COMPUTER NETWORKS QUESTION : If two hosts start communicating using TCP Reno (with fast retransmit and fast recovery). Answer the following: a) What would be the size of the congestion window and the congestion threshold after the 9th RTT if the congestion threshold was initially = 4 MSS and no duplicate Acknowledgement or timeout have been observed during the first 9 RTT. b) If at the 10th RTT, the sender observed duplicate Acknowledgment, what would be the size of the congestion window and the congestion threshold in the next RTT? (the 11th RTT). What congestion control phase would the sender enter next? c) From the 11th RTT to the 18th all the segments that were sent had been acknowledged correctly. But at the 19th RTT, the sender observed a timeout before it received any acknowledgement. What would be the size of the congestion window and the congestion threshold in the next RTT? (the 20th RTT). What congestion control phase would the sender enter next?
