针对传统互联网调度无法满足工业业务QoS(Quality of Service)需求的问题,文中在基于SDN的新型网络架构上提出了一种改进的路由算法,并对其中使用的Floodlight控制器模块进行扩展与修改.根据信息收集单元模块提供的带宽信息与链路发现模块提供的网络拓扑信息,路由计算模块对进入的数据流计算出更优化的最短路径.仿真实验结果表明,改进后的路由算法有效降低了数据的传输时延,增强了网络的稳定性.
Research on an improved routing algorithm based on SDN
To solve the problem that traditional Internet scheduling can not meet the requirements of indus-trial service QoS(Quality of Service),this paper proposes an improved routing algorithm on the new net-work architecture based on SDN,and expands and modifies the floodlight controller module used in it.Ac-cording to the bandwidth information provided by the information collection unit module and the network to-pology information provided by the link discovery module,the routing calculation module calculates a more optimized shortest path for the incoming data flow.Simulation results show that the improved routing algo-rithm effectively reduces the data transmission delay and enhances the stability of the network.
