Consider a system with a window size of W that transmits b-bit frames at a rate of x bits/second over a link with a one-way propagation delay of t seconds.

a) Write a formula to determine the minimum window size so that transmission never stops under error free conditions. If b = 1,000, x = 10,000 bits/second, and     t = 275 milliseconds, what is minimum window size?

b) For the same system using a stop and wait protocol, what is the utilization?
