Assume that two hosts are directly connected via a submarine optical fiber cable, which goes from Los Angeles, CA to Shanghai, China. The cable length is 14,000 km. The bandwidth of the cable is R = 100 Gbps. Assume that the signal propagation speed in the cable is 2.0*10^8 m/s. Answer the following questions. (Make sure to have the correct number and unit for your answers whenever applicable.) a. What is the one-way propagation delay, dprop, between the two nodes? b. What is the Round Trip Time (RTT) between the two hosts? c. Calculate the bandwidth-delay product, i.e., R * dprop.
