Extracted text: TCP congestion control mechanisms consist of three operating states: Slow Start, Congestion Avoidance, and Fast Recovery. Assume that the figure shows the behavior of TCP Reno which implements Fast Recovery. (In the figure, transmission round 1 refers to the interval that starts with the point where the horizontal axis equals 1 and ends with the point where the horizontal axis equals 2.) Answer the following questions. 45 40 35 30 25 20 15 10 5- 0+ 0 2 4 6 8 10 12 14 16 18 20 22 24 26 Transmission round Congestion window size (segments)
