Abstract

The explosive growth of network data traffic puts new demands on traffic scheduling. In this paper, the scheduling algorithm based on the software-defined network (SDN) architecture is studied. Firstly, the SDN architecture was introduced, then an SDN-based adaptive multi-path load balancing algorithm was proposed and finally the algorithm was simulated on the Mininet simulation platform to compare the performance of the proposed algorithm and traditional equal-cost multi-path routing algorithm by using Ryu as the controller. It was found that the proposed algorithm had greater throughput, higher bandwidth utilization and shorter transmission time in allocation scheduling of network data traffic, which could effectively reduce network congestion and ensure the reliability of the network. This study verifies the effectiveness of the proposed method in allocation scheduling of network data traffic and provides some theoretical bases for the further application of the SDN architecture-based allocation scheduling algorithm.

基于SDN架构的网络数据流量多径分配调度优化算法

摘要

网络数据流量的爆炸性增长对流量调度提出了新的要求。本文研究了基于软件定义网络（SDN）架构的调度算法。首先介绍了SDN架构，然后提出了一种基于SDN的自适应多路径负载均衡算法，最后在Mininet仿真平台上对该算法进行了仿真，比较了该算法与传统等价多路径路由的性能。 Ryu作为控制器的算法。结果表明，该算法在网络数据流量的分配调度中具有更高的吞吐量，更高的带宽利用率和更短的传输时间，可以有效减少网络拥塞，保证网络的可靠性。
