Average Least Frequency Used (ALFUR) cache replacement technology USING intelligent agents

Abstract

Web caching is an important technique to scale the internet. To increase the speed of browsing, Replacement strategies are used. Least Frequency Used (LFU) replacement strategy is one of these web cache replacement strategies. The lack of LFU strategy is that it ignores download latency and size of object and may store obsolete web object indefinitely. A new proposed replacement strategy based on LFU replacement which named Average Least Frequency Used Removal (ALFUR) has been highlighted in this paper. ALFUR can be considered as enhancement of LFU since it overcome the lacks of LFU.
