Awareness of Space Information Network and Its Future Architecture

Abstract

Entering to the 21st century, with the rapid development of information technology and the increasing expansion of mankind activity, The space information network (SIN) has become the key development field in the great powers around the world, the study of SIN shows an ascendant trend. Based on the analysis of the dynamic and developing trend of SIN at home and abroad, by studying the characteristics of SIN and its essential rules, and in the face of two kinds of developing tendency such as “Resilient and Decentralized Spatial Architecture” and “Integrated and Large-scale Spatial Architecture”, this thesis proposes a new SIN architecture called “Space Information Cloud (SIC)”, and has deeply studied the system structure of the public cloud in the space information cloud (SIC). In the end, the key technologies relevant to the space broadband backbone network were analyzed and discussed oriented to SIC. So as to provide reference about the development of SIN in China.
