dc.description.abstract Quality of service (QoS) provisioning, in today's IP networks, is becoming more important due to the tremendous growth of real-time and multimedia applications. However, one of the challenges to achieving QoS requirements is how to allocate the bandwidth to various applications. One solution is to assigning bandwidth dynamically instead statically. In this paper, a reconfigurable bandwidth allocation technique based on QoS provisioning over DiffServ router is proposed. The technique aims at improving the performance and bandwidth utilization of multimedia applications by allowing video traffic class to share the bandwidth of other traffic classes that can tolerate a certain percentage of packet loss without any degradation of quality. This property is used to adjust the bandwidth assigned to video traffic according to the percentage of the packet loss of other classes. As a study case, the reconfigurable bandwidth allocation scheme is applied to a network model based on a modified deficit round robin (MDRR) scheduler. It can be seen from the simulation, using OPNET modeler 14.5, that the proposed QoS model improves the QoS of multimedia traffic. en_US
