Network Engineering and Management question:

8. Suppose two hosts: A and B, are separated by 10,000 kilometers and are connected by a direct link of R = 1 Mbps. Suppose the propagation speed over the link is 2.5*100000000 meters/sec.

e. Derive a general expression for the width of a bit in term of the propagation speed s, the bandwidth R, and the length of the link m.

f. Suppose we can modify R. for what value of R is the width of a bit as long as the length of the link?
