Problem P25

Suppose two hosts, A and B, are separated by 20,000 kilometers and areconnected by a direct link of R = 2 Mbps. Suppose the propagation speedover the link is 2.5 108 meters/sec.a. Calculate the bandwidth-delay product, R dprop.b. Consider sending a file of 800,000 bits from Host A to Host B. Supposethe file is sent continuously as one large message. What is the maximumnumber of bits that will be in the link at any given time?c. Provide an interpretation of the bandwidth-delay product.d. What is the width (in meters) of a bit in the link? Is it longer than a footballfield?e. Derive a general expression for the width of a bit in terms of the propagationspeed s, the transmission rate R, and the length of the link m.
