data communication

 
Tme lert O.53.J
Consider the network in the figure below. Calculate the total delay (latency) for a message of stze 4 Megabits
that is being sent from PCO to PC1. Assume any device will take a queuing time of 3 us and a processing time
of 1 us. The distance between any two adjacent routers is 1000 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 message is sent in one frame.
