摘　　要：针对软件定义网络中数据传输的低延迟和实时性要求,提出一种基于模糊理论的数据流选择及实时路由更新策略.首先基于模糊理论和链路可用容量确定需要更新的数据流,然后根据链路容量和交换机存储容量的限制进一步挖掘可以同步更新的数据流,以实现实时路由更新.仿真实验结果表明,所提方法能在大大降低路由更新延迟的同时较好地满足负载均衡.Aiming at the requirements of low delay and real-time data transmission in software defined networking,a data flow selection and real-time route update strategy based on fuzzy theory is presented.Firstly,the data flows to be updated are determined by using the fuzzy theory and link available capacity,and then the data flows to be updated synchronously are investigated according to the limitations of link capacity and switch storage capacity,so as to achieve real-time route updates.The simulation experimental results show that the presented strategy can achieve load balancing while greatly reducing the route update delay.
