一种基于DHT的Web缓存共享方法

Web caching system based on DHT architecture

提出了一种基于DHT技术的Web缓存共享方法。该方法使得企业网络中所有节点能够相互共享浏览器中的本地缓存,从而形成一个高效的、大规模的分布式缓存共享系统。针对Web缓存共享的系统响应迅速的要求提出一种路由步长为O(2)的路由协议,保证Web查询请求最多只经过一次转发就可到达目标节点。性能分析和仿真实验的结果证明其在路由可靠性、命中率、系统响应和缓存代价方面均有满意的效果。

This paper proposed a Web caching plan based on DHT, whose underlying ideology was that all the terminals in an Intranet were able to share their local caching to constitute a large-scale, effective distributed Web caching system. Given the responding rapidly characteristic of Web caching, proposed a new routing scheme with a constant O （2） hop per lookup request, with which a Web query request could reach the target node within only one transfer. Furthermore, the evaluation results prove that it achieves a satisfied performance in routing reliability, hits-ratio, latency of response and caching cost.
