APPARATUS AND METHOD FOR MANAGING CACHE IN CACHE DISTRIBUTED ENVIRONMENT

摘要

Disclosed is a cache management apparatus based on a distributed environment. The cache management apparatus includes a local cache that stores a preset amount of first cache data; a cache distribution state view configured to have the record of location and state information about the first cache data stored in the local cash and second cache data stored in the other nodes; a synchronization processing unit configured to synchronize the location and state information about the first and second cache data. Further, the cache management apparatus includes a distributed cache calculation controlling unit, upon receipt of a request for particular cache data from any application, configured to identify the location of the requested particular cache data and to retrieve the requested cache data from the other nodes or the local cache to provide it to the application.
