Abstract: Provided is a delay prediction device for predicting a future communication delay with high accuracy based on past communication delay data. Delay prediction device includes: a low delay distribution estimation unit that estimates a probability distribution of a first communication delay state by using a result of measuring a communication delay of a packet in a network; identification unit that identifies whether a state of the communication delay is the first communication delay state or a second communication delay state in which the communication delay is greater than the communication delay in the first communication delay state; high delay distribution estimation unit that estimates a probability distribution of the second communication delay state; and delay distribution prediction unit that predicts a probability distribution of a future communication delay, based on a probability distribution of the first communication delay state and a probability distribution of the second communication delay state.
