Method for Estimation of Vitality of Allocated Information Systems

Abstract

The method refers to the information security domain of information networks and can be used at a comparative estimation of information networks structures in order to determine their stability to the failures, caused by the impact of random or deliberate interferences. The destination is to improve results reliability of comparative estimation of information networks structures. To achieve technical result the dynamics of impact of random or deliberate interferences on information network nodes and also possibilities on communication recovery between transit nodes of information network are consider. For this purpose values of indexes of availability of information network nodes, time of achievement of critical ratio of "dangerous"and "safe"nodes for each variant of connection of subscribers, and also connectivity of adjacent "dangerous"nodes forming chains, eliminating exchange between subscribers are calculated.
