1) (25 pоints) Suppоse twо hosts A аnd B аre sepаrated by the distance d = 2, 000 kilometers and are connected by a direct link with transmission bit rate R = 100 Mbit/s. The link has a propagation speed of s = 2 · 108 meters/second. a) Evaluate the propagation delay tprop. b) What is the bandwidth-delay product R · tprop? c) Evaluate the end-to-end delay (transmission delay plus propagation delay) for transmitting a file with F = 10, 000, 000 bits from A to B. d) During the transmission considered in c) what is the maximum number of bits in the link? e) What is the width of a bit on the link? f) Now suppose you can vary the transmission bit rate R. How do you need to set R such that the last bit leaves the source exactly when the first bit reaches the destination? Suppose that file size F = 10, 000, 000 bits, propagation speed s = 2 · 108 m/sec, and distance d = 2, 000 km are unchanged.
