Delay prediction device, delay prediction system, delay prediction method, and recording medium

摘要

Provided is a delay prediction device that predicts a future communication delay with high accuracy based on past communication delay data. The delay prediction device 10b includes a low delay distribution estimating unit 11 that estimates a probability distribution of a first communication delay state using a result of measuring a communication delay of a packet in a network, and a communication delay state that is a first communication delay state. An identification unit 12 for identifying whether the communication delay state is a second communication delay state having a communication delay greater than the first communication delay state, a high delay distribution estimation unit 13 for estimating a probability distribution of the second communication delay state, A delay distribution prediction unit for predicting a probability distribution of a future communication delay based on the probability distribution of the first communication delay state and the probability distribution of the second communication delay state;
