Method and system for dynamic distributed data caching
A method and system for dynamic distributed data caching is presented. The method includes providing a cache community comprising at least one peer. Each peer has an associated first content portion indicating content to be cached by the respective peer. A client may be allowed to join the cache community. A peer list associated with the cache community is updated to include the client. The peer list indicates the peers in the cache community. A respective second content portion is associated with each peer based on the addition of the client.
1. A method for dynamic distributed data caching, comprising:
generating a content request for requested content at a first peer in a cache community;
determining a second peer associated with the requested content, the second peer being associated with the cache community; and
retrieving, by the first peer, the requested content from the second peer;
wherein determining the second peer includes:
generating, by a cache portion associated with the first peer, a location request;
communicating the location request to a master associated with the cache community; and
receiving a location response from the master, the location response indicating the second peer.
2. The method of claim 1 , further comprising:
retrieving, by the second peer, the requested content from an origin server when the requested content is unavailable at the second peer; and
storing the requested content at the second peer.
3. The method of claim 2 , wherein the requested content is unavailable when the requested content has been expired.
4. The method of claim 2 , wherein the requested content is unavailable when the requested content is not stored at the second peer.
5. The method of claim 1 , wherein the cache portion includes a software application.
6. The method of claim 1 , further comprising:
forwarding the content request to the second peer.
7. The method of claim 1 , wherein the content request includes a hypertext transport protocol request.
8. The method of claim 1 , wherein the content includes a web page.
9. The method of claim 1 , wherein the first and second peers respectively include a member of the cache community.
10. A computer readable storage medium including code for dynamic distributed data caching, the code operable to:
generate a content request for requested content at a first peer in a cache community;
determine a second peer associated with the requested content, the second peer being associated with the cache community; and
retrieve, by the first peer, the requested content from the second peer;
wherein the code operable to determine the second peer is further operable to:
generate, by a cache portion associated with the first peer, a location request;
communicate the location request to a master associated with the cache community ; and
receive a location response from the master, the location response indicating the second peer.
11. The computer readable storage medium of claim 10 , wherein the code is operable to:
retrieve, by the second peer, the requested content from an origin server when the requested content is unavailable at the second peer; and
store the requested content at the second peer.
12. The computer readable storage medium of claim 11 , wherein the requested content is unavailable when the requested content has been expired.
13. The computer readable storage medium of claim 11 , wherein the requested content is unavailable when the requested content is not stored at the second peer.
14. The computer readable storage medium of claim 10 , wherein the cache portion includes a software application.
15. The computer readable storage medium of claim 10 , wherein the code is operable to forward the content request to the second peer.
16. The computer readable storage medium of claim 10 , wherein the content request includes a hypertext transport protocol request.
17. The computer readable storage medium of claim 10 , wherein the content includes a web page.
18. The computer readable storage medium of claim 10 , wherein the first and second peers respectively include a member of the cache community.
19. A system for dynamic distributed data caching comprising:
means for generating a content request for requested content at a first peer in a cache community;
means for determining a second peer associated with the requested content, the second peer being associated with the cache community; and
means for retrieving, by the first peer, the requested content from the second peer;
wherein the means for determining the second peer includes:
means for generating, by a cache portion associated with the first peer, a location request;
means for communicating the location request to a master associated with the cache community; and
means for receiving a location response from the master, the location response indicating the second peer.
20. The system of claim 19 , further comprising:
retrieving, by the second peer, the requested content from an origin server when the requested content is unavailable at the second peer; and
storing the requested content at the second peer.
21. The system of claim 20 , wherein the requested content is unavailable when the requested content has been expired.
22. The system of claim 20 , wherein the requested content is unavailable when the requested content is not stored at the second peer.
23. The system of claim 19 , wherein the cache portion includes a software application.
24. The system of claim 19 , further comprising:
forwarding the content request to the second peer.
25. The system of claim 19 , wherein the content request includes a hypertext transport protocol request.
26. The system of claim 19 , wherein the content includes a web page.
27. The system of claim 19 , wherein the first and second peers respectively includes a member of the cache community.
