卫星互联网组网技术研究

Research on Networking Technology of Satellite Internet

卫星互联网作为第三代互联网技术革命被列入新型基础设施范围,上升为国家战略性工程。鉴于星间组网技术自主安全独特需求,不可复制现有成熟技术。文章围绕卫星互联网星间组网特性,从星间网络、星间链路、星间通信协议和星间路由四个方面系统归纳国内外卫星互联网组网技术,探讨需要突破的组网关键技术、发展方向和解决办法,为卫星互联网组网技术发展提供思路、借鉴与参考。

Satellite internet,as the third generation of internet technology,is included in the scope of the new infrastructure of China,and a spatial information and communication satellite network is also elevated as a national strategic project.In view of the unique requirements of autonomous security of satellite network technology,it is infeasible to copy the mature technologies from other countries.This paper focuses on the key technologies of satellite networking both home and abroad,and then summarizes them in detail in the aspects of satellite network,satellite link,satellite routing and space communication protocol.In order to provide ideas and references for the development of satellite networking technology,the key technologies,directions and solutions in networking are further discussed.
