| Abstract: | Analyzed and discussed in this paper are two survivable system models based on information redundant partition technology-high reliability model and high security model. Firstly, the bipartite graph model is built for information redundant partition systems. Then based on the relationship between node cover set and system survivability in graphic model G=(S,Z;E) , an effective way of analyzing the system survivability is presented. Finally, detailed analysis of the high reliability model and high security model is given, which includes the system survivability characteristics, the limitations and methods of improvement for the models. The analysis results show the effectiveness of the system survivability improvement by rational information redundant partition technology. |
