In a network as depicted in the below figure, consider client and server are connected by a

network comprising K routers. The distance between two consecutive devices is d $=6000$

kilometers, and data transmission occurs at the speed of light, $3\backslash$times $108$ meters per second.

The link capacity of each link is R $=10$ Mbps$.$ Assuming processing delay and queueing delay

are negligible and routers forward the packets based on the store$-$and$-$forward strategy.

Calculate the required time from the moment A transmits its first bit until the receiver

receives the last bit of a file sized at $2\mathrm{.}5$ MB if K $=12.(25$ points$)$

In this question, we want to measure the delay between your computer and a random server

through the traceroute$/$tracert command. Please select a random server that you would like

to connect to$,$ run the traceroute command, and answer the following questions. You should

attach the relevant screenshot for this question. Without a screenshot, your score will be

zero. $(10$ points$)$

$1.$ What is your selected server? How many routers are between your computer and

that server? $(2$ points$)$

$2.$ Which information can you get at each step? $(2$ points$)$

$3.$ Is there a significant increment in delays between two consecutive routers? $(2$ points$)$

$4.$ Is there any row that retunes just $***?$ Why? $(4$ points$)$
