Abstract

The present invention relates to methods, apparatus, and systems for providing peer-to-peer network acceleration. The system includes content servers and clients. Each of the clients is capable of functioning as a proxy server. A client generates a request for content, and the requesting client determines which of the content servers contains the requested content. The requesting client then determines that one of the clients is in a position to retrieve the requested content on the content server at lower latency than the requesting client. The client then functions as a proxy server for the requesting client, and the requesting client receives the requested content from the client acting as a proxy server.

Claims

1. A system for providing peer-to-peer network acceleration, the system comprising:

a plurality of clients in communication together and in communication with at least one content server, wherein each of the plurality of clients is capable of functioning as a proxy server by receiving a peer-to-peer request for content that identifies an associated content server, and by communicating the peer-to-peer request for content to the associated content server;

wherein at least one of the plurality of clients generates a request for content from a content server and the request is part of a chatty communication with a plurality of round trips to complete a response to the request;

wherein the requesting client determines that at least one of the plurality of clients is in a position to retrieve the requested content on the content server at lower latency than the requesting client;

wherein the one of the plurality of clients functions as a proxy server for the requesting client by receiving the request for content from the content server, requesting the content from the content server, and communicating the content as received from the content server to the at least one of the plurality of clients that generates the request for content; and

wherein the requesting client is configured to receive, from the content server via the at least one of the plurality of clients functioning as a proxy server for the requesting client, the requested content.

2. A system for providing peer-to-peer network acceleration as in claim 1, wherein the plurality of clients each include a proxy client running locally on the client machine.

3. A system for providing peer-to-peer network acceleration as in claim 1, wherein the proxy server comprises an acceleration module.

4. A system for providing peer-to-peer network acceleration as in claim 3, wherein the acceleration module is configured to decrease network latency and round trips.

5. A system for providing peer-to-peer network acceleration as in claim 1, wherein the plurality of clients and the plurality of content servers are in communication via a satellite network.

6. A system for providing peer-to-peer network acceleration as in claim 1, wherein the plurality of content servers comprise at least one or more of the following:

a mail server, a web server, and a file server.

7. A system for providing peer-to-peer network acceleration as in claim 1, wherein the requesting client is at a first location.

8. A system for providing peer-to-peer network acceleration as in claim 7, wherein the one of the plurality of clients functioning as the proxy server for the requesting client and the content server with the lower latency are at a second location.

9. A system for providing peer-to-peer network acceleration as in claim 8, wherein the first location and the second location are remotely located from each other.

10. A system for providing peer-to-peer network acceleration as in claim 8, wherein either the first location or the second location is a data center.

18. The method of claim 1 further comprising:

receiving, at the second client, the request from the first client for the content;

receiving, at the second client, the content as part of the communication with a plurality of round trips between the second client and the content server; and

communicating, from the second client to the first client, the content as part of a single transmission from the second client to the first client.

19. The method of claim 1 further comprising:

receiving, at the second client, the request from the first client for the content;

receiving, at the second client, the content as part of a communication with a plurality of round trips between the second client and the content server; and

communicating, from the second client to the first client, the content using a reduced number of round trips than is used during communication of the content from the content server to the second client.

20. The method of claim 1 wherein the content comprises a web page prefetch or a download file.

11. A method of providing peer-to-peer network acceleration, the method comprising:

generating, at a client system, a request for content from a content server, wherein the client system is one of a plurality of client systems and each of the plurality of client systems is capable of functioning as a proxy server by receiving a peer-to-peer request for content that identifies an associated content server, and by communicating the peer-to-peer request for content to the associated content server;

determining that at least one of the plurality of clients is in a position to retrieve the requested content on the content server at lower latency than the requesting client;

selecting at least one of the plurality of client systems to function as a proxy server for the requesting client;

communicating the request for content to the selected at least one of the plurality of clients, wherein the request identifies the content server that is separate from the selected at least one of the plurality of clients and the request is part of a communication with a plurality of round trips between the content server and the selected at least one of the plurality of clients to complete a response to the request; and

receiving, from the content server via the at least one of the plurality of clients functioning as a proxy server for the requesting client, the requested content.

12. A method of providing peer-to-peer network acceleration as in claim 11, wherein the plurality of clients each include a proxy client running locally on the client machine.

13. A method of providing peer-to-peer network acceleration as in claim 11, wherein the proxy server comprises an acceleration module.

14. A method of providing peer-to-peer network acceleration as in claim 13, wherein the acceleration module is configured to decrease network latency and round trips.

15. A method of providing peer-to-peer network acceleration as in claim 11, wherein the plurality of clients and the server are in communication via a satellite network.

16. A method of providing peer-to-peer network acceleration as in claim 11, wherein the plurality of content servers comprise at least one or more of the following:

a mail server, a web server, and a file server.

17. A method of providing peer-to-peer network acceleration, the method comprising:

generating, at a first client system, a request for content from a content server, wherein;

the first client system is one of a plurality of client systems;

communication links between each of the plurality of client systems are high latency links;

a first link from the first client system to the content server comprises a high latency link;

the request is part of a chatty communication with a plurality of round trips to complete a response to the request; and

each of the plurality of client systems is capable of requesting content on behalf of each of the other client systems;

determining, in response to the request, that at least one of the plurality of clients is in a position to retrieve the content from the content server at lower latency than the first client;

selecting a second client of the at least one of the plurality of client systems that is in a position to retrieve the content from the content server at lower latency than the first client to request the content from the content server;

communicating the request from the first client to the second client; and

receiving at the first client system, from the content server via the selected at least one of the plurality of clients, the content.
