【摘要】：软件定义网络(SDN)是一种新型的网络架构,其路径是根据全局网络拓扑计算得到的。然而,当前SDN网络中依然存在负载不均衡和不能满足网络流量QoS要求的问题。为此,根据SDN控制器掌握全局网络信息的特点,结合网络感知功能和基于流量的业务划分,利用K最短路径算法,提出一种基于业务划分的路由选择机制。实验结果表明,该机制能够为不同业务类型的数据流选择一条最能满足其QoS要求的路径,并使整个网络达到负载均衡,进而提高了底层网络资源的利用率。
[Abstract]:The software defined network (SDN) is a new network architecture whose path is calculated according to the global network topology. However, the current SDN network still exists the problem of load imbalance and can not meet the network traffic QoS requirements. Therefore, according to the characteristics of global network information grasped by SDN controller, combined with network perception function and traffic partition, a route selection mechanism based on traffic partition is proposed by using K shortest path algorithm. The experimental results show that the mechanism can select a path that can best meet the QoS requirements for different traffic types of data streams, and make the whole network achieve load balance, thus improving the utilization of the underlying network resources.
