QUESTION $1$: CONGESTION ConTrol $(30$ POINTS$)$

Q$1\mathrm{.}1(30$ points$)$ Consider the following sequence of running TCP Reno.

$-$ Time $\backslash ($ t$=0\backslash )$ : Congestion window size is $10$ packets and all are sent.

$-$ Time $\backslash ($ t$=1\backslash )$ : All packets successfully received.

$-$ Time $\backslash ($ t$=2$: $2\backslash )$ packets lost.

$-$ Time $\backslash ($ t$=3\backslash )$ : All packets successfully received.

$-$ Time $\backslash ($ t$=4\backslash )$ : All packets successfully received.

$-$ Time $\backslash ($ t$=5\backslash )$ : $1$ packet lost.

Now, using TCP Reno, what will be the congestion window size after this sequence? Explain your answer in details.
