Abstract

An information processing method includes calculating a reception estimated time when the data are received based on a last reception time of the data and a reception time interval of the data for transfer source devices; calculating a shift completion estimated time based on a shift time period necessary to shift an assignment of a data transfer process of a transfer source device of the plurality of the transfer source devices from the transfer processing device to another transfer processing device; and transferring the assignment of the data transfer process from the transfer processing device to the another transfer processing device, the assignment of the data transfer process being relevant to a transfer source device having the calculated reception estimated time later than the shift completion estimated time and closer to the shift completion estimated time than any other transfer source devices.
