Consider an instance of TCP’s Additive Increase Multiplicative Decrease (AIMD) algorithm where the window size at the start of the slow start phase is 2 MSS and the threshold at the start of the first transmission is 8 MSS. Assume that a timeout occurs during the fifth transmission. Find the congestion window size at the end of the tenth transmission.
(A) 8 MSS
(B) 14 MSS
(C) 7 MSS
(D) 12 MSS
After Timeout We should start from 1 MSS irrespectice of What size is at the start or After Timeout again we have to take from 2 MSS?? AND
The question asks After the end of 10th Transmission so My approach is
At t=1, =>2mss t=2, =>4mss t=3, =>8mss t=4, =>9mss (after threshold additive increase) t=5, =>10mss (fails) t=6, =>2mss t=7 =>4mss t=8, =>5mss t=9, =>6mss t=10, =>7mss.So at the end of 10th transmission 7 segments will be transmitted.
So the Answer Should be 8MSS or 7MSS???
