Learn All About TCP Handshake


TheTCP Handshake is one of the most important protocols in the world of computing. It’s responsible for establishing a connection between two devices, and it’s essential for many activities such as online gaming and file downloads. In this blog post, we will learn all about the handshake and what it does. We will also explore some of the different variants of the handshake and how to use them properly. By the end, you will have a much better understanding of this important protocol.

What is TCP Handshake?

The TCP Handshakeis a process that is used to establish a communication link between two systems. The  handshake begins with the sender sending a window update message to the receiver. This message contains information about the size of the available window, which allows the receiver to determine how much data it can send without waiting for the sender to send more data.

The next step in the handshake is for the sender to send an SYN packet. This packet contains information about the receiver’s name and port number and asks permission from the receiver to initiate a connection. The receiver will then respond with an SYN-ACK packet, confirming that it received and understands the request from the sender.

Next, the sender sends a TCP segment containing data to be sent over the communication link. The recipient will then acknowledge receipt of this data by sending back a TCP segment containing its acknowledgment number. Once both segments have been received, both sides will release their resources, sign off of each other, and close down their connections.

What are the benefits of  TCP Handshake?

TCP handshake is the first step of communication between two computers. During this handshake, the two systems determine their port numbers and other necessary information. handshake also contains a sequence number that is incremented for each packet sent during the handshake. If any error occurs during the handshake, it can result in lost packets and damaged connections.

handshake is essential for establishing a connection between two systems. Without it, communication would be impossible.

handshake ensures that both systems have initialized and are ready to start sending data.

The sequence number helps keep track of the order in which packets were sent and received. It helps ensure that data is not lost or corrupted if one system fails before the other finishes its part of the handshake.

By correctly completing  handshake, you can minimize chances of experiencing network issues or connection failures

How  handshake works?

 Handshake is a process by which two computers establish a connection. handshake starts with the sending computer sending an SYN packet to the receiving computer. The SYN packet contains the sequence number, flags, and ACK field from the previous packet that was sent. The receiving computer then sends back an acknowledgment (ACK) packet that contains the same sequence number, flags, and ACK field as in the previously received SYN packet. After both computers have sent and received their acknowledgments, the connection can be established.

How to configure  handshake in your network?

In this tutorial, we are going to talk about how to configure  handshake in your network. The handshake is a process that is used between two hosts during the TCP connection establishment phase. It is essential for both hosts to successfully complete the handshake in order for the TCP connection to be established.

There are three main steps involved in the handshake: SYN, ACK, and FIN. The SYN packet is sent from the client (server) to the server and it marks the beginning of the handshake process. The ACK packet is sent by the server and it confirms that it has received the SYN packet from the client. The FIN packet is sent by the server as a response to the ACK packet and it signals that the TCP connection has been successfully established.

It is important to note that if any of these packets are not received or processed correctly, then the TCP connection will fail and no data will be transmitted between the hosts. In order to configure  handshake on your network, you first need to determine which protocol your network uses for TCP connections. If you are using a TCP/IP-based network, then you will need to use the tcpip commands in order to configure  handshake on your network. If you are using an IP-based networking scheme such as Wi-Fi, then you will not need any special commands in order to configure  handshake on your network; however, you will still need to enable IP forwarding so that traffic directed towards your


 handshake is the process that helps two computers establish a connection. handshake ensures that data sent between the computers is properly formatted and error-free, so that both machines can understand each other.
