Consider a system with a window size of W. A transmitter transmits b-bit frames at a rate of x bit/second over a link with a one-way propagation delay of t seconds. When the receiver receives the b-bit frame, it responds with an a-bit acknowledgment that also experiences a one-way propagation delay of t seconds.
Â
(a) Write a formula for utilization in terms of W, b, x, a, and t.
Â
(b) If W = 3, b = 1,500, a = 60, x = 9600 bits/second, and t = 300 milliseconds, what is the utilization (as a percentage).
