Suppose two hosts A and B are connected via a router R. The A-R link has infinite bandwidth; the A-R link has infinite bandwidth; the R-B link can send one packet per second. R's queue is infinite. Load is to be measured as the number of packets per second sent from A to R. Sketch the curves for throughput, delay, and power, each as a function of load.
