The network in Fig. $9$ is considered where source $1$ sends packets at a rate of $7000$

packets per second, and source $2$ at a rate of $3500$ packets per second. Both sources

send packets of average size $1250$ bytes. Router R$1$ can forward packets of either source

at $50$Mbits$/$sec on each of its outgoing links. Router R$2$ can forward packets of either

type at $100$ Mbits$/$sec$.$

the distribution of outgoing traffic for routers R$1$ and R$2$ is described in Table $4.$ Table $4$: Distribution of outgoing traffic for routers R$1$ and R$2$ From Router R$1$ to: Sink $1$ R$2$ Source $150\%50\%($i$)$ Calculate the average number of packets in each queue, assuming M$/$M$/1$ queues. $($ii$)$ Round these values to the nearest integer and assign the results for each queue to be the finite capacity of the queue. Calculate the overall average delay experienced by packets sent by source $1$ and arriving in sink $2$ or sink $1,$ and the average delay experienced by packets sent by source $2$ and arriving in sink $2.$
