Abstract

Due to the lack of objectively reflecting the macro situation of large-scale complex network availability, this paper proposes a new definition of availability index for macro situation and its flow-based quantitative calculation method. Three experiments using actual flow data are designed to validate their effectivity. Theoretical analysis and experimental results show that, compared to existing related methods, our proposed index has better objectivity, feasibility and practicability. Moreover, it can more effectively reflect the macro situation of the availability and its evolution and trends over time, and also measure and evaluate the security influences of different events on the availability.
