Abstract

Previously, QoS queueing schedule algorithms for Web servers and QoS Web caching were studied individually. In this paper, we examine the combination of both algorithms aimed at an optimal QoS solution for both clients and the server. By integrating one of the three schedule rules: best effort, DiffServ (differentiated services) and WSPT (weighted shortest processing time), with one of the two caching replacement algorithms: LRU (least recently used) and LLP (least level property) respectively, we develop six simulation models to compare their performance with the three metrics for QoS measures: timeliness, precision and accuracy
