Data Communication
Consider the network in the figure below. Calculate the total delay (latency) for a message of
size 5 Megabits that is being sent from PC0 to PC1. Assume any device will take a queuing
time of 3 us and a processing time of 1 µs. The distance between any two adjacent routers is
2000 meters, and the length of any other link is 100 meters. The speed of signal inside the
link is 2 x 10° m/s. For simplicity assume the bandwidth of any link is 10 Mbps, and the
