Consider the following Figure. Assuming TCP Reno is the protocol experiencing the behavior shown below, answer the following questions.

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

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

After the 10th transmission round, is segment loss detected by a triple duplicate ACK or by a timeout?

After the 22nd transmission round, is segment loss detected by a triple duplicate ACK or by a timeout?

What is the value of ssthresh at the 15th transmission round?

What is the value of ssthresh at the 24th transmission round?

During what transmission round is the 90th segment sent?

Assuming a packet loss is detected after the 25th round by the receipt of a triple duplicate ACK, what will be the values of the congestion window size and of ssthresh?
