Abstract

A method and apparatus for peer-to-peer services have been described.

Claims

1. A method comprising:

receiving a request for a file, wherein the request for the file is received from a first client of a plurality of clients within a network;

determining a first source for a latest version of the file, the first source representing a nearest source including a second client of the plurality of clients, wherein the determining of the first source includes referencing a prioritized list of clients of the plurality of clients, each client of the prioritized list of clients having the file;

communicating the first source having the file to the first client;

directing the first client to the first source to obtain the file; and

redirecting the first client to a second source away from the first source, if the second source contains a version of the file that is latest than the latest version of the file at the first source, the second source including a third client of the plurality of clients.

2. The method of claim 1, further comprising transferring the file from the nearest source to the first client.

3. The method of claim 2, wherein the transfer includes a peer-to-peer transfer.

4. The method of claim 1, further comprising maintaining the prioritized list of clients at a directory server.

5. The method of claim 1, wherein the determining of the nearest source comprises seeking the nearest source having a shortest transfer time for the file from the nearest source to the first client.

6. A system comprising:

a directory server having a bi-directional communications port, a directory server output, and a directory server input, the bi-directional communications port coupled to receive a request for a file, wherein the request for the file is received from a first client of a plurality of clients within a network; and

a nearest data locating engine having an engine input, and an engine output, the engine input to receive the directory server output, and the engine output to receive the directory saver input, the nearest data locating engine to determine a first source for a latest version of the file, the first source representing a nearest source including a second client of the plurality of clients, wherein the determining of the first source includes referencing a prioritized list of clients of the plurality of clients, each client of the prioritized list of clients having the file, wherein the nearest data locating engine to communicate the first source having the file to the first client, direct the first client to the first source to obtain the file, and redirect the first client to a second source away from the first source, if the second source contains a version of the file that is latest than the latest version of the file at the first source, the second source including a third client of the plurality of clients.

7. The system of claim 6, further comprising a router having a first communications port, and a second communications port, the first communications port coupled to receive communications from the directory server, and the second communications port coupled to receive communications from the network.

8. A machine-readable storage medium comprising instructions which, when executed, cause a machine to:

receive a request for a file, wherein the request for the file is received from a first client of a plurality of clients within a network;

determine a first source for a latest version of the file, the first source representing a nearest source including a second client of the plurality of clients, wherein the determining of the first source includes referencing a prioritized list of clients of the plurality of clients, each client of the prioritized list of clients having the file;

communicate the first source having the file to the first client;

direct the first client to the first source to obtain the file; and

redirecting the first client to a second source away from the first source, if the second source contains a version of the file that is latest than the latest version of the file at the first source, the second source including a third client of the plurality of clients.

9. The machine-readable storage medium of claim 8, wherein the instructions which when executed, further cause the machine to transfer the file from the nearest source to the first client.

10. The machine-readable storage medium of claim 9, wherein the transfer includes a peer-to-peer transfer.

11. The machine-readable storage medium of claim 8, wherein the instructions which when executed, further cause the machine to maintain the prioritized list of clients at a directory server.

12. The machine-readable storage medium of claim 8, wherein the determining of the nearest source comprises seeking the nearest source having a shortest transfer time for the file from the nearest source to the first client.
