What is the process of establishing a TCP connection using a three-packet handshake?

How to reset tcp/ip protocol in win10? In fact, the method is very simple. Users can directly enter the command prompt, and then press the ctrl shift enter key combination to perform the operation, or directly execute the reset command to set it up. Let this site do the following. Let us carefully introduce to users how to reset the TCP/IP protocol stack in Windows 10. Method 1 to reset the tcp/ip protocol stack in Windows 10. Administrator permissions 1. We use the shortcut key win R to directly open the run window, then enter cmd and hold down the ctrl shift enter key combination. 2. Or we can directly search for command prompt in the start menu and right-click

TCP is a type of computer network communication protocol and a connection-oriented transmission protocol. In Java application development, TCP communication is widely used in various scenarios, such as data transmission between client and server, real-time transmission of audio and video, etc. Netty4 is a high-performance, highly scalable, and high-performance network programming framework that can optimize the data exchange process between the server and the client to make it more efficient and reliable. The specific implementation steps of using Netty4 for TCP communication are as follows: Introduction

TCP client A client sample code that uses the TCP protocol to achieve continuous dialogue: importsocket#Client configuration HOST='localhost'PORT=12345#Create a TCP socket and connect to the server client_socket=socket.socket(socket.AF_INET,socket .SOCK_STREAM)client_socket.connect((HOST,PORT))whileTrue:#Get user input message=input("Please enter the message to be sent:&

The "connection-oriented" mentioned here means that you need to establish a connection, use the connection, and release the connection. Establishing a connection refers to the well-known TCP three-way handshake. When using a connection, data is transmitted in the form of one send and one confirmation. There is also the release of the connection, which is our common TCP four wave waves.

Among the TCP communication parties, for the convenience of description, the communication parties are replaced by A and B in the following. According to the TCP protocol, if B continues to send data after A closes the connection, B will receive A's RST response. If B continues to send data, the system will send a SIGPIPE signal to inform that the connection has been disconnected and stop sending. The system's default processing behavior for the SIGPIPE signal is to let process B exit. The default processing behavior of the operating system for the SIGPIPE signal is very unfriendly. Let us analyze it. TCP communication is a full-duplex channel, which is equivalent to two simplex channels, and each end of the connection is responsible for one. When the opposite end "closes", although the intention is to close the entire two channels, the local end only receives the FIN packet. According to the provisions of the TCP protocol, when a

Why is there this blog about using one TCP connection to send multiple files? I have been reading some related things recently. There is no problem in simply using Socket for programming, but this only establishes some basic concepts. Still nothing can be done about the real problem. When I need to transfer files, I find that I seem to have just sent the data (binary data), but some information about the file is lost (the file extension). And each time I can only use one Socket to send one file, there is no way to send files continuously (because I rely on closing the stream to complete sending files, which means that I actually don’t know the length of the file, so I can only send files as one Socket connection represents a file).

TCP and IP are two different protocols in the Internet: 1. TCP is a transport layer protocol, while IP is a network layer protocol; 2. TCP provides functions such as segmentation, sorting, confirmation and retransmission of data packets. , and the IP protocol is responsible for providing source and destination addresses for data packets; 3. TCP is a connection-oriented protocol, while the IP protocol is connectionless; 4. TCP also provides flow control and congestion control.

There was once such a classic interview question: What happens in the process from the URL being entered in the browser to the page being displayed? I believe that most students who have prepared can answer it, but if you continue to ask: If the received HTML contains dozens of image tags, in what way, in what order, how many connections are established, and what protocol are used to download these images? What about?
