Abstract

There is provided a packet transmission control device including a packet interval adjustment unit that adjusts packet intervals of a plurality of packets, a packet replication unit that replicates the plurality of packets whose packet intervals are adjusted by the packet interval adjustment unit to generate a plurality of packet groups, and a destination assignment unit that assigns different destination information pieces to the respective plurality of packet groups generated by the packet replication unit.

Claims

1. A packet transmission control device comprising:

a packet interval adjustment unit that adjusts packet intervals of a plurality of packets;

a packet replication unit that replicates the plurality of packets whose packet intervals are adjusted by the packet interval adjustment unit to generate a plurality of packet groups; and

a destination assignment unit that assigns different destination information pieces to the respective plurality of packet groups generated by the packet replication unit.

2. The packet transmission control device according to claim 1, further comprising:

a destination management unit that retains destination management information in which destination information pieces are described, by the destination assignment unit, in order of being assigned to the packet groups,

wherein the packet replication unit replicates a number of packet groups corresponding to a number of destination information pieces described in the destination management information retained by the destination management unit, and

wherein the destination assignment unit assigns, to the packet groups, the destination information pieces described in the destination management information in order of being described in the destination management information.

3. The packet transmission control device according to claim 2, wherein the destination management unit limits the number of destination information pieces that are deleted to be lower than or equal to a predetermined number in accordance with a deletion request for the destination information pieces described in the destination management information.

4. The packet transmission control device according to claim 3, wherein the destination management unit deletes the destination information pieces in order of being described closer to an end of the destination management information.

5. The packet transmission control device according to claim 2, wherein the destination management unit adds a destination information piece to an end of the destination management information in accordance with an addition request of the destination information piece to the destination management information.

6. The packet transmission control device according to claim 1, further comprising:

a destination resolution unit that decides a communication interface that sends the packets based on the destination information piece assigned to the packets by the destination assignment unit.

7. The packet transmission control device according to claim 1, further comprising:

a reception unit that receives packets via a network; and

a buffer unit that temporarily stores the packets received by the reception unit,

wherein the packet interval adjustment unit adjusts packet intervals of packets acquired from the buffer unit.

8. A packet transmission control method comprising:

adjusting packet intervals of a plurality of packets;

replicating the plurality of packets whose packet intervals are adjusted in the step of adjusting the packet intervals to generate a plurality of packet groups; and

assigning different destination information pieces to the respective plurality of generated packet groups.

9. A program for causing a computer to function as:

a packet replication unit that replicates a plurality of packets whose packet intervals are adjusted in advance to generate a plurality of packet groups; and

a destination assignment unit that assigns different destination information pieces to the respective plurality of packet groups generated by the packet replication unit.
