Abstract

A data-transmission-control system for transmitting data packets includes a classifier to separate control packets from other packets, and an output device to transmit packets, wherein the classifier triggers the output device to directly send the separated control packets upon receiving and separating the control packets in a communication link implementing a Transmission Control Protocol, and the classifier sends the other packets to a packet processing or scheduling device.

Claims

1. A data-transmission-control system for transmitting data packets, comprising:

a classifier for separating control packets from other packets; and

an output device for transmitting the control packets and other packets, the classifier triggering the output device to send the separated control packets upon receiving and separating the control packets.

2. The data-transmission-control system as claimed in claim 1, wherein the data-transmission-control system transmits data packets in a communication link implementing a Transmission Control Protocol.

3. The data-transmission-control system as claimed in claim 1, wherein the classifier sends the other packets to a packet processing or scheduling device.

4. The data-transmission-control system as claimed in claim 1 further comprises a control packet queue for storing the control packets, wherein the classifier sends the control packets to the control packet queue upon receiving and separating the control packets.

5. The data-transmission-control system as claimed in claim 1, wherein the control packets are Transmission-Control-Protocol control packets.

6. The data-transmission-control system as claimed in claim 1, wherein the control packets are packets of a size smaller than or equal to a predetermined size.

7. The data-transmission-control system as claimed in claim 1, wherein the classifier separates only control packets, sends the separated control packets to the control packet queue, and triggers the output device to transmit the separated control packets

8. The data-transmission-control system as claimed in claim 1, wherein the classifier only separates packets of a predetermined size, sends the separated packets of the predetermined size to the control packet queue, and triggers the output device to transmit the separated packets of the predetermined size.

9. A data-transmission-control system for transmitting data packets in a communication link, comprising:

a classifier for separating control packets and for sending other packets to a packet processing or scheduling device;

a control packet queue for storing the separated control packets, the classifier sending the separated control packets to the control packet queue upon receiving and separating the control packets; and

an output device for transmitting the control packets and other packets, the classifier triggering the output device to directly transmit the separated control packets upon receiving and separating the control packets.

10. The data-transmission-control system as claimed in claim 9, wherein the communication link implements a Transmission Control Protocol.

11. The data-transmission-control system as claimed in claim 9, wherein the packet processing or scheduling device is a Quality of Service processing device.

12. The data-transmission-control system as claimed in claim 9, wherein the control packets are Transmission-Control-Protocol control packets.

13. The data-transmission-control system as claimed in claim 9, wherein the control packets are packets of a size smaller than or equal to a predetermined size.

14. The data-transmission-control system as claimed in claim 9, wherein the classifier separates only control packets, sends the separated control packets to the control packet queue, and triggers the output device to transmit the separated control packets.

15. The data-transmission-control system as claimed in claim 9, wherein the classifier separates only packets of a predetermined size, sends the separated packets of the predetermined size to the control packet queue, and triggers the output device to transmit the separated packets of the predetermined size.

16. A data-transmission-control method for transmitting data packets, comprising:

classifying the data packets;

separating control packets from other packets; and

transmitting the control packets, bypassing other packet processing or scheduling devices.

17. The data-transmission-control method as claimed in claim 16, wherein the data-transmission-control method transmits data packets in a communication link implementing a Transmission Control Protocol.

18. The data-transmission-control method as claimed in claim 16, further comprising a step of sending the other packets to a packet processing or scheduling device.

19. The data-transmission-control method as claimed in claim 16, further comprising a step of storing the separated control packets before transmitting the control packets.

20. The data-transmission-control method as claimed in claim 16, wherein the control packets are Transmission-Control-Protocol control packets.

21. The data-transmission-control method as claimed in claim 16, wherein the method separates only packets of a predetermined size in the classifying step and transmits only the packets of the predetermined size.

22. A data-transmission-control method for transmitting data packets in a communication link, comprising:

classifying the data packets;

separating control packets from other packets;

sending the other packets to a Quality of Service processing device;

storing the control packets; and
