Abstract

A method of combining multiple data streams of a Fibre Channel network by encoding the first, second or more data streams of the Fibre Channel network and merging the encoded first, second or more data streams into a plurality of frames. The encoding comprises creating packets of information from each of the first, second or more data streams and adding (inserting) identification information to each of the plurality of PCM frames.

Claims

1. A method of combining multiple data streams of a Fibre Channel network, said method comprising:

encoding the first and second data streams of the Fibre Channel network; and

merging the encoded first and second data streams into a plurality of frames.

2. The method of claim 1 further comprising providing the plurality of frames to a device.

3. The method of claim 2 wherein the device is a recorder.

4. The method of claim 1 further comprising recording the plurality of frames.

5. The method of claim 1 further comprising processing the recorded plurality of frames thereby processing the data of the streams.

6. The method of claim 5 wherein said processing comprises extracting one of the data streams from the recorded frames.

7. The method of claim 1 wherein the encoding comprises time tagging the data.

8. The method of claim 1 wherein the merging comprises merging the encoded data streams into pulse code modulated (PCM) frames.

9. The method of claim 1 further comprising enabling and filtering the received data streams before the merging of the received data streams.

10. The method of claim 1 wherein encoding includes adding identification information to each of the Fibre Channel streams.

11. The method of claim 1 further comprising:

creating packets of information from each of the first and second data streams; and

adding identification information to each of the frames.

12. The method of claim 11 wherein creating packets comprises:

capturing words of each of the data streams;

determining a content of each of the captured words;

formatting each of the captured words according to its determined content.

13. The method of claim 12 wherein the determining comprises determining whether each of the captured words is a control word or a data word.

14. The method of claim 13 wherein the adding comprises inserting a time indicator into the created packet relating to each of the determined control words.

15. The method of claim 12 wherein the determining comprises determining whether each of the captured words is a start of frame word.

16. The method of claim 15 wherein the adding comprises inserting a start of frame indicator into the created packet relating to each of the determining start of frame words.

17. The method of claim 11 wherein the adding identification information comprises at least one of the following:

inserting a sync pattern into each of the frames;

inserting an increment frame counter into each of the frames;

inserting a current time into each of the frames; and

inserting encoding information into each of the created frames.

18. A method of combining multiple data streams of a Fibre Channel network, said method comprising:

creating packets of information from each of the first and second data streams by;

capturing words of each of the data streams;

determining a content of each of the captured words; and

formatting each of the captured words according to its determined content;

merging the encoded first and second data streams into a plurality of frames; and

adding identification information to each of the frames.

19. The method of claim 18 wherein the determining comprises determining whether each of the captured words is a control word or a data word.

20. The method of claim 19 wherein the adding comprises inserting a time indicator into the created packet relating to each of the determined control words.

21. The method of claim 18 wherein the determining comprises determining whether each of the captured words is a start of frame word.

22. The method of claim 21 wherein the adding comprises inserting a start of frame indicator into the created packet relating to each of the determining start of frame words.

23. The method of claim 18 wherein the adding identification information comprises at least one of the following:

inserting a sync pattern into each of the frames;

inserting an increment frame counter into each of the frames;

inserting a current time into each of the frames; and

inserting encoding information into each of the created frames.

24. A method of combining multiple data streams of a Fibre Channel network, said method comprising:

creating packets of information from each of first and second data streams;

merging the encoded first and second data streams into a plurality of frames; and

adding identification information to each of the frames including at least one of the following;

inserting a sync pattern into each of the frames;

inserting an increment frame counter into each of the frames;

inserting a current time into each of the frames; and

inserting encoding information into each of the created frames.

25. A method of combining multiple data streams of a plurality of avionics units networked with a Fibre Channel network having nodes, at least one node having an interface for transmitting at least some of the multiple data streams, said method comprising:

encoding the transmitted multiple data streams of said at least one node of the Fibre Channel network; and

merging the encoded multiple data streams into a plurality of frames.

26. The method of claim 25 further comprising providing the plurality of frames to a device.

27. The method of claim 26 wherein the device is a recorder.

28. The method of claim 25 further comprising recording the plurality of frames.

29. The method of claim 25 further comprising processing the recorded plurality of frames thereby processing the data of the multiple streams.

30. The method of claim 29 wherein said processing comprises extracting one of the data streams from the recorded frames.

31. The method of claim 25 wherein the encoding comprises time tagging the data.

32. The method of claim 25 wherein the merging comprises merging the encoded data streams into pulse code modulated (PCM) frames.

33. The method of claim 25 further comprising enabling and filtering the received data streams before the merging of the received data streams.
