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:

The previous article on the socket is a simple encapsulation, but because send and recv are synchronous, the real use of the time generally need to asynchronous, if the application layer itself is responsible for maintaining the asynchronous thread, the framework is not practical, so asynchronous transceiver or to have.Do not know how to say, first occupy the hole after the slowly say it.My approach to implementation:1, create Sendbuffer and Recvbuffe
Recently, there is a project is very hot, that is the live answer, received the company's task, the development of live chat room function. People online chat with each other. Previously done similar, was used by Ajax polling, this is a very expensive server. So this time began to use the socket to do, I am mainly responsible for back-end development, mainly with the front-end to do some interface.Small program front-end use of space wx.connectsocket
One, what is the socket
The socket can be viewed as a programming interface between the user process and the kernel network protocol stack.
Sockets can be used not only for interprocess communication between native computers, but also for interprocess communication between different hosts on a network.
The socket API is an abstract network programming interf
blocking, and of course listensocket.accept () to use the Try ... Catch to block out this anomaly.
The second type of approach is to use the port multiplexing, do the port binding before using Listensocket.setsocketoption (Socketoptionlevel.socket, socketoptionname.reuseaddress, 1); Set the bound port to reusable, shielding the exception directly.
I am lazy, directly using the port multiplexing, the code is less AH. Although the technology is not very understanding, but there should be some of

Over the past few days, I have been studying the socket program connected to. Net by Delphi, and finally made some progress.
Requirements:
The server intercepts the first four bytes and converts them to numbers. The second digit is the Business Code. It determines which business logic to call.

Socket : A communication bridge between different hosts in the network, the network communication software function that people use is based on socket socket as communication bridge.Addressing: In Winsock, users can use a unified socket address structure in the TCP/IP address family To resolve problems that may occur i
TCP Sockets
Allows communication between processes through a network, or through loopback, to communicate between local processes. UNIX Sockets
Allows communication between processes that are running locally. Analysis
As you can see from the picture above, the UNIX socket reduces the unnecessary TCP overhead, and TCP needs to go through the loopback and request temporary ports and TCP-related resources. However, the UNIX
On the other side of the client, we will analyze the establishment process of tcpclientsock.Class tcpclientsock: Public basesock {

The answer is: yes. It is about 5-15 kb. I don't know what the default value is. I tested 16371 bytes. Win7 x64.
You can use setsockopt to set the recvbuf or sndbuf size. However, we recommend that you set the number of bytes received each time to a certain range, such as 5 kb. Because even if it is set, it is still possible to accept a small number of bytes.
The more important thing about socket usage is how to process data. InvolvedAlgorithm.
