Transmission Control Protocol $($TCP$)-$Consider the following plot of TCP window size as a function of time.

Assuming TCP Reno is the protocol experiencing the behavior shown above, answer the following questions. In all cases, you should provide a short discussion justifying your answer.

I. Identify the intervals of time when TCP slow start is operating.

II$.$ Identify the intervals of time when TCP congestion avoidance is operating.

III. After the $16$ th transmission round, is segment loss detected by a triple duplicate ACK or by a timeout?

IV$.$ After the $22$nd transmission round, is segment loss deteeted by a triple duplicate ACK or by a timeout?

V$.$ What is the initial value of Threshold at the rst transmassion round?

V$1.$ What is the yalue of Threshold at the $18$th transmission round?

VII During what transmissice round is the $70$th segment sent?

VIII Assuming a packet loss is detected after the $26$ th round by the receipt of a triple duplicated ACK, what will be the values of the congestion control window size and of Threshold?
