5. (25 points) The slow-start-threshold ssthresh value for a TCP Tahoe system is set to 6 MSS (Maximum Segment Size). The system is in the slow-start state with congestion window cwnd = 4 Mss. A. (15 points) Calculate the values ofcwnd, ssthresh, and name the state of the system after each event at the Sender. Enter your results in the table below: a. Two ACKs arrive b. Time-out c. Two ACKs arrive events cwnd ssthresh state 4 Slowstart Initial values 2 ACKs arrive Timeout 2 ACKs arrive 3 ACKs arrive Explain why the reception of 3 duplicate ACKs indicates a lower level of (10 points) network congestion than a Retransmission Timer timeout (RTO).
