摘要:
为了解决 SDN(软件定义联网)控制平面的扩展性问题,业界提出了逻辑上集中、物理上分布的多 SDN 控制器架构,但是该架构中SDN 控制器和 SDN 交换机之间是静态的映射关系,无法动态适应网络中流量的变化,造成了控制器负载不平衡。为了有效解决多SDN 控制器部署方案中控制器之间负载不平衡的问题,需要实时监控和共享SDN 控制器之间的负载情况,提出一种基于多SDN 控制器的交换机动态迁移机制。该机制在控制器失效或控制器负载过大时能够将SDN 交换机无缝迁移到其他正常的或负载较轻的控制器,避免了控制器单点失效或者负载过大。实施原型系统基Floodlight 控制器。实验结果表明,该方法能够很好地实现控制器之间的负载均衡,减少控制器对 Packet-in 消息的响应时间,提高系统的整体性能。
Abstract:
In order to solve the issue of scalability in SDN (Software Defined Networking) control plane,the multiple SDN-controllers architecture with logical centralization and physical distribution is put forward in the industry. However,it cannot dynamically adapt to the change of traffic in the network and causes a load-imbalance among SDN-controllers due to the statically configured mapping between a SDN-controller and a SDN-switch. In order to solve the problem above,the load is needed to be monitoring and sharing between SDN controllers,and a dynamic migration mechanism based on multiple SDN controllers is proposed which can seamlessly migrate a SDN-switch to a normal SDN-controller or that with less load,avoiding the single point faulure or high load of controller during the event of controller failure or overload. A prototype system based on Floodlight is built. Experimental results show that the proposed method achieves a better load balancing between controllers,reduces the response time of the Packet-in message,and improves the performance of
the whole system.
