摘要
传统网络在负载均衡方面存在技术劣势,文章将蜜蜂进化型算法(BEGA)应用在基于软件定义网络(SDN)架构,实现数据传输路径负载均衡。在SDN控制器中BEGA通过计算网络链路的负载状态,选择较小的链路负载,同时将状态数据流表下发到SDN交换机完成数据传输。选用胖树拓扑在Mininet平台上进行仿真实验,实验结果表明BEGA可提高数据中心网络的吞吐量和平均链路利用率。
Traditional networks have technical disadvantages in load balancing.In this paper,Bee Evolutionary Algorithm(BEGA)is applied to SDN network architecture to realize data transmission path load balancing.In the SDN controller,BEGA calculates the load state of the network link,selects the smaller link load,and sends the state data flow table to the SDN switch to complete the data transmission.The simulation experiment is carried out on Mininet platform with fat tree topology.The experimental results show that BEGA can improve the throughput and average link utilization of data center network.
