Biography: Liu Lixiang, born in June 1973 in Anqing, Anhui Province. He is a professor and doctoral supervisor of the Institute of software of the Chinese Academy of Sciences(ISCAS). He graduated from the school of electronic engineering of Shanghai Jiaotong University in 2002 with a doctor's degree. In 2003, he entered the post-doctoral research station of computer science and technology of ISCAS, and from 2005 he worked in ISCAS. He is the member of the expert group of High-resolution Earth Observation System, the space-earth integration network of the Ministry of science and technology, and the public safety demonstration of the Chinese Academy of Sciences. His research Interests: intelligent networking of space-based integrated information systems, ground verification of large-scale network integrated system and complex information system architecture. He has successively took charge of more than 40 projects of 863, 973, Chinese Academy of Sciences and natural science fund, achieved a number of research results. Won 863 advanced individuals, advanced project team, second prize of national science and Technology Progress Award etc. He has published more than 70 papers and more than 10 patents in important academic journals and conferences,and published a monograph on the integration of space and earth network. He has developed a set of "satellite networking protocol stack", "satellite network test bed" and "Satellite Internet architecture analysis platform" with independent intellectual property rights, which have been applied in the "Xingyun" project, "Hongyun" project, the national "Space-Earth integrated network" and the national "satellite network" project.

Title: Space-ground Integrated Network Networking Architecture and Technologies

Abstract: As the core infrastructure of information acquisition, distribution, transmission and application in the future, space-ground integrated network( SGIN) will play a very important role in the development of national economy and society. Network and protocol architecture face great challenges because of operation environment and the diversity application of SGIN. On the basis of the characteristics of SGIN, a new architecture of distributed edge computing+space-based station integrated network architecture is proposed based on service network. The core problems need to be solved are analyzed, and the protocol architecture and ground simulation test bed are realized.
