摘　　要：巨型星座中海量网元对现有网络架构和技术体制提出了严峻挑战,如何设计和规划网络体系架构是巨型星座发展的关键问题之一。从星座架构的概念与特征出发,结合国内外卫星星座发展情况与技术预判,提出“四面”(感知平面、数据平面、控制平面、智能管理平面)和“三层”(资源层、传送层、业务层)的多层多域混合式智能协同组网体系架构,设计星座网络管控架构、技术参考模型与协议架构等。同时,针对星座建设与发展趋势,阐述并分析星座网络编址路由、网络鲁棒性敏捷保障、差异化业务承载、端到端可靠传送等关键技术的演化趋势,支撑我国低轨巨型星座网络发展与建设。The large number of network elements in the mega-constellations pose a severe challenge to the existing network architecture and technical system.Based on the concept and characteristics of constellation architecture,combined with the development of domestic and foreign satellite constellations and technology prediction,a multi-layer and multi-domain hybrid intelligent cooperative network architecture was proposed,which consist of four layers(perception plane,data plane,control plane,intelligent management plane)and three layers(resource layer,transport layer,service layer),the architecture of constellation network management and control,technolo-gy reference model and protocol architecture were designed.At the same time,accorded to the construction and development trend of constellation,this paper expounded and analyzed the evolution trend of the key technologies,such as constellation network addressing and routing,network robust agile guarantee,differentiated service bearing,end-to-end reliable transmission,etc.The research results could support the development and construction of LEO giant constellation network in our country.
