【摘要】 针对以往的调度算法对服务器本身的研究较多,而结合网络流量特征采取相应调度策略研究较少的情况.提出了一种结合网络自相似访问特征的接纳控制策略,分析了一种综合考虑Web集群系统中多维调度因子的多目标函数,在此基础上提出了一种既适应网络访问特征,又支持QoS的Web集群调度算法.最后给出了其算法性能测试结果.更多还原

【Abstract】 Many current schedule algorithms researches aim at the web cluster server itself, but few researches aim at combining network traffic character with schedule algorithm, An admission control policy which combines self-similar network traffic character is presented. And a multidimensional object function which integrates multi-schedule factors of web cluster server system is analyzed, based on this policy, a web cluster schedule algorithm which adapts to self-similar network traffic character and support quality of service is proposed. The experimental results are given at the end of the paper.更多还原
