摘要 设计良好的Web缓存替换策略能使网络上的资源得到最有效的利用。文章设计了一个较有效率的Web缓存替换策略LFRU,期望以较佳的方式获得网络资源及改善Web缓存的性能和服务质量。实验结果表明该策略有较高的文档命中率和字节命中率。 When the requested objects cannot be found in the Web cache and Web cache is full, the removed objects are determined by the efficient cache replacement policy to achieve fewer removals and higher cache utilization. This paper proposes a new and efficient cache replacement policy to improve the processing performance and enhance the quality of service (QoS) on the Web servers. The results of experimentation show that this formula can achieve both document hit rate and document byte hit rate.
