Suppose there is a 10 Mbps microwave link between a geostationary satellite and its base station on Earth. Every minute the satellite takes a digital photo and sends it to the base station. Assume a propagation speed of $2.4 \times 10^8$meters/sec.

1. What is the propagation delay of the link?
1. What is the bandwidth-delay product, $R \times d _{prop}$?
2. Let x denote the size of the photo. What is the minimum value of x for the microwave link to be continuously transmitting?

Suppose two hosts, A and B, are separated by 20,000 kilometers and are connected by a direct link of R = 2 Mbps. Suppose the propagation speed over the link is $2.5 10^8$meters/sec. How long does it take to send the file, assuming it is sent continuously? Suppose ... send a packet until the preceding one is acknowledged. How long does it take to send the file? Compare the results from (a) and (b).

This elementary problem begins to explore propagation delay and transmission delay, two central concepts in data networking. Consider two hosts, A and B, connected by a single link of rate R bps. Suppose that the two hosts are separated by m meters, and suppose the propagation speed along the link is ... $d _{prop}$ equals $d _{trans}$.

Suppose two hosts, A and B, are separated by 20,000 kilometers and are connected by a direct link of R = 2 Mbps. Suppose the propagation speed over the link is 2.5×1082.5×108 meters/sec. suppose we can modify R. For what value of R is the width of a bit as long as the length of the link?
