Abstract:

Survivable routing technology is one of the key technologies to ensure the longterm stable operation of space information networks. Using the pathological self-healing mechanism with the body for reference, a set of ideas and methods are presented to explore the space information network survivability routing technology. The self-healing mechanism of space-based information network routing failure is concluded through combing a research of modern pathology and analysis of body tissue disease self-conditioning mechanism. And then, the operational characteristics of network structure, routing process, routing and fault factors and the causes of space-based information networks are analyzed, the self-healing routing failures control strategies and models of space-based information networks are constructed, routing fault active control technologies, which includes clustering, link repair, incremental correction, are designed. Finally, a survivable routing algorithm of spacebased information networks routing failures is designed, and the space-based information network self-healing routing fault simulation frame and environment are developed to evaluate the network structure, routing fault self-recovery mechanism and the survivable routing.
