Abstract

A system, non-transitory machine readable medium and method of delayed packetization of data packets is disclosed. The system and method includes requesting authorization from a QoS queue to transmit an intended data packet over a network, wherein the authorization request is sent from an application module of a transmitting network device. The system and method includes receiving from the QoS queue a transmission order to transmit the intended data packet at a future time. The system and method includes packetizing the intended data packet in accordance with the transmission order at the future time. The system and method includes transmitting the packetized data packet over a network to a receiving network device.

Claims

1. A method of packetization of data packets, the method comprising:

requesting authorization from a QoS queue to transmit an intended data packet over a network, where the authorization request is sent from an application module of a transmitting network device;

receiving from the QoS queue a transmission order to transmit the intended data packet at a future time;

packetizing the intended data packet in accordance with the transmission order at the future time; and

transmitting the packetized data packet over a network to a receiving network device.

2. The method of claim 1, wherein the packetized data packet contains time sensitive logic associated with a transmission time.

3. The method of claim 1, wherein the transmitting network device provides queue specific information of the data packet when requesting authorization from the QoS queue.

4. The method of claim 1, wherein the transmitting network device does not provide content of the data packet when requesting authorization from the QoS queue.

5. The method of claim 1, wherein the packetized data packet is different than the intended data packet.

6. The method of claim 1, wherein the transmitting network device decides what data packet to write in accordance at the future time with the transmission order based on one or more policy parameters.

7. The method of claim 1, wherein the QoS queue is configured to implement rate shaping functionality.

8. A non-transitory machine readable medium having stored thereon instructions for packetization of data packets, comprising machine executable code which when executed by at least one machine, causes the machine to:

request authorization from a QoS queue to transmit an intended data packet over a network, where the authorization request is sent from an application module of a transmitting network device;

receive from the QoS queue a transmission order to transmit the intended data packet at a future time;

packetize the intended data packet in accordance with the transmission order at the future time; and

transmit the packetized data packet over a network to a receiving network device.

9. The machine readable medium of claim 8, wherein the packetized data packet contains time sensitive logic associated with a transmission time.

10. The machine readable medium of claim 8, wherein the transmitting network device provides queue specific information of the data packet when requesting authorization from the QoS queue.

11. The machine readable medium of claim 8, wherein the transmitting network device does not provide content of the data packet when requesting authorization from the QoS queue.

12. The machine readable medium of claim 8, wherein the packetized data packet is different than the intended data packet.

13. The machine readable medium of claim 8, wherein the transmitting network device decides what data packet to write in accordance at the future time with the transmission order based on one or more policy parameters.

14. The machine readable medium of claim 8, wherein the QoS queue is configured to implement rate shaping functionality.

15. A network device comprising:

a network interface configured to transmit and receive data packets over a network, the network interface including a QoS queue;

a memory having stored therein instructions to delay packetization of data packets;

a processor coupled to the network interface and the memory, the processor executing the instructions in the memory which cause the processor to;

request authorization from the QoS queue to transmit an intended data packet over a network, where the authorization request is sent from an application module of a transmitting network device;

receive from the QoS queue a transmission order to transmit the intended data packet at a future time;

packetize the intended data packet in accordance with the transmission order at the future time; and

transmit the packetized data packet over a network to a receiving network device.

16. The network device of claim 15, wherein the packetized data packet contains time sensitive logic associated with a transmission time.

17. The network device of claim 15, wherein the transmitting network device provides queue specific information of the data packet when requesting authorization from the QoS queue.

18. The network device of claim 15, wherein the transmitting network device does not provide content of the data packet when requesting authorization from the QoS queue.

19. The network device of claim 15, wherein the packetized data packet is different than the intended data packet.

20. The network device of claim 15, wherein the transmitting network device decides what data packet to write in accordance at the future time with the transmission order based on one or more policy parameters.

21. The network device of claim 15, wherein the QoS queue is configured to implement rate shaping functionality.
