(a) The distance from earth to a distant planet is approximately 9 × 1010 m. What is the
channel utilization if a stop-and-wait protocol is used for frame transmission on a 64
Mbps point-to-point link? Assume that the frame size is 32 KB and the speed of light
is 3 × 108 m/s.
(b 28)In the previous problem, suppose a sliding window protocol is used instead. For what
send window size will the link utilization be 100%? You may ignore the protocol
processing times at the sender and the receiver.
