Problem 10 Suppose that the congestion window of a TCP connection starts from W/2 bytes, grows as specified in the congestion avoidance state until reaching W bytes, and then resets to W/2 bytes upon detecting a lost segment. Assume each segment contains MSS bytes of data, and each round takes RTT seconds. Assume W/(2MSS) is an integer. a) Give the number of rounds it takes for the window to grow from W/2 to W. b) Give the total number of bytes transmitted in a period, i.e., the period from the time the window is W/2 to just before the next time it becomes W/2 again. c) Give the loss rate (fraction of lost segments in the long run). d) Show that for W >> MSS (>>: much larger than), the average throughput is approximately 1.22 MSS RTTV
