Abstract

Embodiments of the present invention provide systems and methods for facilitating communication of data. A method includes communicating data including prioritizing a block of data, setting an indicator in a header of the block of data, transmitting the block of data, and retransmitting the block of data. The indicator indicates that reliable delivery of the block of data is desired. The indicator is set based at least in part on a rule. The indicator is set on a per-message basis. The block of data is retransmitted when a predetermined time has elapsed and when an acknowledgement of delivery of the block of data has not been received.

Claims

1. A method for communicating data, the method including:

prioritizing a block of data;

setting an indicator in a header of the block of data, wherein the indicator indicates that reliable delivery of the block of data is desired, wherein the indicator is set based at least in part on a rule, and wherein the indicator is set on a per-message basis;

transmitting the block of data; and

retransmitting the block of data when a predetermined time has elapsed and when an acknowledgement of delivery of the block of data has not been received.

2. The method of claim 1, wherein the prioritizing step includes inserting the block of data in at least one of a plurality of queues based at least in part on the content of the data.

3. The method of claim 1, wherein the block of data is part of a plurality of blocks of data, wherein at least one other block of data in the plurality of blocks of data does not have an indicator indicating that reliable delivery is desired set.

4. The method of claim 1, wherein the rule is user defined.

5. The method of claim 1, wherein the rule is based at least in part on a mode.

6. The method of claim 1, wherein the block of data is transmitted over a tactical data network.

7. The method of claim 1, wherein the indicator is based at least in part on the content of the block of data.

8. The method of claim 1, wherein the acknowledgment of delivery of the block of data is made at least in part by an acknowledgement message.

9. The method of claim 8, wherein the acknowledgement message is sent by a destination node, wherein the destination node is the recipient of the transmitted block of data.

10. The method of claim 1, further including receiving the block of data over a tactical data network.

11. The method of claim 1, further including receiving the block of data from an application.

12. A data communication system for providing content-based quality of service in a network, the system including:

a communication component, wherein the communication component is adapted to receive a block of data, wherein the communication component is adapted to transmit the block of data;

a prioritization component, wherein the prioritization component is adapted to prioritize the block of data based at least in part on the content of the block of data and a prioritization rule selected from a set of available prioritization rules; and

a reliability component, wherein the reliability component is adapted to set an indicator in the block of data based at least in part on a reliability rule selected from a set of available reliability rules, wherein the reliability component is adapted to send an acknowledgement message based at least in part on a reliability indicator in a received block of data.

13. The system of claim 12, wherein the block of data is received from an application program on the same node as the data communication system.

14. The system of claim 13, wherein the application uses a transport level interface to transparently communicate the block of data to the data communication system.

15. The system of claim 12, furthering including a mode indicator, wherein the mode indicator indicates a current mode.

16. The system of claim 15, wherein the set of available reliability rules is based at least in part on the current mode.

17. The system of claim 15, wherein the reliability component is adapted to process the block of data based at least in part on the current mode.

18. The system of claim 12, wherein the indicator is set on a per-message basis.

19. The system of claim 12, wherein the communication component is adapted to retransmit the data when the reliability component indicates that a predetermined time has elapsed and no acknowledgement message for the data has been received.

20. A computer-readable medium including a set of instructions for execution on a computer, the set of instructions including:

a communication routine, wherein the communication routine is configured to receive data, wherein the communication routine is configured to transmit the data;

a prioritization routine, wherein the prioritization routine is configured to prioritize the data based at least in part on the content of the data; and

a reliability routine, wherein the reliability routine is configured to set an indicator in the data based at least in part on a reliability rule selected from a set of available reliability rules, wherein the reliability routine is configured to send an acknowledgement message based at least in part on a reliability indicator in a received block of data.
