Network protocol seven-tier structure:What is a socket?The socket (socket) is the end of the two-program data exchange between the two-way channel, which can be understood as an interface. Using socket programming is also known as network programming, and sockets are just interfaces that are not network communication p

Principle: The client uses regular http to request webpage requests to execute javascript scripts and open a connection to server. when there is new information, the server and client can send information to each other (Real-time traffic from the server to the client and from the client to the server HTML5 WebSockets client Description: readyState: CONNECTING (0): indicates that no connection has been established; OPEN (1): A connection has been established for communication; CLOSING (2): CLOSIN

request ends.Ii. Basic socket In order to better illustrate the socket programming principles, we will provide several basic sockets, which will be described in more detail in the future.1. Create a socket-socket ()Function: Create a new socketFormat: Socket Pascal far

The sample program is a synchronous socket program, the function is very simple, just the client sends a message to the server, the server returns a message to the client, here is just a simple example, is a basic socket programming process, in the next article, will record the synchronization and asynchronous sockets, and their differences.The following is a simple procedure for the sample program descript

Basic Application of socket. io tutorial (2) socket. io tutorial Preface Socket. IO supports timely, bidirectional, and event-based communication. It can work on every platform, every browser, and every device, with the same reliability and speed. Real-time analysis: pushes data to clients, which are expressed as real-time counters, charts, or log customers.

In the article Java Socket Chat room programming (i) the use of socket to implement chat message push we talked about how to use the socket to allow the server and the client to pass messages between the message to achieve the purpose of the push message, and then I will write out how to let the server establish client and client communication. In fact, it is to

Socket address In Java, you can use the host name or host address to identify a network address, for example, www.baidu.com and 115.239.210.26, but the host name must be resolved to a digital address for Communication (DNS ), this process will take a certain amount of time, so we generally use a digital address in the program. In Java, inetaddress represents a network destination address, including host name and number address information. It has two

Summary of Socket-based simple chat tools (original) and socket chat tools During this time, I can't help but try to write a summary to encourage myself to study hard and write poorly. Please advise me! The following is a simple program for sending messages and files. First, the server needs to prepare two sockets and two threads as follows: // Communicate with the client private

In many cases, we need to use a fixed IP and port number to communicate, and by default, the client side of the port number is not fixed, by the system automatically allocate idle port number to communicate; But in many cases, some services to write more stringent, only to receive fixed IP and port number of data, we all know that IP address we can guarantee that the same, but the port number by default is not possible to achieve the same, this time we need to the port number for special treatme

SIGPIPE signal in socket programming and sigpipe in socket programming I wrote a server programLinuxAnd then write the client in C ++ to perform stress testing with tens of millions of short links.However, the Server Always exits without core files. Finally, the problem is determined to call two write operations on a socket that has been closed on the peer end. T

PHP socket connects to the server template, socket server. When the socket of PHP is connected to the server template, the socket server finds that some cached data needs to be accessed by external interfaces while organizing the new framework. What is more convenient is the php interface, PHP

Before entering a variety of powerful raw socket applications, we will first explain how to establish a raw socket and how to use the established raw socket to send and receive IP packets.　　Create raw socketOn Windows, to use raw socket, you must first initialize Winsock: // Start WinsockWsadata;If (wsastartup

First, the network program based on TCP protocol The following figure is a general process for client/server programs based on TCP protocol: After the server calls the socket (), bind (), listen () completes initialization, calls the accept () blocking wait, is in the listening port state, the client calls the socket () initialization, calls connect () sends the SYN segment and blocks waiting for the se

This article address: http://blog.csdn.net/kongxx/article/details/7288896 The previous articles introduced socket communication using the Java.io and Java.net class libraries, and the following are some of the sockets that are implemented using the Java.nio class library. The Java.nio package is added to Java after 1.4 to increase the efficiency of I/O operations. The following classes or interfaces are mainly included in the NIO package: * Buffer: B
