| 摘 要： | 利用集群技术构建的服务器组在资源利用率上存在较大差异。为此，提出基于层次分析法(AHP)的集群系统负载均衡算法，建立判断矩阵，得到各项评估指标的单项和综合权重。调度器定时接收真实服务器上的4类参数：网络性能，服务器硬件，服务器软件和网络服务类型。根据调度器收到的每一个连接请求，采用动态反馈算法选择负载最小的服务器响应连接请求。实验结果表明，该算法能减少服务器平均响应时间，有效提高集群系统的响应率。

| Abstract: | If uses cluster technology to build servers,the utilization rate of every server system resources has a great distance with each other.In order to solve the problem,this paper proposes a load balancing model based on Analytic Hierarchy Process（AHP） of Web-Server Cluster System,establishes comparison matrix,obtains individual and overall weight of every evaluation items.The scheduler receives four major categories performance parameters-network performance,server hardware,server software and network service type.Scheduler for each connection requests calculate the minimum load server by the dynamic feedback algorithm to respond to connection requests.Experimental results show that this method can reduce the average server response time,and improve the response rate of cluster system. |
