Reprinted from Http://dotnet.chinaitlab.com/ASPNET/731870.html Many people think that the server socket in the network application should not use synchronous sockets. Yes, in most cases it is, but there are also scenarios where we might get more results with a sync socket. We can consider using synchronous sockets for the following two scenarios. One, the number of clients is less than: A smaller number ref
Socket programming practices in Linux (2) introduction to basic socket programming APIs What is Socket? Socket originated from Unix, and one of the basic philosophies of Unix/Linux is "Everything is a file". You can use the "open-> read/write-> close" mode to operate. Socket
Hp-socket is a common set of high-performance Windows Socket component packages that contain server-side components (IOCP models) and client components (Event Select model), which are widely used in Windows platform TCP communication systems. Hp-socket the communication layer is fully encapsulated, the upper application does not need to pay attention to any detai
First, socketThe English literal of the socket is "hole" or "socket". As the BSD UNIX process communication mechanism, take the latter one meaning. usually alsoCalled sockets, which describe IP addresses and ports, is a handle to a communication chain that can be used to communicate between different virtual machines or different computers. Hosts on the internet typically run multiple service software, whil

Valid port: 0 ~ 65535 0 ~ 1024 is used or reserved by the system. Do not use port 1024 during development. Transmission Protocol [communication r
1. basic structure of socketsstruct SOCKADDRThis structure is used to store socket addresses.Data definition:struct SOCKADDR {unsigned short sa_family; /* Address family, AF_XXX */Char sa_data[14]; /* Protocol address for bytes */};Sa_family in general, are "afinet".Sa_data contains the number of addresses, ports, and sockets for some remote computers, and the data inside it is mixed in one cut. To deal with Struct sockaddr, the programmer builds anot
Network sockets are also called an Internet socket, which in English is a Web socket. In a network, a socket plays a role as a socket, an endpoint that can be connected to other sockets in the network. Sockets allow two of processes to communicate, which may run on the same machine or on different machines. More preci
Image Description of the SOCKET protocol The original meaning of socket is "hole" or "socket ". Here we use the 4bds UNIX Process Information mechanism, take the latter meaning. Socket is very similar to a telephone outlet. Take a national-level telephone network as an example. The two sides of a telephone call are equ
Socket programming refers to a complete set of API programming about sockets, not just the use of socket () system calls, but also a complete set of functions around this system call. Here we will start from the basics and learn how to write the socket program initially. host byte order and network byte order To learn about s

server-side background service. The combination of a port number and an IP address is called a network socket (socket). Java language in the implementation of C/s mode, sockets are divided into two categories: On the server side, the ServerSocket class supports the underlying network traffic; On the client side, the socket class supports the underlyin
Php socket programming and socket programming 1. Prerequisites I have never seen how many people use the socket module of php to do some things. Maybe everyone has positioned it within the scope of the script language, but in fact, the php socket module can do a lot of things, including ftplist, http post submission, s
SocketI. OverviewSockets are also commonly referred to as "sockets," which describe IP addresses and ports, and are a handle to a chain of communication, where applications usually make requests to the network through "sockets" or respond to network requests.Sockets originate from UNIX, and one of the basic philosophies of unix/linux is "Everything is file", and the file is operated with "open" "Read and Write" "Off" mode. Socket is an implementation
Asynchronous Client Socket Example The following example program creates a client that is connected to the server. The client is generated with an asynchronous socket, so it does not suspend execution of the client application while waiting for the server to return a response. The application sends a string to the server and then displays the string returned by the server in the console. C# Using System
The socket mechanism provides two socket option interfaces to control the behavior of sockets. An interface is used to set options, and another interface is used to allow us to request the status of the option. We can get and set three kinds of options. 1. General options that can work on all socket types. 2. Options for managing at the
