通过对加权最小连接数算法的进一步改进，实现服务器负载均衡。针对该算法的改进做了周期性的权值信息收集，并对中途产生用户高峰而引起服务器过载问题进行有效解决，按照类别的不同进行统一分配任务的研究。通过对服务器资源的有效收集，进行逐一服务器权值计算和资源分类，并建立相应的数学模型等。应用CloudSim进行仿真实验，结果表明改进后的加权最小连接数调度算法具有更好的均衡性和可靠性，能更好的解决负载不均衡问题。

To achieve the purpose of the server load balance the weighted least connections algorithm was improved.The improvement of this algorithm contained two aspects.On the one hand, periodic weighting information was collected, and on the other hand, the overload problem of server visited by too many customers was solved by unified allocation of tasks in accordance with the different categories.Through the effective collection of server resources, weight calculation and resources classification can be received respectively, and at the same time the corresponding mathematical model can be established.In addition, the CloudSim simulation experiment was performed, and the results showed that least weighted connections algorithm had better balance and reliability which can better solve the load imbalance prob-lem.
