The purpose of the present invention is to appropriately detect propagation delay and the like (minimum delay value) in order to appropriately control a transmission rate of information. Upon input of a measured value of delay that is smaller than a value set as a minimum delay value, a minimum value setting unit () updates the set minimum delay value to the measured value of the delay. Delay refers to the time from transmission of information to arrival at the destination thereof, or the round trip time from transmission of information to receipt of reply information from the destination receiving the information by the originator. A timing determination unit () determines a review timing for reviewing the set minimum delay value on the basis of the measured value of the delay. A minimum value review unit () updates (reviews) the set minimum delay value at the determined review timing. The minimum delay value to be updated is a value calculated using the measured value of the measured delay or a preset initial value.
