P2P Live-Streaming Application-Aware Architecture for QoS Enhancement in the EPON

Managing a single state-of-the-art ethernet passive optical network optical line terminal (EPON OLT) that can support many customers with different multimedia services and quality of service (QoS) is a challenge. Peer-to-peer (P2P) live streaming is one of the most popular multimedia applications in access networks, especially in the Asia-Pacific region, which requires higher QoS, but such streaming is difficult to manage. Therefore, a new approach is required that can provide flexible control to Internet service providers (ISPs) over their networks. In this paper, we propose a P2P application-aware architecture at the OLT and optical network unit (ONU) that aims to improve overall QoS and, at the same time, preserve user-perceived quality and provide ISPs with flexible control over P2P live-streaming traffic. Finally, a new application-aware dynamic bandwidth allocation (ADBA) is presented. Simulation results show that the proposed architecture can improve the overall QoS in terms of mean packet delay, system throughputs, and jitter, and it can also alleviate inter-ISP traffic bandwidth.
