摘　　要：负载均衡机制是一种用于提高集群整体处理能力的方法,但是不合理的集群结构往往会影响负载均衡机制的效率,两者的不协调在一定程度上限制了系统性能的体现。通过建立负载均衡模拟系统和引入Gini方法,从节点性能分布、节点数量两个角度分析了集群节点结构与其负载均衡机制的相关性,进而提出了一个评测和优化系统能力的方法。最后用实验验证了这个方法的可行性,并给出了进一步的研究方向。Load balancing mechanism is an approach to improve the overall handling capacity of the cluster, but the unreasonable structure of the clusters tends to limit the efficiency of load balancing mechanism. Incoordination between the two limits the performance of system hardware and software. Through establishing the simulation system of load balancing and introducing Gini method, the paper analyzed the relationship between the structure of cluster＇ s nodes and its load balancing mechanism. Then a method was proposed to evaluate and optimize the cluster system. The method was verified by experiment, and direction for further research was pointed out.
