摘要:
 目前,OpenFlow网络还没有一套完整的负载均衡解决方案,使得整体网络资源利用率不高。文中利用OpenFlow网络控制器集中控制的优势,在控制器上设计并实现了一种动态负载均衡路由策略。该策略能够根据网络状态信息动态制定数据流转发策略：以链路多指标综合评价值作为链路新的权重,并以此新权重计算源节点与目的节点间的最优路径,从而引导数据流时刻处于最优转发路径上。最后利用Mininet仿真技术,对文中提出的负载均衡路由策略进行性能验证仿真实验。结果表明,文中提出的负载均衡路由策略有效缓解了网络拥塞,提高了链路利用率。
Abstract:
 The underutilization of network resources is low, which resulted from the absence of a complete load-balancing solution in OpenFlow network. In this paper,a dynamic load balancing routing strategy for data flows is proposed and implemented on the controller of OpenFlow network,utilizing the centralized controlling advantages of controllers in OpenFlow network. The strategy could develop a dynamic data flows forwarding policy based on network condition information:the multi-index comprehensive evaluations of links served as the new weights which are applied in calculations of the best path between the source node and the destination node;sequentially the data flows would be forwarded on the best path at all times. At last,the Mininet simulation technology is used in verifying the perform-ance of the proposed load-balancing routing strategy in this paper. The results show that the proposed load-balancing routing strategy can effectively alleviate the congestion of networks and improve the utilization of links.
