ABSTRACT:
A method for managing cache elements in an environment based on Common Information Model is described. Cache elements in the cache are associated with a time attribute and historical data. Cache elements having a time attribute lying in a certain range are polled for from the server and updated at predetermined time points. A new time attribute is calculated for each cache element based on its historical data and this new time attribute assists in adapting the polling frequency for the cache element to its importance and change characteristics. Asynchronous notifications from the server preempt the polling based on the time attribute for a cache element and instead, polling for the cache element is based on the asynchronous notification. A system for cache management includes a client and a server, the client having a cache that is managed based on each cache element's importance and change characteristics.
