摘要
为了提高基于SDN技术的电力业务传输可靠性,研究了在SDN分布式多控制器部署方案中的高可靠性业务支撑机制。针对控制器与交换机间通信的可靠性参数,研究了基于聚类的控制器放置算法、基于贪婪的控制器放置算法和随机控制器放置算法,对比了3种控制器放置算法的优劣。经过验证,并基于特定电力应用场景,得出在SDN网络中,基于聚类的控制器放置算法可以保障电网的可靠运行。
In order to improve the power transmission reliability based on SDN technology, this paper proposes a high reliability business support system in SDN distributed multi controller deployment. According to reliability parameters of the controller and inter-switch communication, this paper presents the clustering placement algorithm, the random placement algorithm and the greedy placement algorithm. Then this paper gives a comparison of these controller placement algorithms and a verifi cation in special application scenarios, the results show that clustering placement algorithm of controller can improve the reliability of power service transmission in SDN networks.
