METHOD FOR DETERMINING DATA IN CACHE MEMORY OF CLOUD STORAGE ARCHITECTURE AND CLOUD STORAGE SYSTEM USING THE SAME

摘要

A method for determining data in cache memory of a cloud storage architecture and a cloud storage system using the method are disclosed. The method includes the steps of: A. recording transactions from cache memory of a cloud storage during a period of time in the past, wherein each transaction comprises a time of recording, or a time of recording and cached data been accessed during the period of time in the past; B. assigning a specific time in the future; C. calculating a time-associated confidence for every cached data from the transactions based on a reference time; D. ranking the time-associated confidences; and E. providing the cached data with higher time-associated confidence in the catch memory, and removing the cached data in the cache memory with lower time-associated confidence when the cache memory is full before the specific time in the future.
