摘要
星地融合组网是未来网络的发展趋势,但是卫星星座拓扑的高动态变化,端到端的业务传输仍存在挑战。软件定义网络作为解决网络动态管理的重要技术,近些年来被应用于星地网络中。介绍了现有的软件定义网络的星地组网体系架构,研究了控制器部署位置对组网体系架构的影响。此外,分析了软件定义星地组网架构的应用前景。
The integrated satellite and terrestrial network is the development trend of future networks.Since the highly dynamic changes in the satellite constellation topology,there exist challenges in end-to-end service transmission.As an important technology for solving network dynamic management,software-defined networking has been applied to integrated satellite and terrestrial network in recent years.The existing integrated satellite and terrestrial network architectures based on software-defined networking are introduced,in which the deployment strategies of the controllers are studied.In addition,the application prospects of the software-defined integrated satellite and terrestrial network are analyzed.
