Abstract

An apparatus, upon receiving a first data segment, stores, in a processing queue, a data-segment processing request associated with the first data segment. When the data-segment processing request is extracted from the processing queue, the apparatus performs predetermined processing on the first data segment associated with the data-segment processing request to generate a second data segment, and stores the generated second data segment in a reception buffer provided for each of destinations of data segments. The apparatus stores a holding-stop processing request in the processing queue when the second data segment is stored in the reception buffer being empty, and sends all of one or more second data segments stored in the reception buffer, at once, to a destination associated with the reception buffer when the holding-stop processing request is extracted from the processing queue.

Claims

1. A method for processing received data, the method being performed by a communication apparatus, the method comprising:

upon receiving a first data segment, storing, in a processing queue, a data-segment processing request associated with the first data segment;

performing, when the data-segment processing request is extracted from the processing queue, predetermined processing on the first data segment associated with the data-segment processing request to generate a second data segment; and

storing the generated second data segment in a reception buffer provided for each of destinations of data segments, wherein

a holding-stop processing request is stored in the processing queue when the second data segment is stored in the reception buffer being empty, and

all of one or more second data segments stored in the reception buffer are sent at once to a destination associated with the reception buffer when the holding-stop processing request is extracted from the processing queue.

2. The method of claim 1, further comprising

setting a maximum size of the first data segment, based on a communication protocol used by the communication apparatus, wherein

the second data segment generated from the first data segment having the maximum size is sent to the destination associated with the reception buffer without being stored in the reception buffer.

3. The method of claim 1, further comprising

detecting an event in which a number of the second data segments stored in the reception buffer is a natural number not exceeding a predetermined constant value when the holding-stop processing request is extracted from the processing queue, wherein

when the event has continuously occurred predetermined times, the generated second data segment is sent to the destination associated with the reception buffer without being stored in the reception buffer, for a certain time period.

4. The method of claim 1, further comprising

setting a maximum size of the first data segment, based on a communication protocol used by the communication apparatus, wherein

when the second processing request is extracted from the processing queue just after the data-segment processing request associated with the first data segment having the maximum size has been extracted from the processing queue, the extracted second processing request is added to the processing queue without sending one or more second data segments stored in the reception buffer to the destination associated with the reception buffer.

5. An apparatus for processing received data, the apparatus comprising:

a memory including;

a processing queue for storing, upon receiving a first data segment, a data-segment processing request associated with the first data segment, and

a reception buffer provided for each of destinations of data segments; and

a processor to;

store, in the processing queue, the data-segment processing request associated with the first data segment received by the apparatus, in order in which the first data segment is received by the apparatus;

perform, when the data-segment processing request is extracted from the processing queue, predetermined processing on the first data segment associated with the first processing request to generate a second data segment; and

store the generated second data segment in the reception buffer, wherein

a holding-stop processing request is stored in the processing queue when the second data segment is stored in the reception buffer being empty, and

all of one or more second data segments stored in the reception buffer are sent at once to a destination associated with the reception buffer when the holding-stop processing request is extracted from the processing queue.

6. The apparatus of claim 5, wherein

a maximum size of the first data segment is set based on a communication protocol used by the apparatus, and

the second data segment generated from the first data segment having the maximum size is sent to the destination associated with the reception buffer without being stored in the reception buffer.

7. The apparatus of claim 5, wherein

the processor is configured to detect an event in which a number of the second data segments stored in the data-segment queue does not exceeds a predetermined constant value when the holding-stop processing request is extracted from the processing queue, and

when the event has continuously occurred predetermined times, the generated second data segment is sent to the destination associated with the reception buffer without being stored in the reception buffer, for a certain time period.

8. The apparatus of claim 5, wherein

the processor is configured to set a maximum size of the first data segment, based on a communication protocol used by the communication apparatus;

and

when the second processing request is extracted from the processing queue just after the data-segment processing request associated with the first data segment having the maximum size has been extracted from the processing queue, the extracted second processing request is added to the processing queue without sending one or more second data segments stored in the reception buffer to the destination associated with the reception buffer.

9. A computer readable recording medium having stored therein a program for causing a computer to execute a procedure comprising:

upon receiving a first data segment, storing, in a processing queue, a data-segment processing request associated with the first data segment;

performing, when the data-segment processing request is extracted from the processing queue, predetermined processing on the first data segment associated with the data-segment processing request to generate a second data segment; and

storing the generated second data segment in a reception buffer provided for each of destinations of data segments, wherein

a holding-stop processing request is stored in the processing queue when the second data segment is stored in the reception buffer being empty, and

all of one or more second data segments stored in the reception buffer are sent at once to a destination associated with the reception buffer when the holding-stop processing request is extracted from the processing queue.

10. The computer readable recording medium of claim 9, the procedure further comprising

setting a maximum size of the first data segment, based on a communication protocol used by the communication apparatus, wherein

the second data segment generated from the first data segment having the maximum size is sent to the destination associated with the reception buffer without being stored in the reception buffer.

11. The computer readable recording medium of claim 9, the procedure further comprising

detecting an event in which a number of the second data segments stored in the reception buffer is a natural number not exceeding a predetermined constant value when the holding-stop processing request is extracted from the processing queue, wherein

when the event has continuously occurred predetermined times, the generated second data segment is sent to the destination associated with the reception buffer without being stored in the reception buffer, for a certain time period.

12. The computer readable recording medium of claim 9, the procedure further comprising

setting a maximum size of the first data segment, based on a communication protocol used by the communication apparatus, wherein

when the second processing request is extracted from the processing queue just after the data-segment processing request associated with the first data segment having the maximum size has been extracted from the processing queue, the extracted second processing request is added to the processing queue without sending one or more second data segments stored in the reception buffer to the destination associated with the reception buffer.
