基于网络性能的智能预取技术

Intelligent Prefetch Techniques Based on Network Performance

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.
