is 21.

k) Again suppose TCP Tahoe is used, and there is a timeout event at 22nd round, then the packets have been sent out from 17th round till 22nd round(inclusive) is 52.

What is the advertised window size the receiver sent to the sender? Suppose packet 12 is the last packet sent by the sender. What’s the effective window size at the sender? Can the sender send out packet 13 at this moment? How about packet...
