基于时延的软件定义航空网络控制器部署策略

Software Defined Aviation Network Controller Deployment Strategy Based on Time-delay

在软件定义航空信息网络架构中,针对控制平面单点失效问题,提出一种多控制器部署方案。通过构建航空集群域,在航空集群域中部署集群控制器,控制器进一步控制该域内飞机来获得网络的高效管理以及信息的有效处理。定义数据传输时延、控制路径时延以及控制器同步时延,以航空信息网络全网时延最小为优化目标,在构建航空集群方面,提出一种k-means改进算法;在集群域中部署控制器时,提出一种时延约束的可靠部署方案。仿真结果表明,该方案能够有效保证全网络的可靠性,并可以有效降低网络中的时延开销,为解决多控制器部署提供了思路。

According to the problem of the failure of single point in the control plane,a multi-controller deployment scheme is proposed in software defined aeronautical information network architecture.The aviation cluster domain is introduced into the article,the cluster controller is deployed in the aviation cluster domain,and the aircraft is controlled by the controller,which have achieved efficient network management and information processing.The data transmission delay,control path delay,and controller synchronization delay are defined,and the minimum delay in the whole network of the aeronautical information network is taken as the optimization target.During the built aviation cluster stage,an improved algorithm based on k-means is proposed,during the determined the position of the controller stage,a reliable deployment scheme with delay constraints is proposed.Simulation results show that the proposed algorithm can ensure the reliability effectively of the whole network,and it can reduce the delay effectively in the network.The scheme provides a way to solve the problem of controller deployment.
