Assume there are two end hosts separated by100 kilometers that are connected together by a transmission link operating at 100 Mbps. You can assume the propagation speed of the transmission link is 2.4x10^8 meters per second.

1. Calculate the bandwidth-delay product , R*dprop
2. Consider sending a file of 1 Gbit between the two end hosts. Assuming the file is sent continuously as one large message, what is the maximum number of bits that will be in the link at any given time? Provide an interpretation of the bandwidth-delay product.
3. What is the width (in meters) of a bit in the link?
4. Derive a general expression for the width of a bit in terms of the propagation speed s, the transmission rate R, and the length of the link m.
5. How long does it take to send the file, assuming it is sent continuously?
6. Suppose the file is broken up into 100 packets with each packet containing 10 Mbits. Suppose that each packet is acknowledged by the receiver and the transmission time of an acknowledgment packet is negligible. Finally, assume that the sender cannot send a packet until the preceding one is acknowledged. How long does it take to send the file?
