A self-adjusted buffer control for P2P live streaming

Abstract

Real-time multicast live streaming system can use peer-to-peer (P2P) technology to keep stability and scalability without any additional support from the underneath network. Our proposed scheme focuses on the mesh architecture of P2P live streaming system and uses dynamic buffer to substitute the traditional fixed buffer owning a limit of quality of service (QoS). According to the simulated results, the self-adjusted dynamic buffering mechanism can adjust buffer to avoid the frozen or reboot of streaming based on the input data rate and it is suitable for the violently dynamic P2P environment. Hence, our proposed scheme can be workable because the modification of buffering mechanism varies the existing P2P live streaming system less to improve quality of experience (QoE) more.
