Abstract

A data delivery system and method of the present invention according to one embodiment includes establishing connections between computers regardless of NAT, transporting data between computers in a reliable fashion, creating a secure stream of packets from stored or streaming data on a server, organizing a plurality of computers to cooperatively transport secure packet streams, transporting and correcting secure packet streams in a cooperative environment, and rendering the original stored or streaming data from a secure packet stream thereby reducing demand on the server.

Claims

1. A data delivery system comprising:

a) a server, connected to a network, containing data in the form of a plurality of packets wherein each packet is identified by masks; and

b) computers connected to said network wherein each of said computers that are identified by said server as peer computers, wherein the identification of peer computers includes identifying open, multi and closed computers using a NAT router, is assigned to receive a specific mask from said server, wherein the specific mask is from the plurality of masks and wherein each peer computer receives a specific mask that is different from the other specific masks received by any other peer computers and each peer computer delivers said received specific mask to all other peer computers such that in combination each peer computer receives one specific mask from said server and a remainder of said packet in the form of other specific masks from the other peer computers and, if there are fewer peer computers than masks, then the remainder of said packet is received from said server.

2. The apparatus of claim 1 wherein said masks are sequentially numbered.

3. The apparatus of claim 2 wherein said peer computers assemble said masks according to sequential numbers.

4. The apparatus of claim 2 further including a request mechanism whereby missing masks from the server are immediately requested from said server and wherein a configurable delay occurs prior to requesting said server to send missing masks sent to other peer computers.

5. The apparatus of claim 4 wherein said request mechanism further includes a periodic check of peer computer availability in order to assign further specific masks to additional peer computers so as to reduce the amount of data sent by said server.

6. The apparatus of claim 1 wherein the identification of peer computers includes identifying open, multi and closed computers using a NAT router.

7. A data delivery method comprising:

a) connecting a server, containing data in the form of packets, to a network wherein

each packet is divided into a plurality of masks;

b) connecting computers to said network and identifying peer computers by said server wherein the identification of peer computers includes identifying open, multi and closed computers using a NAT router;

c) assigning each of said computers that are identified by said server as peer computers to

receive a specific mask from said server, wherein the specific mask is from the plurality of masks and wherein each peer computer receives a specific mask that is different from the other specific masks received by any other peer computers; and

d) each peer computer delivering said received specific mask to all other peer computers such that in combination each peer computer receives one specific mask from said server and a remainder of said packet in the form of other specific masks from the other peer computers and, if there are fewer peer computers than masks, then the remainder of said packet is received from said server.

8. The method of claim 7 wherein said masks are sequentially numbered.

9. The method of claim 8 wherein said peer computers assemble said masks according to sequential numbers.

10. The method of claim 8 further including providing a request mechanism whereby missing masks from the server are immediately requested from said server and wherein a configurable delay occurs prior to requesting said server to send missing masks sent to other peer computers.

11. The method of claim 10 wherein said request mechanism further includes periodically checking peer computer availability in order to assign further specific masks to additional peer computers so as to reduce the amount of data sent by said server.

12. The method of claim 7 further including distributing a descriptor on said network wherein said descriptor includes a global identifier for a specific packet, an address and a port and an available mask.

13. The method of claim 7 wherein said packets include an authentication number such that packets without authentication numbers are rejected by said peer computers.

14. In a computer system including a server containing data connected with a network to other computers, computer code recorded on a computer readable medium for delivering data comprising:

a) computer code for forming said data into packets and identifying said packets by masks;

b) computer code for identifying computers connected to said network as peer computers

and assigning each of said peer computers to receive a specific mask from said server and computer code for identifying open, multi and closed computers using a NAT router, wherein the specific mask is from the plurality of masks and wherein each peer computer receives a specific mask that is different from the other specific masks received by any other peer computers; and

c) computer code for causing each peer computer to deliver said received specific mask to all other peer computers such that in combination each peer computer receives one specific mask from said server and a remainder of said packet in the form of other specific masks from the other peer computers and, if there are fewer peer computers than masks, then the remainder of said packet is received from said server.

15. The invention of claim 14 further including computer code for sequentially numbering said masks.

16. The invention of claim 15 further including computer code enabling said peer computers to assemble said masks according to sequential numbers.

17. The invention of claim 14 further including computer code for distributing a descriptor on said network wherein said descriptor includes a global identifier for a specific packet, an address and a port and an available mask.

18. The invention of claim 14 wherein said computer code for dividing said data into packets includes computer code for adding an authentication number such that packets without authentication numbers are rejected by said peer computers.

19. The invention of claim 14 further including computer code for a request mechanism whereby missing masks from the server are immediately requested from said server and wherein a configurable delay occurs prior to requesting said server to send missing masks sent to other peer computers.

20. The invention of claim 19 wherein said computer code for said request mechanism further includes computer code for periodically checking peer computer availability in order to assign further specific masks to additional peer computers so as to reduce the amount of data sent by said server.
