Abstract

A method and computer-readable medium for downloading content in a peer-to-peer network is provided. A client detects a download event associated with an identifier of a file and submits a query that includes an identifier of a file to an indexing server. The client receives a peer list including connectivity information of a peer node that has stored at least a portion of content of the file. The client then connects wit the peer node, and downloads the portion from the peer node.

Claims

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

detecting a download event associated with an identifier of a file;

submitting a query that includes the identifier to an indexing server;

receiving a peer list including connectivity information of a peer node that has stored at least a portion of content of the file;

connecting with the peer node; and

downloading the portion from the peer node.

2. The method of claim 1, wherein receiving the peer list further comprises receiving the peer list including connectivity information of one or more file servers external to the peer-to-peer network.

3. The method of claim 2, further comprising:

connecting with the file server; and

downloading portions of the file from at least one of the one or more file servers.

4. The method of claim 1, further comprising generating the query in response to the download event being detected.

5. The method of claim 1, wherein detecting the download event comprises detecting a click event on a hypertext link, and wherein the identifier is a uniform resource locator associated with the hypertext link.

6. The method of claim 1, wherein the identifier is information comprising a combination of a uniform resource locator, a file size and a last modification time of the file.

7. The method of claim 6, wherein the identifier is a variant format of the information.

8. The method of claim 1, wherein detecting the download event comprises detecting entry of a uniform resource locator in a browser application.

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

instructions that detect a download event associated with an identifier of a file;

instructions that submit a query that includes an identifier of a file to an indexing server;

instructions that receive a peer list including connectivity information of at least one network entity that has stored at least a portion of content of the file;

instructions that connect with the peer node; and

instructions that download the portion from the peer node.

10. The computer-readable medium of claim 9, wherein the peer list includes connectivity information of one or more file servers external to the peer-to-peer network.

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

instructions that connect with the file server; and

instructions that download a second portion of the file from the file server.

12. The computer-readable medium of claim 9, further comprising instructions that generate the query in response to the download event being detected.

13. The computer-readable medium of claim 9, wherein the download event comprises a click event on a hypertext link, and wherein the identifier is a uniform resource locator associated with the hypertext link.

14. The computer-readable medium of claim 9, wherein the identifier comprises a combination of a uniform resource locator, a file size and a last modification time of the file.

15. The computer-readable medium of claim 14, wherein the information is a variant format of the combination.

16. The computer-readable medium of claim 9, wherein the download event comprises entry of a uniform resource locator in a browser application.

17. A device for downloading content in a network system, comprising:

a network interface;

a memory containing a browser implemented as a set of instructions; and

a processing unit that, in response to execution of the set of instructions, detects a download event, submits a query that includes an identifier of a file to an indexing server over the network interface, and determines whether a node in a peer-to-peer network has at least a first portion of the file.

18. The device of claim 17, wherein the processing unit connects with a file server that has the file stored and downloads a portion of the file from the file server.

19. The device of claim 17, wherein the identifier is a uniform resource locator, and wherein the file is located at the address specified by the uniform resource locator.

20. The device of claim 17, wherein the identifier comprises a combination of a uniform resource locator, a file size and a last modification time of the file.

21. The device of claim 17, wherein the identifier is a variant format of the combination.

22. The device of claim 17, wherein the identifier is a uniform resource locator and wherein the download event is a click event on a hypertext link associated with the uniform resource locator displayed in the browser.

23. The device of claim 17, wherein the identifier is a uniform resource locator and wherein the download event is an entry of the uniform resource locator in the browser.

24. A device adapted to download content in a network system, comprising:

means for detecting a download event associated with an identifier of a file;

means for submitting a query that includes the identifier to an indexing server;

means for receiving a peer list including connectivity information of a peer node that has stored at least a portion of content of the file;

means for connecting with the peer node; and

means for downloading the portion from the peer node
