There are 12000km between Raleigh, NC and Nanjing China. What is the shortest possible round trip time between the two places assuming a connection through one optical fiber with a propagation speed of 2e8 m/s? F. The real round trip time is considerably higher. Why? G. In line 21, what is the meaning of the * ? H. In line 7, there is a considerable increase in delay for the second and third probe (and then it subsides in line 8). Why? What's going on
