Abstract :
This paper presents a DiffServ based adaptive QoS model for real-time interactive traffic in constrained bandwidth IP network without over provisioning the users. A WRR based QoS scheduling algorithm has been implemented to allocate the network resources to the users. A tuning parameter for VBR real-time traffic is also introduced in order to provide fair performance to the non real-time traffic as well. The QoS model is implemented at the transmitter edge of the network. Edge switches and routers are configured with the proposed algorithm. The simulation (using NS2) and experimental results (using a test bed with real time network scenario) are presented for validation of the proposed model.
