Abstract

An electronic device includes an input control processing unit that culls first input data by generating second input data from the first input data; an output control processing unit that culls output data; and a congestion control unit that instructs the input control processing unit to increase a quantity of the first input data to be culled, when delay in output relative to input is increasing, and instructs the output control processing unit to increase a quantity of the output data to be culled when the delay in output relative to input continues to increase despite the increase in the quantity of the first input data to be culled.

Claims

1. An electronic device comprising:

an input control processing unit that culls first input data by generating second input data from the first input data;

an output control processing unit that culls output data; and

a congestion control unit that instructs the input control processing unit to increase a quantity of the first input data to be culled, when delay in output relative to input is increasing, and instructs the output control processing unit to increase a quantity of the output data to be culled when the delay in output relative to input continues to increase despite the increase in the quantity of the first input data to be culled.

2. The electronic device according to claim 1, wherein

the congestion control unit instructs the output control processing unit to decrease the quantity of the output data to be culled, when the delay in output relative to input is decreasing and instructs the input control processing unit to decrease the quantity of the first input data to be culled, when the delay in output relative to input continues to decrease irrespective of the decrease in the quantity of the output data to be culled.

3. The electronic device according to claim 1, wherein

the input control processing unit generates the second input data by calculating a moving average of the first input data of a quantity corresponding to the quantity of the first input data to be culled.

4. The electronic device according to claim 1, wherein

the output control processing unit discards from among the second input data to be processed, the second input data of a quantity corresponding to the quantity of the output data to be culled.

5. A control method comprising:

increasing a quantity of first input data to be culled, when delay in output relative input is increasing;

culling the first input data by generating second input data from the first input data based on the quantity of first input data to be culled;

increasing a quantity of output data to be culled when the delay in output relative to input continues to increase despite the increase in the quantity of the first input data to be culled; and

culling the output data based on the quantity of output data to be culled.

6. The control method according to claim 5, comprising:

decreasing the quantity of the output data to be culled when the delay in output relative input is decreasing;

culling the output data based on the quantity of output data to be culled;

decreasing the quantity of the first input data to be culled when the delay in output relative to input continues to decrease irrespective of the decrease in the quantity of the output data to be culled; and

culling the first input data by generating second input data from the first input data based on the quantity of the first input data to be culled.

7. The control method according to claim 5, wherein

the culling of the first input data includes generating the second input data by calculating a moving average of the first input data of a quantity corresponding to the quantity of the first input data to be culled.

8. The control method according to claim 5, wherein

the culling of the output data includes discarding from among the second input data to be processed, the second input data of a quantity corresponding to the quantity of the output data to be culled.

9. A computer-readable recording medium storing a program causing an electronic device to execute a control process comprising:

increasing a quantity of first input data to be culled, when delay in output relative input is increasing;

culling the first input data by generating second input data from the first input data based on the quantity of first input data to be culled;

increasing a quantity of output data to be culled when the delay in output relative to input continues to increase despite the increase in the quantity of the first input data to be culled; and

culling the output data based on the quantity of output data to be culled.

10. The computer-readable recording medium according to claim 9, the control process comprising:

decreasing the quantity of the output data to be culled when the delay in output relative input is decreasing;

culling the output data based on the quantity of output data to be culled;

decreasing the quantity of the first input data to be culled when the delay in output relative to input continues to decrease irrespective of the decrease in the quantity of the output data to be culled; and

culling the first input data by generating second input data from the first input data based on the quantity of the first input data to be culled.

11. The computer-readable recording medium according to claim 9, wherein

the culling of the first input data includes generating the second input data by calculating a moving average of the first input data of a quantity corresponding to the quantity of the first input data to be culled.
