TCP/IP socket programming This is a quick guide/tutorial to learning socket programming in C language on a Linux system. "Linux" because the code snippets shown over here will work only on a Linux system and not on Windows. The windows api to so…

Typically two processes communicate with each other on a single system through one of the following inter process communication techniques. Pipes Message queues Shared memory There are several other methods. But the above are some of the very classic…

对linux中socket的理解 一.socket 一般来说socket有一个别名也叫做套接字. socket起源于Unix,都可以用“打开open –> 读写write/read –> 关闭close”模式来操作.Socket就是该模式的一个实现,socket即是一种特殊的文件,一些socket函数就是对其进行的操作(读/写IO.打开.关闭). 说白了Socket是应用层与TCP/IP协议族通信的中间软件抽象层,它是一组接口.在设计模式中,Socket其实就是一个门面模式,它把复杂的TCP/…

Simple Client-Server socket program in PHP Introduction Sockets are used for interprocess communication. Interprocess communication is generally based on client-server model. In this case, client-server are the applications that interact with each ot…

Conclusion And that's all there is to it! Here is how our client looks like Here is how our server looks like That is all there is to the socket programming.…

Getting Started You can argue that one can overcome these shortcomings by multithreading meaning that one can spawn a new thread and let that thread do the polling which then notifies the main thread of the data. This concept could work well, but eve…

This is the second part of the previous article about the socket programming. In the earlier article we created a client but that client used to make blocking IO calls ( Receive ) to read data at regular intervals (via clicking the Rx button). But as…

开发测试环境:虚拟机CentOS,windows网络调试助手        非阻塞模式有3种用途        1.三次握手同时做其他的处理.connect要花一个往返时间完成,从几毫秒的局域网到几百毫秒或几秒的广域网.这段时间可能有一些其他的处理要执行,比如数据准备,预处理等.        2.用这种技术建立多个连接.这在web浏览器中很普遍.        3.由于程序用select等待连接完成,可以设置一个select等待时间限制,从而缩短connect超时时间.多数实现中,connec…

Linux内核socket优化项 vi /etc/sysctl.confnet.core.netdev_max_backlog = 30000  每个网络接口接收数据包的速率比内核处理这些包的速率快时,允许送到队列的数据包的最大数目 net.core.somaxconn = 262144   用来限制监听(LISTEN)队列最大数据包的数量,超过这个数量就会导致链接超时或者触发重传机制 net.core.rmem_default = 8388608    接收套接字缓冲区大小的默认值(以字节为单…
