Abstract

This paper proposes a DiffServ-based multicast media gateway, called DiffServ-based Multicast Router (DSMRouter), to guarantee QoS and scalability for multimedia presentation. To reach the QoS goals, the proportional fairness scheduling strategy is proposed for layered media flows, including I-frame, P-frame and B-frame flows, to determine the approximate reserved bandwidth. Additionally, the DSMRouter system dynamically changes the sending rates of various service queues to ensure that layered media packets with higher priority are always sent before those with lower priority. The proposed PFS strategy has been experimentally tested on several layered-video streams. The results reveal that the proposed scheme outperforms others with a substantial reduction of bandwidth reservation even given tight delay bounds. The experimental results of the DSMRouter system on DiffServ networks also reveal the capability for dynamic bandwidth adjustment in various networking situations.
