Abstract

IETF has developed two architectures for the Internet, Integrated Services (IntServ) and Differentiated Services (DiffServ), which should enable QoS based handling of data flows in IP networks. This paper presents a number of measurements which were carried out in order to determine some performance differences between these QoS mechanisms, as well as some characteristics about their joint use. The results show that in some cases the flow aggregation model, i.e. DiffServ, can provide the same or even better QoS than the reservation based model, i.e. IntServ.
