Because of the connection-oriented nature of TCP, a connection setup phase is required at the beginning of each session, as well as a connection tear-down phase at the end of the session. Enumerate the events below in the order they occur as host A opens a TCP connection to host B, transmits data and then closes the connection. Write a 1 next to the event that occurs first and continue like that until all occurring events are enumerated (the first event has been enumerated for you). You may assume that no segments are lost. Also indicate at which host the event happens. Please note that there might be events listed below that are not a part of the above data transfer and hence should not be enumerated. Order Host Event Send an ACK segment Do the rest of the data exchange Close the connection Send a FIN segment 1 A Send a SYN segment Send a FIN-ACK segment Send a RST segment Send a SYN-ACK segment Enter the TIME-WAIT state Send an ACK+DATA segment Close the connection
