Problems 1) Suppose a 1 Gbps fiber link is being set up between the New York and Shanghai Stock Exchanges. The distance is approximately 12,000km, and data travels over the fiber link at (2x108m/s). a) Calculate the minimum RTT for the link. b) Using the RTT as the delay. calculate the delay x bandwidth product for the link. c) What is the significance of the delay x bandwidth product computed in (b)? d) A large trade requires 100MB, what is the minimum amount of time that will elapse between when the request for the data goes out and the transfer is finished? 2) Suppose we want to transmit the message 10011010 and protect it from errors using the 4 degree polynomial x4+x2 +x1 1. Use polynomial long division to determine the message that should be transmitted a) b) Compute the CRCs above and explain whether your results are consistent with your answer above. 3) Let A and B be two stations attempting to transmit on an Ethernet network. Each has a nd. A's frames will he numhered 41. 42, and so
