摘　　要：利用SDN的技术优势,可建立航空信息网络平台集中管控与资源统一调度的能力,显著提升网络管理能力与任务服务水平。为构建SDN范式的航空信息网络,首先需要解决控制节点的部署问题。结合航空场景特点,提出一种网络划分与区域部署的控制器部署方法,首先依据网络关键性能指标实现网络的快速划分,接下来基于可靠性最大化在网络中部署控制器。仿真结果表明:所提算法具有较低的计算复杂度,并对平均请求时延、负载均衡指数、网络部署成本及可靠性等指标具有较好的优化性能,适用于解决航空场景下的控制器部署问题。Software defined network(SDN)being enabled to decouple the control plane and the data plane by adopting a logically centralized approach to realize the network management,andutilizing the advantages of SDN,it is possible to build the ability of the centralized platforms controlling and unified network resources scheduling.To construct an aviation information network(AIN)of the SDN paradigm,the controller placement is put in the first place.In combination with the characteristics of aviation scenarios,this paper proposes a controller deployment strategy including network division and regional deployment.Firstly,the network is rapidly divided according to the key performance indicators of the network,and then the controller is deployed on the platform with the maximum reliability.The experimental result shows that the proposed algorithm has low computational complexity,and can effectively improve the network performance in terms of average requirement delay,load balance index,controller deployment cost and reliability,and is suitable for addressing the controller deployment issue in AIN scenario.
