PRIORITIZED DUAL CACHING METHOD AND APPARATUS

摘要

Provided are a prioritized dual caching method and apparatus. The dual caching apparatus includes a content cache unit configured to store a content cache separated into a first (premium) cache and a second (general) cache, a pointer storage unit configured to store a pointer for variably separating the first and second caches, a threshold value storage unit configured to store a first threshold value and a second threshold value that is less than the first threshold value, and a cache policy execution unit configured to receive a request for content, manage a request count value for the content, and execute a cache policy based on results of comparing the request count value to the first threshold value and the second threshold value and whether there is requested content in the content cache.

1. A dual caching method using a content cache separated into a first (premium) cache and a second (general) cache, comprising:
receiving a request for content; performing a counting operation of incrementing a request count value for requested content; making a cache hit determination by determining whether there is the requested content in the content cache; and executing a first policy of determining whether to delete the requested content from the content cache by comparing the request count value to a first threshold value when there is the requested content in the content cache and determining one of the first and second caches in which the requested content is positioned by comparing the request count value to a predetermined second threshold value, which is less than the first threshold value.
