| 摘 要： | Web缓存技术是提高Web性能的一种有效方法,缓存管理是Web缓存技术的核心,研究Web访问特征的数学模型是有效进行Web缓存管理的基础。本文根据Web缓存流量访问特征建立数学模型,设计实现了Web缓存流量特征模拟生成器(WebTraffsim),利用两层代理缓存结构,对Web缓存流量的访问特征和性能进行测试,对Web缓存替换算法(LRU,LFU,LRV)进行了性能评价和分析。

| Abstract: | Web caching technology is an effective approach to improving Web performance. The management of Web caching is the key issue of Web caching technology,and the study of mathematical model of Web reference characteristics is the basis of effective management of Web caching. A synthetic Web workload generator(WebTraffsim) was designed and implemented based on the mathematic model established by Web characteristics in this paper. The simulated experiments made use of two-level proxy caching to evaluate the refe... |
