According to an embodiment, a communication management apparatus mediates data between an information processing terminal having a temporary memory and an external memory device that is installed outside the information processing terminal. The apparatus includes a receiving unit configured to receive a write request issued by a device other than the information processing terminal for writing the data in the external memory device; a reading-writing unit configured to control reading of the data from the external memory device and control writing of the data in the external memory device; and a delete command issuing unit configured to, when the write request with respect to the external memory device is received, issue a delete command to the information processing terminal for deleting temporary data that is stored in the temporary memory.

Communication management apparatus, communication management method, and computer program product

In one embodiment, a data communication apparatus includes a plurality of communications units for performing transmission and reception with the plurality of different networks, a first storage unit which stores a first identifier and a second identifier, a first processing unit which performs network protocol processing with hardware, and a second processing unit which performs network protocol processing with software. The first identifier indicates a communication unit which receives a frame, and the second identifier indicates a communication unit which transmits a frame. The first processing unit stores the first identifier in association with a reception frame in the first storage unit, and the second processing unit reads the first identifier and the reception frame from the first storage unit, generates a transmission frame as a response to the reception frame, stores the first identifier as the second identifier in association with the transmission frame in the first storage unit.

Data communication apparatus and method

There is provided a bridge device in which a reception unit receives first transfer information specifying a read address from an external device; a transfer information storage stores the first transfer information; a first processing unit generates a first command to instruct reading data from the read address of a data storage based on the first transfer information read from the transfer information storage and outputs the first command to the first controller; a data buffer retains the data read by the first controller from the read address; and a second processing unit generates a second command to instruct the second controller to read the data retained in the data buffer, and outputs the second command to the second controller.

Bridge device with an error tolerant DMA transfer function

There is provided a file transfer device in which a determining unit determines, when a first file requested by a user terminal is not cached in a file buffering unit, a second file transferred to the user terminal based on a file cache status of the file buffering unit, a transfer protocol unit reads the second file from the file buffering unit while the file buffering unit reads the first file, a transmitting unit transmits the second file to the user terminal, wherein the instructing unit determines to transfer the first file, based on a progress status of reading the first file, the transfer protocol unit suspends reading the second file and reads the first file from the file buffering unit, the transmitting unit transmits the first file read by the transfer protocol unit to the user terminal.

File transfer device and method therefor

There is provided a communication device which communicates with a target communication device, including: a communication controller, a general-purpose processing unit, a data transfer processing unit and a starting unit. The general-purpose processing unit communicates with the target communication device via the communication controller. The data transfer processing unit receives data from the target communication device via the communication controller. The starting unit starts up the data transfer processing unit. The general-purpose processing unit receives a data transfer start request from the target communication device. The starting unit starts up the data transfer processing unit when the general-purpose processing unit receives the data transfer start request. The general-purpose processing unit or the data transfer processing unit notifies a data transfer start response to the target communication device after the data transfer processing unit is started up.

Communication device, communication method and computer-readable recording medium

In an information processing device according to an embodiment, a generating unit generates a descriptor including information indicating an area in a storage unit and state information indicating a state of an entry in which the information indicating the area is stored, and an update unit updates the state information according to at least one of writing and reading of data to the area indicated in the entry selected according to the state information by the input/output unit. The generating unit generates the descriptor in advance before at least one of writing and reading of data to/from the storage unit is started.

Information processing device and program product

A main memory data rewriting device includes a rewrite condition analysis unit configured to analyze a rewrite condition for target data in main memory data stored in a main memory before deactivation of an information processing device, and create a first processing content to acquire environment data substituting the target data from outside of the information processing device and a second processing content to rewrite the target data to the environment data, an environment data processing unit configured to acquire the environment data according to the first processing content when the information processing device is temporarily activated at an activation time set to rewrite the target data during a deactivating period of the information processing device, and a rewrite processing unit configured to rewrite a region of a nonvolatile storage medium in which the target data is stored with the environment data according to the second processing content.

Device and method for rewriting main memory data

A relay device is provided that includes a reception unit and a transmission unit. The reception unit receives a startup packet including a magic packet, a MAC address of controllable equipment, and a first ID for starting up the controllable equipment. The transmission unit transmits a first electric signal indicating the first ID to all link-downed Ethernet ports.

Relay device and remote startup system

There is provided with a mixed video delivering apparatus, including: a video receiving unit receiving first to Nth encoded video data from first to Nth terminals; a decoding unit decoding the first to Nth encoded video data; a video mixing unit mixing first to Nth decoded video data to obtain mixed video data to be transmitted to a terminal 'A' out of the first to Nth terminals; an encoding parameter storage storing first to Nth encoding parameters which are used for encoding the first to Nth videos by the first to Nth terminals; an encoding parameter selecting unit selecting an encoding parameter which is used by any one of terminals other than the terminal A; an encoding unit encoding the mixed video data with a selected encoding parameter to obtain encoded mixed video data; and a video transmitting unit transmitting the encoded mixed video data to the terminal A.

Mixed video delivering apparatus and method, and computer storage medium

In a wireless terminal having a wireless transceiver and a wireless receiver which operates with lower power than the wireless transceiver, when the wireless receiver receives, from a base station, a notification message notifying that data addressed to the terminal is existent, the wireless transceiver is turned on to acquire the data.

Wireless terminal, base station, wireless communication system, and wireless communication method

A starting apparatus includes: a storage unit storing an identifier; a rectifying unit rectifying a reception signal; a generating unit comparing the reception signal rectified in the rectifying unit to a reference signal and generating a digital signal from the reception signal; a judging unit judging whether or not the digital signal contains information of the identifier; a reference changing unit changing the reference signal when the judging unit judges that the reception signal does not contain information of the identifier; and a start instructing unit instructing start of an electric appliance when the judging unit judges that the reception signal contains information of the identifier.
