Consider a TCP client and a TCP server running on two different machines. After completing data transfer, the TCP client calls close to terminate the connection and a FIN segment is sent to the TCP server. Server-side TCP responds by sending an ACK which is received by the client-side TCP. As per the TCP connection state diagram(RFC 793), in which state does the client side TCP connection wait for the FIN from the server-side TCP?
  • a)
    LAST-ACK
  • b)
    TIME-WAIT
  • c)
    FIN-WAIT-1
  • d)
    FIN-WAIT-2
Correct answer is option 'D'. Can you explain this answer?

Consider a TCP client and a TCP server running on two different machin...
Client has sent FIN segment to the server and moves to FIN-WAIT-1, i.e. waiting for the ACK for own
FIN segment. There are two possibilities here :

If Client receives ACK for its FIN then client will move to FIN-WAIT-2 and will wait for matching
FIN from server side. After receiving the FIN from server, client will send ACK and move to TIME-WAIT
state.
Client has sent FIN segment but didn’t get ACK till the time. Instead of ACK, client received FIN
from server side. Client will acknowledge this FIN and move to CLOSE state. Here Client will wait for
the ACK for its own FIN. After receiving ACK, client will move to TIME-WAIT state.
Here we encounter First Case.
So, the solution is (D).

Explanation:

Client-Side TCP Connection State Transition:
- After sending a FIN segment to terminate the connection, the client-side TCP connection enters the FIN-WAIT-2 state.
- In this state, the client-side TCP waits for the ACK from the server-side TCP for the FIN segment it sent.

State Explanation:
- FIN-WAIT-2 state indicates that the client has received the FIN from the server and acknowledged it.
- The client is now waiting for the server to send an ACK for the FIN it received.

Final Note:
- The client-side TCP will remain in the FIN-WAIT-2 state until it receives the ACK from the server, after which it transitions to the CLOSED state and the connection is terminated.
