Consider sending a packet of $10M$ bytes to propagate over a link of distance $250$ Kilometers, at propagations speed $3108\frac{m}{sec}$ and transmission rate $2Kbps.$ Show your solution.

Part A$)$ What is the propagation delay?

Part B$)$ What the transmission delay?

Part C$)$ Consider the above network systems with queuing delay: $15$msec, processing delay: $8$ msec. Calculate the total end$-$to$-$end delay for a data packet transmitted across the network.

Part D$)$ Determine the throughput of the network, assuming a file transfer of $100$ MB$.$ Express the throughput in Mbps$.$

Part E$)$ Discuss how each type of delay $($transmission$,$ propagation, queuing, processing$)$ contributes to the overall end$-$to$-$end delay, and propose strategies to minimize these delays for improved network performance.
