The objective of this exercise is to realize how high distance and high bandwidth affect the performance of stop and wait. The distance from Earth to a distant planet is approximately 9 x 10° km. Assume that the frame size is 8 Kbits and the speed of light is 3 108 m/s. Assume that the bit rate is 10 Mbps. a) What is the efficiency (channel utilization) if a stop-and-wait protocol is used?
b) Suppose we use a window protocol. What should be the window size in frames to achieve the maximal efficiency (channel utilization)?
c) Plot the efficiency versus the distance when the bit rate is set to 10 Mbps. Discuss this plot.
d) Plot the efficiency versus the bit rate when distance is set to 9 x 109 km. Discuss this plot.
