Abstract

A method, computer-readable medium and data processing system for replicating streaming content in a peer-to-peer network is provided. A first client of the peer-to-peer network receives streaming content encapsulated in one or more data blocks formatted according to a transport format of the peer-to-peer network. The first client extracts the streaming content from the one or more data blocks and assembles the streaming content into a native format of the streaming content. The streaming content is stored in the native format. The first client conveys at least a portion of the streaming content in the native format to a second client external to the peer-to-peer network.

Claims

1. A method of replicating streaming content in a peer-to-peer network, comprising:

receiving, by a first client of the peer-to-peer network, streaming content encapsulated in one or more data blocks formatted according to a transport format of the peer-to-peer network;

extracting the streaming content from the one or more data blocks;

assembling the streaming content into a native format of the streaming content;

storing the streaming content in the native format; and

conveying at least a portion of the streaming content in the native format to a second client external to the peer-to-peer network.

2. The method of claim 1, further comprising receiving, by the first client, a peer list of connectivity information of one or more nodes in the peer-to-peer network, wherein the streaming content is received from at least one of the one or more nodes.

3. The method of claim 2, wherein receiving the peer list further comprises receiving the peer list that includes connectivity information of a streaming source that originated the streaming content.

4. The method of claim 2, further comprising:

generating the peer list including connectivity information of a streaming source that originated the streaming content; and

evaluating a number of clients in the peer-to-peer network in response to receiving a request for the peer list.

5. The method of claim 4, further comprising removing the connectivity information of the streaming source if the number of clients equals or exceeds a threshold.

6. The method of claim 1, further comprising transmitting the streaming content encapsulated in the one or more data blocks to a second client of the peer-to-peer network.

7. The method of claim 6, further comprising:

storing, by the second client of the peer-to-peer network, the streaming content encapsulated in the one or more data blocks;

extracting, by the second client of the peer-to-peer network, the streaming content from the one or more data blocks;

assembling, by the second client of the peer-to-peer network, the streaming content into the native format of the streaming content;

storing, by the second client of the peer-to-peer network, the streaming content in the native format.

8. The method of claim 1, further comprising:

establishing a connection with a client external to the peer-to-peer network; and

conveying the streaming content in the native format to the client external to the peer-to-peer network.

9. A computer-readable medium having computer-executable instructions for execution by a processing system, the computer-executable instructions for replicating streaming content in a peer-to-peer network, comprising:

instructions that receive encapsulated streaming content in one or more data blocks formatted according to a transport format of the peer-to-peer network;

instructions that extract the streaming content from the one or more data blocks;

instructions that assemble the streaming content into a native format of the streaming content;

instructions that store the streaming content in the native format; and

instructions that convey at least a portion of the streaming content in the native format to a second client external to the peer-to-peer network.

10. The computer-readable medium of claim 9, further comprising instructions that receive a peer list of connectivity information of one or more nodes in the peer-to-peer network, wherein the streaming content is received from at least one of the one or more nodes.

11. The computer-readable medium of claim 10, wherein the peer list includes connectivity information of a streaming source that originated the streaming content.

12. The computer-readable medium of claim 10, further comprising:

instructions that generate the peer list including connectivity information of a streaming source that originated the streaming content; and

instructions that evaluate a number of clients in the peer-to-peer network in response to receiving a request for the peer list.

13. The computer-readable medium of claim 12, further comprising instructions that remove the connectivity information of the streaming source if the number of clients equals or exceeds a threshold.

14. The computer-readable medium of claim 9, further comprising instructions that transmit the encapsulated streaming content in the one or more data blocks to a second client of the peer-to-peer network.

15. The computer-readable medium of claim 14, further comprising:

instructions executed by the second client of the peer-to-peer network that store the encapsulated streaming content in the one or more data blocks;

instructions executed by the second client of the peer-to-peer network that extract the streaming content from the one or more data blocks;

instructions executed by the second client of the peer-to-peer network that assemble the streaming content into the native format of the streaming content;

instructions executed by the second client of the peer-to-peer network that store the streaming content in the native format.

16. The computer-readable medium of claim 9, further comprising:

instructions that establish a connection with a client external to the peer-to-peer network; and

instructions that convey the streaming content in the native format to the client external to the peer-to-peer network.

17. A data processing system for replicating streaming content in a peer-to-peer network, comprising:

a memory that contains a transport module and a reconstruction module as sets of instructions;

a network adapter that interfaces with a communications medium; and

a processing unit that, responsive to execution of one or more of the sets of instructions, receives encapsulated streaming content formatted according to a transport format of the peer-to-peer network over the communications medium, reconstructs the streaming content in a native streaming format, and that conveys the streaming content in the native streaming format to a client that is external to the peer-to-peer network.

18. The system of claim 17, wherein the processing unit reconstructs the streaming content by extracting the streaming content from the encapsulated streaming content and assembling the streaming content into a data structure compliant with the native format.

19. The system of claim 18, wherein the processing unit stores the data structure.

20. The system of claim 18, wherein the processing unit stores the encapsulated streaming content.

21. The system of claim 17, wherein the processing unit receives a peer list of connectivity information of one or more nodes in the peer-to-peer network, and wherein the encapsulated streaming content is received from at least one of the one or more nodes.

22. The system of claim 17, wherein the processing unit establishes a connection over the communication medium with a client in the peer-to-peer network and conveys at least a portion of the encapsulated streaming content to the client.

23. The system of claim 17, wherein the processing unit establishes a connection with a client external to the peer-to-peer network and conveys the streaming content in the native streaming format to the client external to the peer-to-peer network.
