Improving QoS of audio and video packets in MPLS using network processors

Growing bandwidth demand in the Internet requires new algorithms and architectures to provide a high degree of QoS. Further, to complicate the problem of Traffic Engineering, real time data processing requires more priority than non-real time data processing. In this paper, we present an effective solution for improving QoS of audio and video packets in MPLS networks under real time traffic conditions. The contribution of this work is two fold. First, we investigate the impact of increased traffic on QoS parameters under heavy loading conditions and further we propose an efficient routing mechanism based on active networking concepts [1] to satisfy QoS requirements of audio and video packets.
