Q$.$ No $1$:

a$)$Consider the effect of using slow start on a line with a $10$ msec RTT and no congestion. The receiver window is $24$ KB and the maximum segment size is $2$ KB$.$ How long does it take before the first full window can be sent?

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

$8$ MSS

$14$ MSS

$7$ MSS

$12$ MSS
