基于SDN的多路径并行传输数据调度方法

摘要

For because of path difference and there is no guarantee that the receiver does not produce the problem such as out-of-order data, puts forward a data transmission scheduling method based on the technology of SDN. The method of path through path condition monitoring module cache occupancy for real-time monitoring, at the same time, the advantages of using the tech-nique of SDN control flexibility, according to the ratio of the cache occupies and path flow balanced scheduling was carried out on the transmission of data. Experimental results show that the method can be used to make the data transmission path load av-erage, achieve the goal of path optimization.%针对因路径差异而无法保证接收端不产生数据乱序等问题，提出了一种基于SDN技术的传输数据调度方法。该方法通过路径状态监测模块对路径的缓存占用比进行实时监测，同时利用了SDN 技术的操控灵活性等优点，根据缓存所占用的比率以及路径流量对传输的数据进行均衡的调度。实验表明，利用该方法可使传输数据的路径负载平均，达到路径最优化的目的。
