We consider the least-recently-used (LRU) cache replacement rule with a Zipf-type page request distribution and investigate the asymptotic property of the fault probability according to the increase of cache size. We first derive the asymptotics of the fault probability for the i.i.d. request model and then extend it to a general dependent request model, where our result shows that, under some ...
