基于Internet的高速缓存技术分析

Analysis of caching technology based on Internet

Internet的迅速发展 ,使网上的数据量惊人地增加 ,造成网络带宽严重不足。高速缓存是一种对频繁访问 Web信息的请求在本地实现的技术 ,它能降低 Internet的信息流量、提高用户的访问速率。文章在研究了高速缓存工作原理的基础上 ,综合分析了基于 Internet的缓存技术的 3种实现方案 :基于浏览器的客户机缓存、代理服务器和网络缓存 ,分析了它们各自的工作特点和应用场合 ,并展望了缓存技术的应用前景。

The uncontrolled growth of Internet makes the volume of Web content staggering and the bandwidth inadequate. Caching is the technique of keeping frequently accessed information in a location close to the request,and it can reduce the volume of Web traffic on Internet and improve the speed for end users' access to Web pages. In this paper,the caching principles are studied, the three caching solutions based on Internet are analyzed comprehensively: browser-based client caching,proxy servers and network cache. The features and use occasion of the three solutions are discussed, and the application prospect of Internet caching is also shown.
