a. Consider an instance of TCP's Additive Increase Multiplicative Decrease (AIMD) 5 algorithm
where the window size at the start of the slow start phase is 2 MSS (maximum segment size) and
the threshold at the start of the first transmission is 8 MSS. Assume that a time-out occurs during
the fifth transmission. Find the congestion window size at the end ofthe tenth transmission.
