Assignment 2 Results Sheet
Question 1 – Number of retransmissions and throughput with different retransmission timeout values with stop-and-wait protocol. For each value of retransmission timeout, run the experiments for 5 times and write down average number of retransmissions and average throughput.
Question 2 – Discuss the impact of retransmission timeout value on the number of retransmissions and throughput. Indicate the optimal timeout value from a communication efficiency viewpoint (i.e., the timeout that minimizes the number of retransmissions while ensuring a high throughput).
Question 3 – Experimentation with Go-Back-N. For each value of window size, run the experiments for 5 times and write down average throughput.
Question 4 – Discuss your results from Question 3.
Question 5 – Experimentation with Selective Repeat. For each value of window size, run the experiments for 5 times and write down average throughput.
Question 6 - Compare the throughput obtained when using “Selective Repeat” with the corresponding results you got from the “Go Back N” experiment and explain the reasons behind any differences.
Question 7 – Experimentation with iperf. For each value of window size, run the experiments for 5 times and write down average throughput.
Question 8 - Compare the throughput obtained when using “Selective Repeat” and “Go Back N” with the corresponding results you got from the iperf experiment and explain the reasons behind any differences.
