Abstract :
In this paper, we propose a new architecture for guaranteeing the multiple Quality of Services (QoSs) in Differentiated Service Internet. We take into account the IETF´s Differentiated Service (DiffServ) architecture as well as the QoS requirements of each user application. The main focus lies in the modeling and performance evaluation of the prioritized packet service scheme in the core router which supports weighted priority services in the packet with three service classes defined in IETF: EF (Expedited forwarding), AF (Assured forwarding) and DF (Default forwarding) PHB (Per Hop Behavior). Via simulation experiments we discuss the implication of the proposed scheme
