中文摘要：
树型加速器中缓存间的共享对于减少Web流量、减轻网络拥塞和改善用户访问时间是一项关键技术,已成为研究热点.基于文件缓存生存期的思想,提出并实现了树型加速器中的EA文件分布算法,改进了[5]中存在的缺陷,定量分析了EA模式和传统模式.在树型加速器中基于两种模式进行了试验和结果分析,实验证明,EA模式在累积命中率、累积字节命中率和平均延迟方面要好于现有的传统模式.
英文摘要：
As a key technology to reduce the Web traffic, allivate network traffic and inprove user＇s access time,the share among caches in the tree-base accelerator becomes a heated research issue. Based on the theory of cache expiration age of file, this paper proposes and realizes EA document placement algorithms in the tree-base accelerator,improves the shortcomings in^[5] and analyzes EA model and tranditional model quantitively, the experiments and analysis in the tree-base accelerator based on two models show that EA model is superior to the tranditional model in cumulate hit rate ,cumulate hit rate of byte and average delay.
