Suppose that MSS = 2000 bytes, TCP is in AIMD, and its window size is currently W = 4. Assume the slow start threshold is infinity. a) After receiving 4 non-duplicate ACKs, what is TCP’s window size? Explain your result by showing the relevant formulas. b) After these 4 ACKs, packet loss is detected through a timeout. What is TCP’s window in bytes immediately after the loss? What is the slow start threshold in bytes? c) Specify the window size for each of the five RTTs (one value of W per RTT) following the loss in part b. No additional packet loss occurs.
