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.
