摘要
随着航空航天技术以及卫星互联网技术的快速发展,高速率、高带宽的卫星通信系统逐渐成为下一代移动通信体制的重要组成部分。卫星互联网的发展推进了卫星网络商业化进程,低轨卫星成为构建卫星互联网的重要组成部分。如何实现大规模低轨卫星网络高效可靠的网络管控,完成星地融合组网与路由,逐渐成为了发展卫星互联网的前沿课题。近年来,随着卫星网络规模逐渐扩大,网络管控方法被大量提出。首先,从国内外大规模卫星星座的发展现状出发,调研已有的多种卫星网络的组网架构和协议体系;然后,根据现阶段大规模卫星网络的发展现状,分析对其进行网络管控的难点和关键技术;最后,基于星地融合的组网方式,对现有的解决方案进行调研与分析。
With the rapid advancement of aerospace technology and satellite internet,high-speed and high-bandwidth satellite communication systems have gradually become an essential component of the next-generation mobile communication infrastructure.The trend in the development of satellite internet has propelled the commercialization process of satellite networks,with low earth orbit satellites playing a significant role in constructing satellite internet.The efficient and reliable network management of large-scale low earth orbit satellite networks,along with the integration of space and ground routing,has gradually emerged as a cutting-edge issue in the development of integrated aerospace networks.In recent years,as satellite networks have expanded in scale,numerous network management methods have been proposed.Firstly,begined by examining the development status of large-scale satellite constellations both domestically and internationally,surveying the existing network architecture and protocol systems of various satellite networks.Subsequently,based on the current development status of large-scale satellite networks,the challenges and key technologies involved in satellite management were analyzed.Finally,built upon the network integration of space and ground,existing solutions were extensively researched and analyzed.
