天地一体化信息网络天基宽带骨干互联系统初步考虑

[摘要] 认为天基宽带骨干互联系统是天地一体化信息网络（ISTIN）的核心。在分析全球典型系统架构的基础上，结合中国国情提出了一种新的天基宽带骨干互联系统网络架构——天地双骨干。同时，综合考虑天地链路信道特征和星上处理能力约束，提出了激光/微波混合传输、电路和分组混合交换等技术体制，为系统建设提供参考。

[Abstract] The space wideband backbone interconnected system is the core of the integrated space and terrestrial information network (ISTIN). In this paper, we compare the major network architectures in the world, and propose a novel space and terrestrial dual backbone architecture for the space wideband backbone interconnected system based on the condition of our country. Furthermore, considering of the space-terrestrial link character and on board processing ability, we propose the scheme of laser/ radio frequency (RF) hybrid transmission and circuit/packet hybrid switching for the system construction.
