Paper Abstract:	In conventional network science, we have considered the network as a single graph so that analyzed its characteristics. As a result, “scale-free” and “small-world” were discovered. However, it can be thought that the network exists not as a single, but as it is related to each other. The relationship between the networks makes a phenomenon that can’t be explained by looking at a single network. A representative example of this phenomenon is the massive blackout that occurred in Italy in 2003. This is the incident that was caused by the mutual dependence between the electricity grid and the control network forming the electric power network. When constructing a network, it is common to make it resistant to failures. Therefore, we want to eliminate the possibility that the fault tolerance of the system will decrease due to the relationship between the networks. Then, in this research, we propose the model of occurrence and propagation of faults on interdependent networks, which is one example of networks that exist in relation to each other. Also, as an example of an interdependent network, we refer to software defined network (SDN).
