Fill the following graph showing the congestion window size for TCP Reno assuming that the initial threshold value is $8.$ There occurs three loss events: One loss event will occur due to a time$-$out event when the window size is $11$ and another two loss events will occur due to the triple$-$duplicate ACK events when the transmission round is $11$ and $15.$ Recall that, TCP Reno employs a fast recovery method that skips the slow start method after a loss event occurs.

Fill in the following graphs and explain the graph in detail behind the shape of the graph with your rationale and assumption with proper justifications and calculations.

note: answer this as like student on exam..
