Method and System for Dynamic Distributed Data Caching

摘要

A method and system for dynamic distributed data caching is presented. The system includes one or more peer members and a master member. The master member and the one or more peer members form cache community for data storage. The master member is operable to select one of the one or more peer members to become a new master member. The master member is operable to update a peer list for the cache community by removing itself from the peer list. The master member is operable to send a nominate master message and an updated peer list to a peer member selected by the master member to become the new master member.

1. A client system in a cache community for community data caching, comprising:
a storage space including a dedicated cache portion operable to cache content in the cache community; a cache module operable to manage content cached in the cache portion of the storage space, the cache module including a location table operable to identify locations of caches within the cached community where content should be cached; a processor operable to generate a request for content, the cache module operable to intercept and process the request, determine where the content should be located, query a remote cache module for the content if the content should be located at the remote cache module, and deliver requested content from any cache in the cache community when cached or from an origin server when not cached; wherein the cache module is configurable to limit consumption of resources in the client system.
