Analysis of TCP three-way handshake and four-way handshake, analysis of tcp three-way handshake Reprinted from http://www.jellythink.com/archives/705What is TCP? I am not going to elaborate on what TCP is. When you see this article, I think you also know the concept of TCP and want to have a better understanding of TCP work, let's continue. It is just a super-tro

TCP three handshake and four wave of the whole process TCP is the host to the host Layer Transmission Control Protocol, providing a reliable connection service, with three handshake confirmation to establish a connection: Bit code is the TCP flag bit, there are 6 kinds of representations: SYN (Synchronous establish connection) ACK (acknowledgement indicates response, confirmation) PSH (push indicates data
This is a network programming interview key points of knowledge, summed up: to establish a connection-three times handshake TCP establishes a connection between the server and the client through a three-time handshake.The so-called three-time handshake (three-way handshake) means that when a TCP connection is established, the client and server are required to sen

[Linux] linuxtcp three-way handshake and four-way handshake1. What is TCP? 7-layer OSI model TCP is on the fourth layer -- the Transport layer, and the data on the fourth layer is the Segment-> message. IP address on Layer 3-Network layer, data on Layer 3 is called Packet-"data Packet ARP on the second layer -- Data Link layer; on the second layer, we call it Frame-"Frame. When data is sent from the application layer, header information is added
TCP (Transmission Control Protocol) Transmission Control Protocol TCP is the transmission control protocol used by the host to control the host layer. It provides reliable connection services and uses three handshakes to establish a connection: The location code is the TCP flag. There are 6 types of tags: SYN (synchronous established online) ack (acknowledgement confirmation) Psh (push transfer) Fin (finish ended) RST (reset) URG (Urgent urgent) Sequence Number acknowledge number (confirmation n
TCP three-way handshake and four-way handshake Three-way handshake:Three handshakes are required to establish TCP. The Client sends the connection request message first. The Server segment receives the connection and replies to the ACK message, and allocates resources for the connection. After the Client receives the ACK packet, it also generates an ACK packet to the Server segment and allocates resources s

The TCP/IP state machine, as shown in:In the TCP/IP protocol, the TCP protocol provides a reliable connection service with a three-time handshake to establish a connection, as shown in 1. (SYN packet indicates flag bit SYN=1,ACK packet indicates flag bit Ack=1,syn+ack package represents flag bit syn=1,ack=1)(1) First handshake: When a connection is established, client A sends a SYN packet (SEQ_NUMBER=J) to
Document directory In TCP/IP, TCP provides reliable connection services and uses three handshakes to establish a connection, as shown in figure 1. In TCP/IP, TCP provides reliable connection services and uses three handshakes to establish a connection, as shown in figure 1.
