| 摘 要： | 采用集群技术搭建所需的服务器往往导致各服务器系统资源利用率存在很大差距。为解决上述问题，通过分析已有的负载均衡算法，提出一种改进的动态反馈负载均衡算法。调度器定时接收集群中每台服务器上报的性能参数，计算每台服务器当前负载比例值，根据该值计算每台服务器的分发权重，以合理分配用户请求。实验结果证明该算法能有效提高集群系统的整体性能。

| Abstract: | If uses cluster technology to build necessary servers,the utilization rate of every server system resources always has a great distance with each other. In order to solve the problem,this paper proposes an improved dynamic feedback load balance algorithm by analyzing the existing methods. The director receives performance data of every server,calculates the present load proportion of every server,and calculates the distribution proportion to distribute the users' requests reasonably. Experimental result pro... |
