Abstract: For the design of Space Information Networks (SINs) architecture and the multiplicity and multidimension problems of its mission task, a reconfigurable design method of SINs architecture was proposed. Firstly, the development of SINs and its architecture at home and abroad were introduced, and the requirement of reorganization design of SINs architecture was analyzed. Secondly, based on the concept, structure and characteristics of SINs, some reorganization design principles including loose coupling, compatibility, isolation and deconstruction were established. Meanwhile, the connotations of the Reorganization Management Center (RMC) and the Reorganization Resource Center (RRC) were defined, and the operating mechanism of RMC and RRC was analyzed. A formalized reorganization network architecture model based on 5 dimensions of target, topology, entity, data and scheme was proposed, and the realization algorithm flow of reorganization network architecture was given. Finally,a case study of the architecture reorganization design with an example of an antimissile operation was carried out, and a simulation demonstration of reorganization network on the STK platform was realized. The application of reorganization design in practice was demonstrated and verified, achieving the desired goal.

Key words: space information networks, architecture, resources reorganization, data as a center, task traction
