When a connection is established, each end allocates a buffer to store the received data

TCP/IP three handshake four times waving, is very important, this link and the closure process is also very simple, but why is three times handshake. And why wait for the 2MSL state. Most people may have heard the question, this blog on the synthesis of "TCP/IP Detailed: Volume One" to analyze the reasons: Here is a look at the TCP three handshake four times the

characters, so fill the bit so that the header length becomes the whole word count.Data: The data portion of the TCP message segment is optional. When a connection is established and a connection is terminated, the message segments exchanged by both parties are only TCP headers. If a party has no data to send, it also uses the header without any data to confirm the received data. In many cases where the timeout is processed, a segment of the message without any data is also sent.TCP Three-time

TCP (transmission Control Protocol Transmission Control Protocol ( TCP /wireless) is a connection-oriented, reliable, byte-stream-based transport-layer Communication agreement defined by the IETF RFC 793. In the simplified computer network OSI model, it accomplishes the function specified by layer Fourth transport layer, and the User Datagram Protocol (UDP) is Another important transport protocol in the same layer. In the Internet Protocol family (Internet Protocol suite), the TCP layer is the

OSI Computer Network 7-layer modelTCP/IP layer four network modelThe transport layer provides logical communication between applications (end-to-end), the network layer provides host-to-host communication, and the transport layer provides reliable services.The usual handshake in TCP refers to the definition of a connection and the process of establishing a connection. The IP protocol is not connected, but TCP is linked.Port : The data link layer relie

A few days ago, the lab group threw out a question:can the three handshake process built by a TCP connection carry data? suddenly found that they really do not know this problem, on weekdays with tcpdump or Wireshark grab bag, never notice the third handshake ACK Packet has no data. So hurriedly with NC with Tcpdump grabbed a few packs want to test. But after many experiments, it was true that the third

= Initiator req+1, paired at both ends. Tertiary handshake The so-called three-time handshake (three-way handshake) establishes a TCP connection, This means that when a TCP connection is established, a total of 3 packets are sent to the client and the server to confirm the connection establishment. In socket programming, this process is triggered by the client

TCP Three-time handshakeTCP connections are required before the client and server send HTTP request responses to each other, because HTTP is a non-connected, stateless protocol with no concept of connectivity, only the concept of request and response. Requests and responses are actually packets, and they need a transport channel for transmission, which is the channel created by TCP. So how is this channel created? Is through a TCP three-time handshake.What is a TCP three-time
