摘要
星地融合网络不但可以满足无人自动驾驶、物联网、大连接等新兴服务的需求,而且在灾害预防等公共安全方面也有广泛的应用场景.从星地融合网络如何高效率、低时延地服务地面应用的愿景出发,结合软件定义网络和网络功能虚拟化技术,提出了星地融合智能组网的关键技术,如组网架构、数据感知、接入控制、多维网络切片、时敏性路由转发等,阐述了这些关键技术的原理和性能,探讨了星地融合智能组网现存的挑战和未来发展方向.
The satellite-ground fusion networks can not only meet the demands of emerging services such as auto-driving and large connections,but also be widely used in the disaster alarming and public safety applications.To serve ground applications with high efficiency and low delay for satellite ground fusion network,the key technologies of satellite-ground fusion intelligent networking are proposed.The technologies including networking architecture,data perception,access control,multi-dimensional network slicing,and time-sensitive routing and forwarding are then expounded in terms of principle and performance.Finally,the existing challenges and future directions are discussed.
