possible. For this assignment, assume 1K = 1000 bytes, 1M = 1,000,000 bytes, 1G = 1,000,000,000 bytes, 1Byte = 8 bits and 1second = 1,000 ms = 1,000,000μs/n2. Suppose a 300-Mbps

point-to-point link is being set up between Earth and a new lunar colony. The distance from the moon to Earth is approximately 385,000 km, and data travels over the link at the speed of light 3.0 * 10³ m/s. (a) Calculate the minimum RTT for the link (6 points) (b) Using the RTT as the delay, calculate the delay x bandwidth product for the link. (6 points) (c) A camera on the lunar base takes pictures of Earth and saves them in digital format to disk. Suppose Mission Control on Earth wishes to download the most current image, which is 25MB. What is the minimum amount of time Page 215 that will elapse between when the request for the data goes out and the transfer is finished? (8 points)
