A device involved in a Transmission Control Protocol (TCP) connection is ready to close the connection. The other device in the connection agrees. What has occurred?

Describe the situation that causes TCP to move from the state FIN-WAIT-1 to CLOSINGGroup of answer choicesThe actively closing side has sent an acknowledgment to the other side's FIN.The side of the connection that is actively closing the connection has completed the handshake and is waiting to be certain no packets remain in the network.The passively closing side has sent an acknowledgment to the other side's FIN.The side of the connection that is actively closing the connection recieves a FIN from the other side before receiving the ACK of it's own FIN.The side of the connection that is actively closing the connection has sent a FIN.

5. Illustrate the TCP connections, TCP releases with state transition diagram.

c. TCP congestion control example (c). Consider again the figure above (in question 3.7-1a), where a TCP sender sends 8 TCP segments at t = 1, 2, 3, 4, 5, 6, 7, 8 and the segment sent at t=4 is lost, as is the ACK segment sent at t=7.What does the sender do at t=16? You can assume for this question that no timeouts have occurred.Group of answer choicesInform the upper layer that the connection is terminated, and close the socket.Do nothing except increment the number of duplicate ACKs received by 1.Cut its value of cwnd in half, and retransmit the segment with sequence number 300Sets its cwnd window value to 1, and retransmit the segment with sequence number 300
