To enhance P2P media streaming system’s overall performance and improve the playback quality of the nodes,according to the great start delay time and bandwidth utilization is not high issue in existed algorithm,an optimize schduling algorithm(LOSA) is proposed,which can dynamically adjust the urgent pending request.This algorithm not only considered the time characteristics of live media streaming,but also took account of how to reduce the waiting time of emergency data request and make the best of the peer’s upload bandwidth.Experimental results are proved that the scheduling algorithm diminishes the accumulated latency observed at end users and improves the continuity of media streaming.
