The distance from the moon to the Earth is approximately 360,000 km, and data travels over the link at the speed of light -3 10^8 m/s. a. Calculate the propagation delay. d_prop= b. Calculate the transmission delay to send 10MB of data. d_trans= c. Calculate the total delay (earth to the moon and back) to send 10MB of data to the moon. Assume that there is no processing or queueing delay and that the ACK back from the moon is of negligible size. d_total = d. What is the maximum number of bits that will be in the link at any given time? e. Consider sending 120Mb file from Earth to the Moon. Suppose the file is sent continuously as one big message. What is the maximum number of bits that will be in the link at any given time?
