Transfer control device, transfer control method, and computer program product

. The transfer control device according to claim 1, wherein

• when a of data red in the first transmission buffer and having degree of priority to be equal to or greater than a priority threshold value is smaller than a data size threshold value, the determining unit determines that data having a smaller degree of priority than the priority threshold value is to be restricted from being transferred, and
• when the size of data stored in the first transmission buffer and having the degree of priority to be equal to or greater than the priority threshold value is equal to or greater than the data size threshold value, the determining unit determines that data having the degree of priority to be smaller than the priority threshold value is not to be restricted from being transferred.

The transfer control device according to claim wherein

• the determining unit refers to the scheduling information, calculates a number of pieces of data that are transmittable from the first transmission buffer at next transmission timing, and
• when a number of pieces of data stored in the first transmission buffer is smaller than the number of transmittable pieces of data, pieces that data having the degree of priority to be smaller than the priority threshold value is to be restricted from being transferred, and
• when data having the degree of priority to be smaller than the priority threshold value is to be restricted from being transferred, the control unit delays transfer of data having the degree of priority to be smaller than the priority threshold value.
