Abstract

Certain embodiments of the present invention provide for a method for data communication including determining protocol information for a block of data, prioritizing the block of data, and communicating the block of data. The protocol information may include information used by a protocol to communicate the block of data. The prioritization may be based at least in part on the protocol information. The communication may be based at least in part on the prioritization of the block of data.

Claims

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

determining protocol information for at least first and second blocks of data, wherein the protocol information includes information used by a protocol to communicate the blocks of data;

prioritizing at least the first and second blocks of data by enquiring the blocks of data in at least one queue based at least in part on the protocol information; and

communicating the blocks of data based at least in part on the prioritizations of the blocks of data, wherein the order in which the blocks of data are communicated is based on the prioritizing step.

2. The method of claim 1, further including the step of receiving the blocks of data.

3. The method of claim 2, wherein the blocks of data are received at least in part over a tactical data network.

4. The method of claim 1, wherein the blocks of data include a header and a payload.

5. The method of claim 1, wherein at least one of the blocks of data is non-contiguous in memory.

6. The method of claim 1, wherein the prioritizing step includes prioritizing at least the first and second blocks of data based at least in part on a mode indicator associated with one or more of the blocks of data.

7. The method of claim 1, wherein the blocks of data are organized in at least one queue.

8. The method of claim 1, wherein the communicating step includes transmitting the blocks of data at least in part over a tactical data network.

9. The method of claim 1, wherein the communicating step includes passing the blocks of data to an application program.

10. The method of claim 1, wherein the order is determined based at least in part on a range of addresses.

11. The method of claim 1, wherein the order is determined based at least in part on a user defined rule.

12. The method of claim 11, wherein the rule is based at least in part on a mode.

13. The method of claim 1, wherein the prioritizing step is transparent to an application program.

14. A system for data communication, the system including:

a prioritization component adapted to determine a first priority for a first block of data and a second priority for a second block of data in at least one queue, the first and second blocks of data each including protocol information, wherein the first and second priorities are determined based at least in part on the protocol information; and

a communication component adapted to communicate the first block of data before at least the second block of data based at least in part on the priority of the first block of data.

15. The system of claim 14, wherein the blocks of data are received at least in part over a tactical data network.

16. The system of claim 14, wherein the at least one queue is adapted to organize one or more of available blocks of data based at least in part on the priority of the available blocks of data.

17. The system of claim 14, wherein the communication component is adapted to communicate the blocks of data to an application program.

18. The system of claim 14, further including a mode indicator, wherein the mode indicator indicates a current mode, wherein the prioritization component is adapted to prioritize the blocks of data based at least in part on the mode indicator.

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

a protocol information determination routine configured to determine protocol information for first and second blocks of data;

a prioritization routine configured to determine a priority for each of the first and second blocks of data based at least in part on the protocol information; and

a communication routine configured to communicate the first block of data before at least the second block of data, wherein the order in which the blocks of data are communicated is based on the priority for each block of data.

20. The set of instructions of claim 19, wherein the priority for each block of data is determined by enquiring the blocks of data in at least one queue.
