I need help with the question listed below and I do not want an AI answer nor a copied answer. Please show the answer in clear defined steps. Thank you in advance.

$6.$ Consider a packet of length L which is generated at a source and travels over a multi$-$hop path of N links to the destination. The links are connected by packet switches. Let d i$.$ s and r i denote the length, propagation speed and transmission rate of link i$,$ for i$=1,2....,$ N$.$ The processing delay at the source and switches for this packet is d$\_-$pri, for i$=1,2,...,$ N$.$ Assume that this packet always finds the buffer empty upon arriving at each switch on the path. $[5$ points$]$ a$)$ Quantify the queuing delay. b$)$ Derive a formula for the total end$-$to$-$end delay for this packet. c$)$ Put the end$-$to$-$end delay in its simplest form if d$\_$i$,$ r$\_-$and d pr i are all equal, i$.$e$.$ independent of $/$ for all links. d$)$ Give a formula for the end$-$to$-$end throughput for the cases in $($a$)$ and $($b$)$ above.Consider a packet of length $L$ which is generated at a source and travels over a multi$-$hop

path of $N$ links to the destination. The links are connected by packet switches. Let $d_{-}i,s_C$ and $r_{-}i$

denote the length, propagation speed and transmission bit rate of link $i,$ for $i=1,2,$dots,$N.$ The

processing delay at the source and switches for this packet is $d_{1}p{r}_{i}i,$ for $i=1,2,$dots,$N.$ Assume

that this packet always finds the buffer empty upon arriving at each switch on the path.

a$)$ Quantify the queuing delay.

b$)$ Derive a formula for the total end$-$to$-$end delay for this packet.

c$)$ Put the end$-$to$-$end delay in its simplest form if $d_{-}i,r_{-}$i and $d_{-}p{r}_{-}$i are all equal, i$.$e$.$

independent of i for all links.

d$)$ Give a formula for the end$-$to$-$end throughput for the cases: $1)$ d$\_$ i$,r_{-}$i and $d{r}_p{r}_i$ are

different for different node $i($as in the main question above$)$ and $\frac{?}{\text{b}\text{a}\text{r}}(2))\frac{?}{\text{b}\text{a}\text{r}}(d)i,r_i$ and $\frac{?}{\text{b}\text{a}\text{r}}(dr)p{r}_{-}$i are

equal for all $i($as in c$)$ above$).$
