VII. Additive Increase/Multiplicative Decrease (10 points) 3 Connection 1 throughput Use the graph above to answer the following questions about AIMD. The graph represents the offered load (in attempted throughput) of two TCP connections using AIMD for congestion control over a single link with maximum bandwidth of R bps. A. The point Z is at the intersection of X and Y. What is significant about the point and the two lines in relation to the two TCP connections? B. As the graph moves from point A, to B, to C, and finally to D, describe what is happening to the two TCP connections VII.
