TCP Congestion Control consider the following plot of congestion window size as a function of transmission round. Assume that TCP Reno is used. TCP Reno 25 5 6 8 12 14 6 18 20 time (RTT) (a) (2 pts) Identify the time intervals of TCP slow start. (b) (3 pts) Identify the time intervals of TCP congestion avoidance. (c) (d) (2 pts) After the 10h RTT, is the segment loss detected by a triple duplicate ACK or by a (e) (6 pts) After the 10th RTT, when the segment loss is detected, what will the values of ssthresh (2 pts) What is the initial value of ssthresh at the first transmission round? timeout? and cwnd immediately update to? After that, if a new ACK is received (at 11h RTT), what will the cwnd value change to? timeout? After that, what will the values of ssthresh and cwnd update to? segment is 15 KBytes, and RTT = 1sec. (D (6 pts) After the 14th RTT, is the segment loss detected by a triple duplicate ACK or by a (8) (4 pts) Estimate the average throughput for the time interval [0, 20RTT]? Assuming each
