面向瘦客户端的WebOS研究

Research on Thin-client Oriented Web Operating Systems

基于浏览器的WebOS是操作系统技术向网络化发展的一个典型代表。WebOS整合Internet上服务和资源,供在线用户"随时随地"使用,这种特点使得它将成为未来瘦客户端Web应用的一种重要使用模式。首先阐述了WebOS的由来、概念和组成,接着分析了WebOS的发展现状和趋势,然后论述了制约其发展的主要技术因素。在此基础上,选择较有代表性的开源EyeOS进行了深入研究,分析了其原理和组成,并对其服务器端功能进行了扩充。

With the development of distributed computing technologies, browser-based Web operating system （WebOS） came into being. It provides mechanisms for integrating services and resources on the Internet. And it makes services and resources available for online users regardless of where they are and when it is. WebOS represents a trend towards future use of thin client based Web applications. It has become one of the most important patterns of utilization in the coming cloud computing era. We first introduced the concepts and structure of WebOS. Then we analyzed related work and the trends of WebOS. And we also discussed the technical factors which cumber the development of WebOS. Finally, we made comprehensive research on EyeOS, which is a typical open source WebOS. We analyzed EyeOS＇s structure and APIs. Then we extended its functions by implement a SOAP-based Travel service.
