  • Publication number: 20160277600
    Abstract: A data transfer control device controls a data transfer process based on data transfer requests, and includes a delay time measurement unit, an operation state information acquisition unit, and a transfer control unit. The delay time measurement unit measures a delay time in data transfer occurring in the data transfer process. The operation state information acquisition unit acquires operation state information indicating one of an operating state and a non-operating state of a transfer restricted module that issues the data transfer requests and is subjected to a predetermined restriction in the data transfer. The transfer control unit limits a transmission amount of the data transfer requests issued by the transfer restricted module, if the measured delay time is at least a predetermined threshold and the acquired operation state information indicates the operating state of the transfer restricted module.
