System and method for the location of caches
A method for selecting a preferred cache for the download of digital data from a plurality of caches is disclosed. The method comprises the steps of requesting an address of the preferred cache and selecting the preferred cache from the plurality of caches. The selection of the preferred cache is derived from a location identifier of a client requesting the download of the digital data.
1. A method comprising the steps of:
sending, from a client to a server, a request for an address of a preferred cache among a plurality of caches in a peer-to-peer network, the request requesting a download of digital data;
receiving a handle, wherein a proxy intercepts the handle and the proxy modifies the handle to insert the address of the preferred cache; and
selecting the preferred cache from the plurality of caches, the selection being derived from a network address of the client.
2. The method of claim 1 , wherein the network address of the client is the IP address of the client.
3. The method of claim 2 , wherein selecting the preferred cache is further based upon availability of the plurality of caches, network costs, location of data and/or network tasks.
4. The method of claim 1 , wherein the server is a location server.
5. The method of claim 1 , wherein the server is a tracker.
6. The method of claim 1 , further comprising transferring the address of the preferred cache to the client.
7. The method of claim 6 , wherein the address of the preferred cache is transferred by a name server.
8. The method of claim 7 , wherein the name server is a DNS server.
9. The method of claim 1 , further comprising passing the handle to a name server.
10. The method of claim 1 , wherein the handle comprises a location string.
11. The method of claim 1 , wherein the handle comprises a publisher string.
12. The method of claim 1 , wherein the handle comprises a protocol string.
13. The method of claim 1 , wherein selecting the preferred cache is based on at least part of the handle.
14. The method of claim 1 , wherein selecting the preferred cache from the plurality of caches comprises using the network address of the client to identify a location of the client relative to one or more of the plurality of caches.
15. A server with a processor operably coupled to a memory, wherein:
the processor is operative for selecting a preferred cache for the download of digital data from a plurality of caches in a peer-to-peer network;
the selection being derived from a network address of a client requesting the address of the preferred cache for a download of the digital data wherein the server returns a handle to the client, the handle being intercepted by a proxy and the proxy modifying the handle to insert an address of the preferred cache.
16. The server of claim 15 , wherein the network address of the client is the IP address of the client.
17. The server of claim 15 , wherein the server is connected to a database.
18. The server of claim 15 , wherein the server further comprises a name server for transferring an address of the preferred cache to the client.
19. The server of claim 18 , wherein the name server is a DNS server.
20. The server of claim 18 , wherein the name server is connected to the database.
21. The server of claim 15 , wherein the server is integrated in a tracker for tracking peer-to peer information.
22. The server of claim 15 , wherein the server is integrated in a proxy for tracker communications.
