Consider the queuing delay in a router buffer. Let f denote traffic intensity; that is, l < 1. Suppose that the queuing delay takes the form lL/R (1 -I) for f < 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.
