文章摘要
软件定义网络(SDN)是一种新型网络架构。在SDN架构中控制层能够从数据层获得网络的吞吐量、连通性和流量的全局视图,并且能够细粒度地对流量进行控制。链路分离多路径算法在生存网络、QoS感知通信网络和SDN控制网络中有很重要的研究价值。针对SDN环境下网络的可靠性和负载均衡优化问题,改进Dijkstra算法并且与分离路径算法相结合,实现SDN下对流量的灵活控制。在SDN环境下对链路分离路径算法进行仿真验证,证明路径分离算法的有效性。实验结果表明,算法既均衡了路径之间的负载,又提高了网络的可靠性。
Abstract
Software Defined Network(SDN) is a new type of network architecture. In the SDN architecture, the control layer can obtain the global view of network throughput, connectivity, and traffic from the data layer. And the control layer can also control the traffic in a fine-grained manner. The link disjointed multi-path algorithm has important research value in the survival network, QoS-aware communication network and SDN control network. For the reliability and load balancing optimization of the network in the SDN environment, Dijkstra was improved and combined with the separation path algorithm to achieve flexible control of traffic under the SDN. In the SDN environment, the link disjointed path algorithm was simulated and verified. It proves the effectiveness of the path separation algorithm. Experimental results show that the algorithm can not only balance the load between the paths, but also improves the reliability of the network.
