dc.description.abstract Quality of Service (QoS) is becoming increasingly important with the rise of multimedia applications (such as voice over IP (VoIP), video conferencing, and so on) in public data networks. These applications demand real-time service, while the networks should still be able to transfer also other traffic reliably (e.g., data, email, and WWW). In this paper, we concern how to improve the QoS of multimedia applications (Voice and video traffic) in DiffServ internet router by using the reconfigurable technique. Therefore we design an QoS model called Reconfigurable Scheduling Model (RSM) for real-time traffic in Diffserv router. In this model, we use the strict priority technique for the voice traffic to reduce the delay and then improve the QoS. While for video traffic, a hardware reconfigurable technique is used to provide the flexibility that improves QoS levels when compared to other techniques such as software-only implementations. This permits the run-time reconfiguration of the router resources, i.e., to change their functionality (from one scheduling algorithm to another), to adapt the fluctuation in traffic parameter. We choose two of the most widely used schedulers (CBWFQ, and MDRR) to support real-time allocations and to improve the QoS of video traffic. The reconfiguration or the switching between those two schedulers is based on queuing delay of the video traffic. To evaluate the proposed approach, the queuing model was built and simulated with MATLAB Simevents and Stateflow components. The result of simulation shows an improvement in QoS of voice and video traffics. en_US
