b) Suppose two hosts A and B are connected via a router R. The A-R link has infinite bandwidth; the R- 8 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 B. Sketch the throughput-versus-load and delay-versus-load graphs, or if a graph cannot be drawn, explain why. Would another way to measure load be more appropriate
