Calculate the delay x bandwidth product for the following links. Use one-way delay, measured from first bit sent to first bit received. (a) 100-Mbps Ethernet with a delay of 10 μs. (b) 100-Mbps Ethernet with a single store-and-forward switch like that of Exercise 16(b), packet size of 12,000 bits, and 10 μs per link propagation delay. (c) 1.5-Mbps T1 link, with a transcontinental one-way delay of 50 ms. (d) 1.5-Mbps T1 link between two groundstations communicating via a satellite in geosynchronous orbit, 35,900 km high. The only delay is speed-of-light propagation delay from Earth to the satellite and back.
