Chapter 1, Problem P16P

Explanation of Solution

The average packet arrival rate can be calculated using the little’s formula from queuing theory $\text{N}\text{=}\text{a}\text{×}\text{d}$

The total number packets present in the router are packets present in the buffer and that are transmitting.

So, substitute “10+1 = 11” for “N”.

The average total delay time is $\text{queuing}\text{delay}\text{+}\text{transmission}\text{delay}$ and transmission time is inversely proportional to the transmission delay.

Thus, the queuing delay is $\left(\text{0}\text{.01+}\frac{\text{1}}{\text{100}}\right)\text{=}\text{0}\text{.01}\text{+}\text{0}$
