Abstract

A methodology is provided for transferring a file from a first entity to a second entity over a network. The methodology may include receiving a first one of a plurality of blocks at the second entity, receiving a second one of said plurality of blocks at the second entity, receiving a last one of the plurality of blocks at the second entity, and assembling the first one of the plurality of blocks and the second one of the plurality of blocks into a single file at the second entity after receiving the last one of the plurality of blocks.

Claims

1. A method of transferring a file over a network comprising:

dividing a file into a plurality of blocks;

transferring a first one of said plurality of blocks from a first entity and across said network toward a second entity;

transferring a second one of said plurality of blocks from said first entity and across said network toward said second entity while said first one of said plurality of blocks is being transferred across said network to said second entity and

repeating said transferring of said subsequent one of said plurality of blocks until all of said plurality of blocks have been transferred wherein at least one of said plurality of blocks comprises an intercontrol block that contains information for rebuilding the file from said plurality of blocks.

2. The method of claim 1, wherein said method utilizes Transmission Control Protocol (TCP) for transmission of said first one of said plurality of blocks and for transmission of said second one of said plurality of blocks.

3. The method of claim 2, wherein said method further utilizes a file transfer protocol (FTP) methodology for transmission of said first one of said plurality of blocks and for transmission of said second one of said plurality of blocks.

4. The method of claim 1, wherein dividing said file comprises determining whether said file is larger than a predetermined size.

5. The method of claim 1, wherein transferring said second one of said plurality of blocks comprises waiting a predetermined time after transmission of said first one of said plurality of blocks.

6. The method of claim 1, wherein transferring said second one of said plurality of blocks comprises waiting a predetermined time after a beginning of transmission of said first one of said plurality of blocks.

7. The method of claim 1, further comprising receiving said first one of said plurality of blocks at said second entity.

8. The method of claim 7, further comprising receiving said second one of said plurality of blocks at said second entity.

9. The method of claim 8, further comprising assembling said plurality of blocks at said second entity.

10. The method of claim 9, wherein said plurality of blocks are assembled at said second entity after said second entity receives said intercontrol block from said first entity.

11. The method of claim 1, further comprising said second entity transferring an acknowledgement across said network to said first entity after a beginning of transmission of said second one of said plurality of blocks.

12. The method of claim 1, wherein said file comprises a video file.

13. A method of transferring a file from a first entity to a second entity over a network, said method comprising:

receiving a first one of a plurality of blocks at said second entity;

receiving a second one of said plurality of blocks at said second entity;

receiving subsequent ones of said plurality of blocks at said second entity until all of said plurality of blocks have been received at said second entity, wherein said at least one of said plurality of blocks comprises an intercontrol block that contains information for rebuilding the file from said plurality of blocks; and

assembling said plurality of blocks into a single file at said second entity based on the intercontrol block.

14. The method of claim 13, wherein said method utilizes Transmission Control Protocol (TCP) for transmission/reception of said first one of said plurality of blocks and for transmission/reception of said second one of said plurality of blocks.

15. The method of claim 14, wherein said method further utilizes a file transfer protocol (FTP) methodology for transmission/reception of said first one of said plurality of blocks and for transmission/reception of said second one of said plurality of blocks.

16. The method of claim 13, wherein a last one of said plurality of blocks is said intercontrol block.

17. The method of claim 13, further comprising:

dividing a file into said plurality of blocks;

transferring said first one of said plurality of blocks from said first entity to said second entity; and

transferring said second one of said plurality of blocks from said first entity to said second entity while said first one of said plurality of blocks is being transferred across said network to said second entity.

18. The method of claim 17, wherein transferring said second one of said plurality of blocks comprises waiting a predetermined time after transmission of said first one of said plurality of blocks.

19. The method of claim 17, wherein transferring said second one of said plurality of blocks comprises waiting a predetermined time after a beginning of transmission of said first one of said plurality of blocks.

20. The method of claim 13, further comprising said second entity transferring an acknowledgment across said network to said first entity after a beginning of transmission of said second one of said plurality of blocks.

21. The method of claim 13, wherein said file comprises a video file.

22. A method of transferring a file over a network comprising:

dividing a file into a plurality of blocks;

transferring a first one of said plurality of blocks from a first entity and across said network toward a second entity, said transferring being done in accordance with a Transmission Control Protocol;

transferring a second one of said plurality of blocks from said first entity and across said network toward said second entity while said first one of said plurality of blocks is being transferred across said network to said second entity, said transferring of said second one of said plurality of blocks being done in accordance with said Transmission Control Protocol;

transferring a subsequent one of said plurality of blocks from said first entity across said network toward said second entity while at least one previous block is being transferred across said network to said second entity; and

repeating said transferring of said subsequent one of said plurality of blocks until all of said plurality of blocks have been transferred, wherein at least one of said plurality of blocks comprises an intercontrol block that contains information for rebuilding the file from said plurality of blocks.

23. The method of claim 22, wherein dividing said file comprises determining whether said file is larger than a predetermined size.

24. The method of claim 22, wherein transferring said second one of said plurality of blocks comprises waiting a predetermined time after transmission of said first one of said plurality of blocks.

25. The method of claim 22, wherein transferring said second one of said plurality of blocks comprises waiting a predetermined time after a beginning of transmission of said first one of said plurality of blocks.

26. The method of claim 22, further comprising said second entity transferring an acknowledgment across said network to said first entity after a beginning of transmission of said second one of said plurality of blocks.

27. The method of claim 22, wherein said file comprises a video file.

28. A program storage deice readably by machine, tangibly embodying a program of instructions executable by the machine to perform a method of transferring a file over a network, said method comprising:

dividing a file into a plurality of blocks;

transferring a first one of said plurality of blocks from a first entity and across said network toward a second entity; and

transferring a second one of said plurality of blocks from said first entity and across said network toward said second entity while said first one of said plurality of blocks is being transferred across said network to said second entity;

transferring a subsequent one of said plurality of blocks from said first entity across said network toward said second entity while at least one previous block is being transferred across said network to said second entity; and

repeating said transferring of said subsequent one of said plurality of blocks until all of said plurality of blocks have been transferred, wherein at least one of said plurality of blocks comprises an intercontrol block that contains information for rebuilding the file from said plurality of blocks.
