摘　　要：为解决数据中心出现网络链路拥塞,形成瓶颈链路的问题,进行基于OpenFlow网络的服务器负载均衡策略的研究,改善网络资源利用率,从而使服务器在现有宽带资源条件下达到更高的服务质量。文中先设计了OpenFlow控制器的整体模块以及服务器管理节点模块,然后从虚拟机迁移出发,结合应用要求以及现代数据中心网络的特征等对负载均衡策略进行设计,并采取了实验检验该对策的有用性。实验结果表明,组播服务有效减小了负载,降低了实现难度,具有一定应用价值。In order to solve the problem of network link congestion in the data center and the formation of bottleneck links,the research on the server load balancing strategy based on OpenFlow network is carried out to improve the utilization of network resources,so that the server can provide higher quality of service under the existing broadband resource conditions.This paper first designs the overall module of the OpenFlow controller and the server management node module,and then starts from the virtual machine migration,combines the application requirements and the characteristics of the modern data center network to design the load balancing strategy,and takes experiments to test the usefulness of the strategy.The experiment results show that the multicast service effectively reduces the load,reduces the difficulty of implementation,and has certain application value.
