Abstract:

To enhance the performance of data retrieval, the authors used cache approach, designed rational cache structure and presented a distributed file caching algorithm based on aging algorithm. In the concrete realization part of the cache, the LRU (least recently used) algorithm was used, which is a excellent approximation algorithm: the aging algorithm, which was transferred a page replacement algorithm into a file cache replacement algorithm, and in the process, it inherited the advantages of the aging algorithm. The evaluation results show that the improved approach is effective.

Key words: caching algorithm, aging algorithm, replacement algorithm
