According to one embodiment, a communication control device includes processing circuitry. The processing circuitry acquires at least either; wired communication characteristic information or wireless communication characteristic information from relaying devices or, storage characteristic information indicating usage of a plurality of storage devices storing data units that are transferred via the relaying devices and sent or received by a terminal in the wireless network or, data characteristic information indicating states of a plurality of data units stored in each of the storage devices. The processing circuitry is configured to receive a data acquisition request or a data saving request sent from the terminal and specify a relaying device or a storage device that processes the data acquisition request or the data saving request, and sends an instruction to the terminal, instructing to transmit the data acquisition request or the data saving request to the specified relaying device or the storage device.
