Course Introduction：TCP connection, three-way handshake: The three-way handshake and four-way dissolution process of the TCP connection: When the client and server use the TCP connection to transmit data, they need to go through the three-way handshake to establish the connection and the four-way handshake to disconnect. As shown in the figure below, the above figure describes the detailed process of TCP connection from establishment to disconnection. The specific message details will be discussed below. During the TCP three-way handshake to establish a connection, the client first sends a request packet with SYN=1 and Sequence=p to the server. If the server agrees to grant the client the link, it sends a response packet with ACK=p+1, SYN=1, and Sequence=q. Finally received the service on the client

Course Introduction：In order to accurately deliver data to the destination, the TCP protocol uses a three-way handshake strategy. After the data packet is sent out using the TCP protocol, TCP will not ignore the situation after the transmission. It will definitely confirm to the other party whether it was successfully delivered. TCP flags are used during the handshake: SYN and ACK. The sending end first sends a data packet with the SYN flag to the other party. After receiving it, the receiving end sends back a data packet with the SYN/ACK flag to convey confirmation information. Finally, the sending end sends back a data packet with an ACK flag, indicating the end of the "handshake". If shaking hands

Course Introduction：The TCP three-way handshake is a key step in establishing a TCP connection. In this process, through the interaction of three message segments, the client and server confirm each other's identity and communication capabilities, thereby establishing a reliable connection. This mechanism ensures the reliability and integrity of data transmission, but it also brings time overhead, which needs to be weighed and optimized in practical applications.
