摘要:

利用最短路径法控制准则进行控制网络可靠性设计时,容易选择出高故障率链路,导致控制网络不可靠。为此,以链路可靠性指标为控制准则,提出一种提升控制网络可靠性的方案。运用控制器位置部署算法在网络中选择合理位置进行控制器部署,使控制器以最可靠链路到达 OpenFlow交换机。仿真结果表明,在可靠性指数方面,该方案对常用控制网络管理方式的改进最高可达85%。

Abstract:

When using the shortest path control rule to design reliability of control network,it is easy to choose high failure rate link,resulting in unreliable control network.Therefore,taking link reliability index as a control rule,a scheme of improving the reliability of control network is proposed.By using the controller location deployment algorithm,we choose a reasonable location in the network to deploy the controller,and the controller reaches the OpenFlow switch with the most reliable link.Simulation results show that,in terms of reliability index,the scheme improves the management mode of commonly used control network up to 85%.

Key words: Software Defined Networking(SDN), reliability, OpenFlow switch, shortest path method, control rule
