摘要 Web预取技术是减少网络延迟,提高服务质量的主要解决方案之一.利用Zipf第一定律和Zipf第二定律建立Web对象访问流行度模型.对于访问频率较高的Web对象,利用Zipf第一定律建模;而对于访问频率较低的Web对象,则使用Zipf第二定律进行描述. Web prefetching technique is one of the primary solutions used to improve the QOS. This paper makes use of Zipf's 1st law and Zipf's 2nd law, respectively to model the web object's popularity. For frequently visited Web objects, Zipf's first law was used to model; for less frequently visited objects, the Zipf's 2nd law was employed to describe.
