Question

Traffic intensity is one of the important ratio which gives an insight into the queuing delays.

Discuss traffic intensity and its impact on the queue’s behaviour of a router for the following

cases: (i) Traffic Intensity >1 (ii) Traffic Intensity < 1 (iii) Traffic Intensity =1. (You have to

explain your answer with the help of mathematical equations and graph).

Answer 1

A traffic intensity of more than 1 or (Traffic Intensity >1 ): This implies that that the speed at which bits come is above the rate bits can be transmitted and queuing delay will increase without bound as shown below:
