Question-1 (25 points) Consider the graph below modeling behavior experienced by a TCP protocol. The graph should be read to mean that Congwin-1 during round 1, Congwin-2 during round 2, Congwin-4 during round 3, etc. 25 o 20 15 1 2 3 45 6 7 8 9 1011 12 13 14 15 16 17 18 19 20 21 Transmission round Answer the following questions. In all cases give a short explanation as to how you derived your answer a) Is this TCP RENO or TCP Tahoe? b) A loss event occurs during the 11 th transmission round. What type of loss event occurs? c) A loss event occurs during the 17th transmission round. What type of loss event occurs? d) What is the initial value of Threshold during the first transmission round? e) Suppose there is no loss event during the 21st transmission round. What will the value of Congwin be during the 22nd round
