In the three-way handshake that initiates a TCP connection, if the SYN request has sequence number 156955003 and the SYN-ACK reply has sequence number 883790339, what are the sequence and acknowledgment numbers for the ACK response?

Answer:

The sequence number for the ACK response is 156955004.

The acknowledgement number is 883790340.

Step-by-step explanation:

The Three-Way Handshake or a TCP 3-way handshake is a process that is implored in a TCP/IP network to create a connection between the server and client. It is a three-step process that requires both the client and server to exchange synchronization and acknowledgment packets before the real data communication process begin.

The Three-way handshake process is designed in such a way that both ends help you to initiate, negotiate, and separate TCP socket connections at the same time. It allows you to transfer multiple TCP socket connections in both directions at the same time.

Terms and their uses:

Syn: helps synchronization of sequence numbers between devices it also helpful to initiate and establish a connection.

ACK: This is what tells or confirms to the other side that it has received the SYN.

SYN-ACK: this synchronizes message from local device and ACK of the earlier packet.

FIN: Is Used to terminate a connection.

Steps for Three way handshake process.

Step 1: the client is to establish a connection with a server. It sends a segment with SYN and informs the server that the client should start communication, and with what should be its sequence number.

Step 2: The server will respond to the client request with SYN-ACK signal set. ACK helps you to signify the response of segment that is received and SYN signifies the sequence number it should able to start with the segments.

Step 3: The client acknowledges the response of the Server, and they both create a stable connection will start the actual data transfer process. This is the final step.
