Abstract

This study proposes a method that measures the stability of networks by converting nodes with higher priorities into virtual articulation nodes. Further, although they're not articulation nodes, by considering critical nodes such as routers connected to external networks or servers that assume vital operations to networks, we are able to improve the monitoring of major nodes in networks and reallocate those nodes when designing networks in order to remove potential risk factors. We will elaborate on the method of creating virtual articulation nodes using virtual nodes and apply them to network topologies to perform a stability analysis through simulation.
