Explanation of Solution

Assume the traffic intensity in a router as I=LaR

The expression used for calculating the transmission time of each packet in terms of size of packet (L) and rate of link (R) is LR  seconds.

The queuing delay in terms of traffic intensity (I) is ILR(1-I)

The total delay is ILR(1-I)+LR=IL+L(1-I)R(1-I)=LR(1-I)
