BIT RATE INDICATION DEVICE, BIT RATE INDICATION METHOD AND RECORDING MEDIUM IN WHICH BIT RATE INDICATION PROGRAM IS RECORDED

摘要

Provided is a bit rate indication device, etc., with which it is possible to improve the quality of communication of information in a short time via a communication network. A bit rate indication device 91 has: a quality model creation unit 92 for creating a quality model that represents the degree of a change of quality of communication with the passage of time on the basis of a bit rate model in bit rate information that includes a plurality of bit rate models representing the degree of a change with the passage of time of a data volume per unit time pertaining to data communicated via a communication network 3 and an available band model representing the degree of a change with the passage of time of a communication band pertaining to the communication network 3; and a bit rate indication unit 93 for finding an expected value pertaining to the created quality model on the basis of a probability that the available band model will occur, and indicating to a control device that controls the communication so as to control the data volume per unit time in accordance with a bit rate model the expected value of which is larger than other bit rate models among the plurality of bit rate models included in the bit rate information.
