摘　　要：针对广域网SDN化面临的控制平面路由计算负载大、网络抗毁性低等问题,分析传统集群方式控制架构难以适用广域网应用场景的原因,提出一种适用于广域网的SDN分级分域控制平面组网架构。研究了此架构下的控制器任务分工与路由计算方法,并提出一种抗毁组网方法。经实验验证表明,该方法可以实现在控制器失联情况下数据互通,保证分级分域SDN控制器组网架构在广域网应用的抗毁性。The software defined wide area networking control plane has such problems as large routing calculation load,low survivability,etc.Aiming at these problems,this paper analyzes the reason that the typical clustered control structure is difficult to apply to SDN.The controller task assignment and route computing method under this architecture is studied,and a survivability networking method is proposed.The experiment results show that this method can implement data communication when the controller is in failure to ensure high-survivability application of SDN controller networking architecture in wide area network（WAN）.
