摘要
本文论述了基于 RTT(Round TriP Time)等网络性能指标的 Web智能预取技术,在对 Web代理服务器上的业务进行分析和对网络RTT进行测量分析的基础上,提出了新的Cache替换方法及预取控制技术。对新算法的仿真表明,该方法提高了缓存的命中率,在不明显增加网络负荷的前提下,提高了业务的响应速度。
This paper describes the intelligent prefetch techniques. Based on analyzing the proxy traffic and measurement of network RTT we propose a new algorithm for cache replacement and a new method to control the prefecthing. The simulation results show that our cache replacement algorithm has a higher hit rate and our control method decreases the wait time of web access requests.
