Abstract

A data management system comprises a plurality of data transfer paths and a responder adapted to receive from an originator a data segment from each of a predetermined set of the data transfer paths. The system also comprises a context manager adapted to reassemble the data segments into a data communication based on the predetermined set of data transfer paths and a mapping order of the data segments.

Claims

1. A data management system, comprising:

a plurality of data transfer paths;

a responder adapted to receive from an originator a data segment from each of a predetermined set of the data transfer paths; and

a context manager adapted to reassemble the data segments into a data communication based on the predetermined set of data transfer paths and a mapping order of the data segments.

2. The system of claim 1, wherein the responder comprises a plurality of transceivers coupled to each of the data transfer paths.

3. The system of claim 1, wherein the responder comprises a reassembly buffer adapted to store the data segments.

4. The system of claim 1, wherein the responder comprises a plurality of reassembly buffers each adapted to store a portion of the data segments.

5. The system of claim 4, further comprising a synchronizer adapted to synchronize assembly of the data segments from each of the reassembly buffers.

6. The system of claim 5, wherein the synchronizer is further adapted to retrieve the stored data segments from each of the reassembly buffers in parallel.

7. The system of claim 4, further comprising a plurality of intermediate synchronizers each adapted to synchronize assembly of the data segments at a predetermined set of the reassembly buffers.

8. The system of claim 7, further comprising a master synchronizer adapted to synchronize assembly of the data segments corresponding to each of the intermediate synchronizers.

9. The system of claim 8, wherein master synchronizer is further adapted to retrieve the stored data segments from each of the reassembly buffers in parallel.

10. The system of claim 1, wherein the context manager is further adapted to designate a particular address of a buffer to receive the data segments.

11. The system of claim 1, wherein the context manager is further adapted to designate a particular address for each of a plurality of buffers to receive the data segments.

12. A method for data communication, comprising:

receiving from an originator a plurality of data segments on a predetermined set of data transfer paths;

determining a mapping order of the data segments corresponding to the predetermined set of data transfer paths; and

assembling the data segments into a data communication based on the predetermined set of data transfer paths and the mapped order.

13. The method of claim 12, further comprising storing the data segments in a plurality of reassembly buffers.

14. The method of claim 13, further comprising synchronizing assembly of the data segments from each of the reassembly buffers.

15. The method of claim 12, further comprising retrieving in parallel the data segments from each of a plurality of reassembly buffers.

16. The method of claim 12, further comprising designating a particular address of each of a plurality of buffers for receiving the data segments.

17. The method of claim 16, wherein designating comprises designating the particular address upon receipt of a first data segment.

18. A data management system, comprising:

a plurality of reassembly buffers each adapted to store a data segment;

a plurality of intermediate synchronizers each adapted to synchronize assembly of the data segments for at least one of the reassembly buffers; and

a master synchronizer adapted to retrieve in parallel the data segments from each of the reassembly buffers after synchronization by the intermediate synchronizers.

19. The system of claim 18, further comprising a context manager adapted to designate an address for each of the plurality of reassembly buffers.

20. The system of claim 19, wherein the context manager is adapted to designate the address upon receipt of a first of the data segments.

21. The system of claim 18, further comprising a plurality of transceivers adapted to receive the data segments from a plurality of data transfer paths.

22. The system of claim 21, further comprising a context manager adapted to determine a predetermined set of the plurality of data transfer paths based on an originator of the data segments.

23. A data management system, comprising:

means for receiving a plurality of data segments from an originator;

means for determining a predetermined set of the receiving means;

means for determining a mapping order of the data segments; and

means for reassembling the data into a data communication based on the predetermined set of receiving means and the mapping order.

24. The system of claim 23, further comprising means for storing the data segments.

25. The system of claim 23, further comprising means for synchronizing reassembly of the data segments into the data communication.

26. The system of claim 23, further comprising means for allocating a plurality of buffers for storing the data segments.

27. The system of claim 23, further comprising means for retrieving the data segments in parallel from a plurality of buffers.

28. The system of claim 23, further comprising means for determining a quantity of the data segments corresponding to the data communication.
