Consider the behavior of TCP Tahoe (blue curve) shown in the figure and answer the following questions. Congestion window (in segments) 16- 14- 12- 10- 8 10 4 0 ssthresh -TCP Tahoe 3 4 -TCP Reno ssthresh 5 6 7 8 9 10 11 12 13 14 15 Transmission round a. Identify the intervals of time when TCP slow start is operating. (10 Points) P 1 to 4 and 9 to 12 b. Identify the intervals of time when TCP congestion avoidance is operating. (10 Points 4 and 9. c. What is the initial value of ssthresh at the first transmission round? (10 Points) 8. d. Why does the value of ssthresh change to 6 at the 8th transmission round? (10 Points) e. Suppose the network capacity (measured in number of segments) is 9 segments af- ter the 15th transmission round. What are the values of the congestion window from the 16th transmission round to the 20th transmission round? What is the value of ssthresh? (10 Points)spispisep wwwwwwwwwwwwwwwww.
