[Abstract] Space network, which plays an important role in communications relay, earth observation and navigation, is regarded as the extension of Internet to near space, earth's orbit space and even deep space. In this paper, the typical system architecture of space network is introduced. Moreover, according to the difference of links, dynamic topology and heterogeneous structure characteristics of space network, the key technologies such as protocol architecture, routing, network security and network simulator are pointed out.
