基于DDNS的移动嵌入式Web服务器的接入方案

摘要

The embedded Web server emerges as the times require with embedded technology and network communication technology highly speed developed.It is an extended application based on the Internet embedded network technology.In this paper,embedded Web technology advantages are firstly analyzed from three aspects,then the role of DDNS technology in embedded Web server is elaborated,following the general embedded module including DDNS module is described,the DDNS working process and message structure are studied,at last,making functional verification of the embedded Web server based on DDNS,which showes that the scheme is feasible,good stability and low cost.And thus,function of embedded Web server is enhanced,it makes key technology analysis of embedded Web server which accessed into Internet with dynamic IP,aimes to establish a set of universal access scheme mobile embedded Web server,so this paper has certain research value.%移动嵌入式Web服务器伴随着嵌入式技术与网络通信技术的高速发展应运而生,是基于Internet的嵌入式技术网络化的扩展应用.先从3个方面对嵌入式Web技术的优点进行了分析,接着阐述了DDNS技术在移动嵌入式Web服务器的重要作用,然后对包含DDNS模块的通用嵌入式模块进行了说明,并对DDNS工作流程及报文结构进行分析,最后对基于移动嵌入式Web服务器的DDNS功能进行了简单验证,实验证明,该方案切实可行,稳定性好且成本低廉.既是对移动嵌入式Web服务器功能的增强,也是对动态IP嵌入式服务器接入Internet的关键技术分析,旨在建立一套移动嵌入式Web服务器的通用接入方案,具有一定的研究价值.
