Problem
1. Redraw the time-line diagram of that allow the server to delay acknowledgements and send one ACK for each full cwnd window worth of data.
2. We have not given all the rules about the transition diagram and TCP states. To be complete, we should show the next state for any state with the arrival of any type of segment. TCP should know what action to take if any of the segment types arrive when it is in any of the states. What are some of these rules?
3. What is the "half-open" case in TCP?
4. What is the "half-duplex close" case in TCP?
5. The tcpdump command in UNIX or LINUX can be used to print the headers of packets of a network interface. Use tcpdump to see the segments sent and received.
