Assume that MSS = 1000 bytes and the slow start threshold is 20,000 bytes. Suppose that TCP is in Slow Start and its window size is currently W = 8. %3D a) After receiving 8 non-duplicate ACKS, what is TCP's window size? b) After these 8 non-duplicate ACKS, packet loss is detected through timeout. What is TCP's window immediately after the loss? What is the slow start threshold? c) Specify the window size for each of the 5 RTTS (one value of W per RTT) following the loss in part b. No additional packet loss occurs
