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.
負載均衡機製是一種用于提高集群整體處理能力的方法,但是不閤理的集群結構往往會影響負載均衡機製的效率,兩者的不協調在一定程度上限製瞭繫統性能的體現.通過建立負載均衡模擬繫統和引入Gini方法,從節點性能分佈、節點數量兩箇角度分析瞭集群節點結構與其負載均衡機製的相關性,進而提齣瞭一箇評測和優化繫統能力的方法.最後用實驗驗證瞭這箇方法的可行性,併給齣瞭進一步的研究方嚮.

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.
