摘　　要：如何有效减少用户访问延时,提高网络服务质量是一个迫切需要解决的难题。缓存与预取技术是克服此难题的有效方法。目前对于预取技术与缓存技术的研究往往强调预取算法或替换策略的改进,缺乏对缓存与预取一体化模型的研究。Web缓存与预取一体化模型IWCPM和仅缓存模型的性能指标相比,Web缓存与预取结合技术比仅缓存技术具有更好的性能表现。How to reduce the user perceived access latency and improve the quality of service of the network is becoming a crucial problem, and Web prefetching and Web caching are the primary solutions. Previous studies in Web caching and prefetching mainly focus on improving replacement policies and building access models and evaluating the performance of such models in predicting future accesses. While these models are important, they lack the consideration of analysis based on integrated Web caching and prefetching system. Integrated Web caching and prefetching model IWCPM is presented and the performance evaluation of IWCPM is made.
