Abstract

An information processing apparatus includes a data receiver that receives data from one or more apparatuses, processing circuitry that determines a transfer priority of the data received by the data receiver based on data type, and a data transmitter that transfers the data to apparatuses other than the apparatus that transferred the data in accordance with the transfer priority. The processing circuitry determines if there is any data that has not been transferred during a predetermined data transfer period, and, based on determination indicating that there is data that has not been transferred, modifies the transfer priority of the data that has not been transferred to have a transfer priority higher than that of data to be transferred next, to cause the data transmitter to transfer the data having the modified transfer priority preferentially to apparatuses other than the apparatus that transferred the data.

Claims

1. An information processing apparatus, comprising:

a data receiver to receive data from one or more apparatuses;

processing circuitry to determine a transfer priority of the data received by the data receiver based on data type; and

a data transmitter to transfer the data to apparatuses other than the apparatus that transferred the data in accordance with the transfer priority,

wherein the processing circuitry determines if there is any data that has not been transferred during a predetermined data transfer period, and, based on determination indicating that there is data that has not been transferred, modifies the transfer priority of the data that has not been transferred to have a transfer priority higher than that of data to be transferred next, to cause the data transmitter to transfer the data having the modified transfer priority preferentially to apparatuses other than the apparatus that transferred the data.

2. The information processing apparatus according to claim 1, further comprising an information storing unit to store data priority information that associates the data type with the transfer priority of the data,

wherein the processing circuitry determines the transfer priority with reference to the data priority information.

3. The information processing apparatus according to claim 1, further comprising a history storing unit to store information on data that the data transmitter transfers as history information,

wherein the processing circuitry determines whether or not the data that has not been transferred is within the predetermined data transfer period with reference to the history information.

4. The information processing apparatus according to claim 1, wherein the predetermined data transfer period is specified in accordance with the data type.

5. The information processing apparatus according to claim 1, further comprising a data storing unit to store data that the data receiver receives,

wherein the processing circuitry retrieves the data stored in the data storing unit, determines the transfer priority of the data, stores the data while rearranging the data in accordance with the determined transfer priority, retrieves first data to be arranged in accordance with the transfer priority from the data storing unit, and passes the retrieved data to the data transmitter.

6. The information processing apparatus according to claim 1, further comprising a data storing unit to store data received by the data receiver in accordance with the transfer priority determined by the processing circuitry,

wherein the data transmitter retrieves and transfers first data to be arranged in accordance with the transfer priority from the data storing unit.

7. The information processing apparatus according to claim 1, wherein the processing circuitry determines the transfer priority in response to data reception by the data receiver or data transmission by the data transmitter and determines whether or not the data that has not been transferred is within the predetermined data transfer period.

8. An information processing system, comprising:

multiple apparatuses; and

an information processing apparatus to control communication among the multiple apparatuses, the information processing apparatus comprising;

a data receiver to receive data from one or more apparatuses;

processing circuitry to determine a transfer priority of the data received by the data receiver based on data type; and

a data transmitter to transfer the data to apparatuses other than the apparatus that transferred the data in accordance with the transfer priority,

wherein the processing circuitry determines if there is any data that has not been transferred during a predetermined data transfer period, and, based on determination indicating that there is data that has not been transferred, modifies the transfer priority of the data that has not been transferred to have a transfer priority higher than that of data to be transferred next, to cause the data transmitter to transfer the data having the modified transfer priority preferentially to apparatuses other than the apparatus that transferred the data.

9. A method of controlling communication in an information processing system, comprising the steps of:

receiving data from one or more apparatuses in the information processing system;

determining a transfer priority of the data received based on data type;

transferring the data to apparatuses other than the apparatus that transferred the data in accordance with the transfer priority;

determining if there is any data that has not been transferred during a predetermined data transfer period; and

based on determination indicating that there is data that has not been transferred, modifying the transfer priority of data that has not been transferred to have a transfer priority higher than that of data to be transferred to next; and

transferring the data having the modified transfer priority preferentially to apparatuses other than the apparatus that transferred the data.
