摘　　要：从设置服务器集群的策略出发,通过将多个高级服务器的主机连成群集,对每个节点服务器引入节点权重和节点负载量,对于每一周期的任务进行节点剩余负载量分析,动态反馈调节任务分配,以保证将新到达的任务分配到负载最轻的服务器。既考虑了服务器的处理能力,同时也兼顾了当前负载,提高了集群系统的整体性能。This article embarks from the strategy of server cluster＇s establishment ,through connecting many a high-quality server to a mainframe cluster, each node server introducing weights and the capacity, analyzing the node surplus capacity regarding each cycle＇s duty, controlling task allocation by dynamic feedback to ensure that the new arrivals will be assigned to the lightest load server. While considering the handling capacity of the server, but also taking into account the current load, the overall performance of cluster system is improved.

关 键 词：集群 负载均衡 动态反馈 权重
