Question

1.Suppose two nodes are communicating 1500-byte frames at 54 Mb/s and are 100 m apart. How much time passes from when one node starts sending a frame and the other completely receives the frame?

2.Suppose two nodes are communicating 1500-byte frames at 1 Mb/s and are 40k km apart. How much time passes from when one node starts sending a frame and the other completely receives the frame?

3.Suppose two nodes are 1000 km apart and one has to send the other a 1000-bit frame in at most 5 ms. What is the minimum throughput that will achieve this?

4.Suppose a 100 Mb/s LAN uses 1500 byte frames. If frames arrive at the rate of a frames per second, at what value of a does the the LAN saturate?
