Consider a three-switch network where the switches are connected to each other via 560 kbps links.
Switch 1 is serving 5 workstations each offering packets at a rate of 20 packets/sec, switch 2 is serving 8 workstations each offering packets at a rate of 18 packets/sec, and switch 3 is serving 10 workstations each offering packets at a rate of 25 packets/sec (with all packet lengths of 1024 bits). The switches are expected to send their entire traffic to its neighbor switch (1 to 2, 2 to 3 and 3 to 1). First, draw a network diagram including the queues. Next, calculate the load on each switch, utilization of each of the three links, and average number of packets in each queue.
