摘　　要：传统服务器负载均衡的实现方式存在可靠性低、维护性差、增加额外开销等问题.软件定义网络(SDN)在流调度上具有灵活、可靠性高、可维护的特点.在研究现有负载均衡方法的基础上,结合SDN技术,提出基于SDN的云中心动态负载均衡方法,实现了基于流级的动态负载均衡.Floodlight与OVS仿真实验证明,利用SDN技术实现服务器集群负载均衡的方案是可行的.The implementation of load balancing in traditional server has the problems of low reliability,poor maintenance,and additional overhead. The software-defined network（ SDN） is flexible,reliable,and maintainable in terms of flow scheduling. Based on the research of the existing load balancing methods,combined with SDN technology,the SDN-based dynamic load balancing method of cloud center is proposed,and dynamic load balancing based on the flow level is implemented. Floodlight and OVS simulation experiments have proved that it is feasible to implement the load balancing scheme of server cluster by using SDN technology.
