嵌入式Linux系统在中小型网络通信中的设计与实现

The Design and Implementation of the Mini-type Network Communication in the Embedded System Base on Linux

socket(套接字)是网络通信的一种常用方法,它具有编程简单、容易控制、使用方便灵活等特点。文中提出以通过socket编程的方法,实现基于Linux操作系统的嵌入式设备之间,或与互联网用户间的通信,提供了一种在嵌入式设备频繁地自由改变通信地点的情况下,完成网络通信的低成本高效率解决方案。同时介绍了利用GNU的工具开发基于ARM的嵌入式系统,以及使用编译器、连接器和调试工具的具体方法,为广大嵌入式系统开发者提供一种低成本的开发手段。

Socket is a simple and convenient technique for network communication. This paper expounds an approach by means of socket programming to accomplish the communication between Linux based embedded equipments and the Internet users. An economical and highly efficient resolution is provided, and it can resolve the network communication, even if the locations of embedded equipments change frequently. Moreover, this paper introduces the way to develop embedded ARM system by using some GUN tools such as complier, linker and debugger, which is of low cost for many embedded system developers.
