中文摘要: 为了提高P2P流媒体数据传输的效率，提出一种基于综合因素的P2P流媒体数据调度算法，该算法综合考虑数据块的提供者数量和紧急程度定义数据块优先级，并对与提供者之间的网络带宽进行有效估计，根据优先级和带宽调度P2P数据请求的次序和方向。仿真结果表明，该调度算法在节点吞吐量和系统连续性指标以及启动延迟方面比传统的P2P流媒体调度算法有明显提高。

Abstract:A comprehensive factors-based (CFB) scheduling algorithm is proposed for Peer-to-Peer media streaming. In CFB scheduling algorithm, considering the number of chunk’s suppliers and urgency，a priority is defined for each data chunk and the neighbors’ bandwidth is effectively evaluated. A peer requests chunks from neighbors according to priorities as well as bandwidth. Simulation results show that the proposed CFB scheduling algorithm for Peer-to-Peer media streaming outperforms conventional scheduling algorithms in peer average throughput, continuity index and start delay.
