摘　　要：提出了一种基于 peer to peer技术的分布式Web缓存共享系统:BuddyWeb.该系统的核心理念是让企业网络中的所有PC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,并使系统具备易管理、易实现、低成本等优点;接着详细阐述了 BuddyWeb的工作原理和算法策略;然后,针对 Buddy Web系统的特性提出了仿真实验模型和评估方法.实验结果证明了BuddyWeb在命中率、网络通信流量负荷、系统响应延迟等诸方面均能取得令人满意的效果.In this paper, a collaborative P2P based Web caching system, named BuddyWeb, has been proposed, whose underlying ideology is that all the PCs in an Intranet are able to share their local caching to constitute a large scale, effective collaborative Web caching system. BuddyWeb distinguishes itself from others with the advantages of scalability, effectiveness and low cost. Furthermore, the working mechanism and the algorithm of the system have also been detailed. In addition, a simulation model has been devised to evaluate such a system. And the evaluation results show BuddyWeb achieves a satisfied performance in hits ratio, traffic load and latency of response.
