Abstract

Differentiated services (DiffServ) have been recently adopted in Web services. In the Web caching field, researchers have proposed to realize DiffServ at original Web servers, cache servers, or at the client side. We propose to support differentiation at edge routers. An edge router can perform request classification, and assign the per-hop behavior (PHB) of the classified requests. In this paper, we present our DiffServ in switching-based Web caching system (DSW). DSW provides different types of service to three classes of requests, namely, streaming-object class (SC), real-time assured class (RC) and best-effort class (BC). In DSW, it is assumed that SC has higher priority than RC, which in turn has higher priority than BC. A comprehensive simulation is used to study the performance of DSW.
