Abstract：Space backbone network is an integrated network composed by the space-air-ground large-scale backbone nodes,and the core of supporting space information network.On the basis of analyzing the sta-tus quo of research on space information network of the Europe and the United States of America,space backbone network architecture and protocol framework are proposed according to the relevant characteris-tics and overall requirements.The network is composed of space-based network,air-based network,and ground-based network.By so doing,this realizes mutual communication and cooperation through inter-sat-ellite links,satellite-air links,satellite-ground links,air-to-air links,air-ground links and terrestrial com-munications lines.The space-based backbone network based on multi-layer satellite network and air-based backbone network based on wireless mesh are mainly studied.Finally,the paper explores the key technolo-gies such as network structure,routing protocols,data transmission technique,heterogeneous compatibil-ity,and network management.This research has some contributions for reference at a certain degree to the construction of future space backbone network.
