摘　　要：通过对WEB应用负荷与现有WEB服务器体系结构不相适应的问题分析和研究,提出了基于业务载荷的自适应动态资源调度.首先从互联网24小时载荷变化分析现有WEB服务系统能效比较低的原因,然后介绍了基于认知的主动重构WEB服务以及动态资源调度所需参数及感知方法,并基于此提出了负荷预测和自适应动态资源调度算法,最后通过实验验证了算法的有效性.Through analysis of the problem that WEB application loads are incompatible with the existing architecture of WEB server,we propose a load adaptive dynamic resource scheduling.Firstly,analyze the reason of low energy efficiency ratio for existing WEB service system through the load changes from the Internet 24 hours,and then introduced WEB services oriented reconfigurable architecture with proactive perception and parameters/sensing methods required by dynamic resource scheduling for WEB services,and based on this proposed load prediction and adaptive dynamic resource scheduling algorithm,and finally prove the algorithm is effective through experiments.

关 键 词：自适应 动态资源调度 主动重构 WEB服务
