Abstract

Peer-to-peer services. Routers monitor network traffic and data to create a list determining which server or peer device has the best path to data sets. Traffic data may then be sent to a server or a receiving device with instructions to follow the best path.

Claims

1. A method comprising:

receiving a request for a data file from a requesting device;

determining data sources having the data file;

creating a prioritized list of best paths to the data sources;

selecting a data source having a best path to the requesting device;

establishing a direct peer-to-peer communication between the data source and the requesting device, wherein the establishing of the direct peer-to-peer communication includes identifying the data source to the requesting device; and

directing the requesting device to the data source for the requesting the device to obtain the data file from the data source via the best path, the directing of the requesting device to the data source including directing traffic from a first network to a second network such that the second network provides a proxy service for the first network, wherein the directing of the requesting device to the data source based on a predetermined time period having an expiration timeout, wherein the requesting device is directed to the data source after the predetermined time period has reached, wherein the predetermined time period is tailored according to content of the data file.

2. The method of claim 1, wherein the creating of the prioritized list comprises considering one or more of a physical location of the requesting device, physical locations of the data sources, a network to which the requesting device is attached, overall bandwidth of the network, available bandwidth of the network, time expiration of the data file at the data source, size of the data file at the data source, and time to transfer the data file from the data source to the requesting device.

3. The method of claim 1, further comprising maintaining the prioritized list, and monitoring the prioritized list to facilitate the selection of the data source having the data file.

10. The method of claim 1, wherein the first network includes a Wide Area Network (WAN), and the second network includes a Local Area Network (LAN).

4. A system comprising:

a storage medium;

a server coupled to the storage medium, the server including a directory server,

the directory server to receive a request for a data file from a requesting device;

determine data sources having the data file;

create a prioritized list of best paths to the data sources; and

select a data source having a best path to the requesting device;

establish a direct peer-to-peer communication between the data source and the requesting device, wherein the establishing of the direct peer-to-peer communication includes identifying the data source to the requesting device; and

direct the requesting device to the data source for the requesting the device to obtain the data file from the data source via the best path, the directing of the requesting device to the data source including directing traffic from a first network to a second network such that the second network provides a proxy service for the first network,

wherein the directing of the requesting device to the data source based on a predetermined time period having an expiration timeout, wherein the requesting device is directed to the data source after the predetermined time period has reached, wherein the predetermined time period is tailored according to content of the data file; and

the requesting device coupled to the server, the requesting device to obtain the data file from the data source via the best path.

5. The system of claim 4, wherein the server is further to maintain the prioritized list, and monitor the prioritized list to facilitate the selection of the data source having the data file.

6. The system of claim 5, wherein the server is further to considering one or more of a physical location of the requesting device, physical locations of the data sources, a network to which the requesting device is attached, overall bandwidth of a network, available bandwidth of the network, time expiration of the data file at the data source, size of the data file at the data source, and time to transfer the data file from the data source to the requesting device.

11. The system of claim 4, wherein the first network includes a Wide Area Network (WAN), and the second network includes a Local Area Network (LAN).

7. A tangible machine-readable storage medium having instructions which, when executed, cause a machine to:

receive a request for a data file from a requesting device;

determine data sources having the data file;

create a prioritized list of best paths to the data sources;

select a data source having a best path to the requesting device;

establish a direct peer-to-peer communication between the data source and the requesting device, wherein the establishing of the direct peer-to-peer communication includes identifying the data source to the requesting device; and

direct the requesting device to the data source for the requesting the device to obtain the data file from the data source via the best path, the directing of the requesting device to the data source including directing traffic from a first network to a second network such that the second network provides a proxy service for the first network, wherein the directing of the requesting device to the data source based on a predetermined time period having an expiration timeout, wherein the requesting device is directed to the data source after the predetermined time period has reached, wherein the predetermined time period is tailored according to content of the data file.

8. The tangible machine-readable storage medium of claim 7, wherein the instructions when executed, further cause the machine to consider one or more of a physical location of the requesting device, physical locations of the data sources, a network to which the requesting device is attached, overall bandwidth of the network, available bandwidth of the network, time expiration of the data file at the data source, size of the data file at the data source, and time to transfer the data file from the data source.

9. The tangible machine-readable storage medium of claim 7, wherein the instructions when executed, further cause the machine to maintain the prioritized list, and maintain the prioritized list, and monitor the prioritized list to facilitate the selection of the data source having the data file.

12. The tangible machine readable storage medium of claim 7, wherein the first network includes a Wide Area Network (WAN), and the second network includes a Local Area Network (LAN).
