AbstractCache plays an important role in most calculation, match occasion. It can improve access efficiency, reform system performance, and so
on. In addition to the use in processor, cache can be used in Web access and storage system to increase the access rate. This paper analyses the
replacement algorithm used in processor and Web Cache, considers the character of network attached optical jukebox and brings forward a new
replacement algorithm. The algorithm combines the specialty of LFU algorithm and MQ algorithm to improve the hit-rate in cache. It shows the
replacement algorithm has a close relation with access model.
