Document Type and Number:
Japanese Patent JP6927417
Kind Code:
B2
Abstract:
To realize real-time estimation when estimating the type and state of an application from time-series data of communication traffic. A communication traffic analyzing apparatus of the present invention has a state transition model generating unit configured to generate a probabilistic state transition model from time-series data of communication traffic, at each predetermined timing, a state transition model update unit configured to update a state transition model when a difference between the state transition models at two timings generated by the state transition model generating unit is greater than or equal to a predetermined difference and a communication state of network satisfies a predetermined condition, and an application type and state estimating unit configured to estimate a type and a state of an application using the updated state transition model.
