(b) Fig. 1 illustrates the evolution of TCP's congestion window (cwnd). The unit of time (on the x-axis) is equal to the Round Trip Time (RTT). Reconstruct the sequence of events that explains TCP's cwnd using the following prompts. 15 10 www 5 10 15 20 Time unit (in RTT) 25 30 35 40 Figure 1: TCP Congestion Window Evolution (i) Give the time indices when TCP is in slow start. (ii) List the time indices when TCP is in congestion avoidance mode. (iii) Give the time indices when TCP is in fast recovery. (iv) List the time indices corresponding to packet loss via timeout. (v) List the time indices corresponding to packet loss via triple ACK. (vi) Give the time indices when the value of ssthresh changes.
