基于SDN的天地一体化网络控制器部署方法综述

Review of Controller Deployment Methods for Space-ground Integrated Network Based on SDN

软件定义网络(SDN,software define network)推动了传统网络的发展,将SDN引入天地一体化网络能够极大程度地调动各层级网络的资源,实现天地一体化网络的智能管控;首先,介绍了天地一体化网络和软件定义网络,论述了基于SDN的天地一体化网络架构的研究现状;随后,介绍了SDN控制器的性能指标并对比了当前的SDN多控制器部署方法,综述了基于SDN的天地一体化网络的控制器部署策略;最后,对未来基于SDN的天地一体化网络控制器部署方法进行了展望和归纳总结。

Software-defined network(SDN)promotes the development of traditional network.The introduction of the SDN into the space-ground integrated network can greatly mobilize the resources of networks at all levels.At the same time,the intelligent management and control of the space-ground integrated network are realized.Firstly,the space-ground integrated network and software-defined network are introduced,and the research status of the space-ground integrated network architecture based on the SDN is discussed.Then,the performance index of the SDN controller is introduced,compared with the current SDN multi-controller deployment method,the controller deployment strategy of the SDN based on the space-ground integrated network is summarized.Finally,the future deployment method of the SDN based on the space-ground integrated network controller is prospected and summarized.
