Abstract

A method and system for accelerating downloading and displaying of content in web pages in a peer-to-peer network is provided. A peer-to-peer network client captures a download request from a web browser, and submits a query that includes an identifier of the file to an indexing server. The peer-to-peer network client receives a peer list including connectivity information of a peer node that has stored at least a portion of the file content. The peer-to-peer network client then connects with the peer node, and downloads the portion from the peer node. The peer-to-peer client conveys the downloaded portion to the web browser.

Claims

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

capturing a download request for a file from a web browser;

determining whether content of the file is stored in the peer-to-peer network;

responsive to determining at least a portion of the content is stored in the peer-to-peer network, connecting with a node of the peer-to-peer network; and

downloading the portion from the node.

2. The method of claim 1, further comprising conveying the portion to the web browser responsive to downloading the portion.

3. The method of claim 1, wherein capturing further comprises registering a processing method of a protocol in an instance of a web browser.

4. The method of claim 1, wherein capturing further comprises adding a registration item for a protocol to an operating system.

5. The method of claim 1, wherein capturing further comprises setting up a proxy for the web browser.

6. The method of claim 1, further comprising:

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

receiving a peer list including connectivity information of the peer node.

7. The method of claim 6, 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.

8. The method of claim 7, further comprising:

connecting with at least one or more of the file servers; and

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

9. The method of claim 6, wherein submitting a query that includes an identifier further comprises submitting a query that includes the identifier that comprises at least one of a uniform resource locator and an identifier derived from the uniform resource locator.

10. The method of claim 9, wherein the identifier comprises at least one of a combination of a uniform resource locator, a file size and a last modification time and a derivation of the combination, wherein the file size and the last modification time are retrieved from a file server.

11. The method of claim 1, wherein downloading further comprises sequentially downloaded a plurality of blocks that comprise the portion.

12. The method of claim 11, wherein each of the plurality of blocks respectively comprises a randomized portion of the file.

13. The method of claim 1, further comprising:

saving the portion to a file cache; and

reporting the saved portion to an indexing server.

14. The method of claim 13, further comprising:

waiting for a query from a second peer node; and

returning data related to the query to the second peer node.

15. The method of claim 1, further comprising downloading a second portion of the file from a source server of the file, wherein the source server is external to the peer-to-peer network.

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

instructions of a peer-to-peer network client application that capture a download request for a file from a web browser;

instructions of the application that determine whether content of the file is stored in the peer-to-peer network;

instructions of the application that connect with a node of the peer-to-peer network in response to a determination being made that at least a portion of the content is stored in the peer-to-peer network; and

instructions of the application that download the portion from the node.

17. The computer-readable medium of claim 16, further comprising instructions that convey the portion to the web browser responsive to the portion being downloaded.

18. The computer-readable medium of claim 16, wherein the instructions that download the portion submit a query that includes an identifier of the file to an indexing server and receive a peer list including connectivity information of the peer node.

19. The computer-readable medium of claim 18, wherein the peer list includes connectivity information of one or more file servers external to the peer-to-peer network.

20. The computer-readable medium of claim 19, further comprising:

instructions that connect with at least one or more of the file servers; and

instructions that download portions of the file from at least one of the one or more file servers.

21. The computer-readable medium of claim 18, wherein the identifier comprises at least one of a uniform resource locator and an identifier derived from the uniform resource locator.

22. The computer-readable medium of claim 16, further comprising instructions that download a second portion of the file from a source server of the file, wherein the source server is external to the peer-to-peer network.

23. A peer-to-peer network for delivering content to peer clients, comprising, a first peer node that maintains a portion of a file;

and

a second peer node that runs a web browser that receives a request for the file and a peer client application that captures the file request, wherein the peer client application connects with the first peer node, downloads the portion from the first peer node, and conveys the portion to the web browser.

24. The network of claim 23, further comprising an indexing server that maintains records of peer nodes registered in the peer-to-peer network and identifiers of content maintained by respective peer nodes.

25. The network of claim 24, wherein the peer client application generates a query including an identifier of the file, conveys the query to the indexing server, and receives a peer list from the indexing server that includes respective connectivity information of peer nodes of the network that maintain at least a portion of the file.

26. The network of claim 25, wherein the peer list includes connectivity information of a file server that maintains the file, wherein the file server is external to the peer-to-peer network.

27. The network of claim 25, wherein the identifier comprises one of a uniform resource locator of the file and a value derived from the uniform resource locator.

28. The network of claim 25, wherein the identifier is derived from the uniform resource locator, a file size and a file last modification time.

29. The network of claim 23, wherein the second peer node saves the portion of the file to a storage media and reports information of the saved portion to an indexing server.
