本文将从一个初学者的角度开始聊起，让大家了解 Socket 是什么以及它的原理和内核实现。 一、Socket 的概念 Socket 就如同我们日常生活中的插头与插座的连接关系。在网络编程中，Socket 是一种实现网络通信的接口或机制。 想象一下，插头插入插座后，电流得以 ...

笔者一直觉得如果能知道从应用到框架再到操作系统的每一处代码，是一件Exciting的事情。今天笔者就来从Linux源码的角度看下Server端的Socket在进行bind的时候到底做了哪些事情(基于Linux 3.10内核)。 一个最简单的Server端例子 众所周知，一个Server端Socket的建立，需要 ...

Sockets provide an interface into the kernel’s networking protocols by allowing programmers to create a communication endpoint in the form of a file descriptor, and by binding a name to the file ...
