through socket

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

resolve it.5. The main socket type in the TCP/IP protocol family is now a stream socket (using the TCP protocol) and datagram sockets (using the UDP protocol), where the application can only send information at the maximum length of 65,507 bytes at a time through datagram sockets.6. A TCP/IP socket is uniquely determined by an Internet address, an end-to-end pro

1. TCP-based Network Program It is the general process of a TCP-based client/server program: After the server calls socket (), BIND (), and listen () to complete initialization, it calls accept () to block and wait, and is in the listening port State. After the client calls socket () to initialize, call connect () to issue SYN segments and block wait for the server to respond, the server responds to a SYN-

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

NET socket development today, let's talk about the application of synchronous sockets in the development of. NET network applications, many people think that the service socket of the network application should not use synchronous

socket interpretation, HTTP and socket long connection and short connection difference. TCP/IP TCP/IP is a protocol group that can be divided into three levels: Network layer, Transport layer and application layer. At the network layer are IP protocols, ICMP protocols, ARP protocols, RARP protocols, and BOOTP protocols. There are TCP protocols and UDP protocols in the transport layer. ； In the applicat

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 general, the socket can be divided into TCP sockets and UDP sockets, further, can also be divided into server-side sockets and client sockets. In this section we first focus on the TCP socket server-side Socket,java in the ServerSocket class corresponding to it, this class is mainly used to create a socket service o

HP-socket is a set of universal high-performance Windows Socket component packages, including the server component (iocp model) and the client component (event select model). It is widely used in Windows TCP communication systems. HP-socket fully encapsulates the communication layer, and upper-layer applications do not need to pay attention to any details of the

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

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

Solution:For a socket object, use the write method (writebyte (), writeutfbytes (), and other methods .) first write data to the cache area, and then use the flush () method to send data. for xmlsocket objects, use the send () method. Discussion:The methods for sending data from the socket and xmlsocket classes to the socket server are different. Let's first look
