Consider the queuing delay in a router buffer. Let *I *denote traffic intensity; that is, *I *= *La/R*. Suppose that the queuing delay takes the form *IL/R *(1 – *I*) for *I *< 1.

a. Provide a formula for the total delay, that is, the queuing delay plus the transmission delay.

b. Plot the total delay as a function of *L/R*.

Total delay = Queuing delay + Transmission delay
