摘要

提出了一种基于综合因素的点对点媒体流调度算法。在CFB中，考虑到数据块供应商的数量和紧迫性，为每个数据块定义优先级，并有效地评估相邻数据块的带宽。对等体根据优先级和带宽向邻居请求块。仿真结果表明，所提出的点对点媒体流CFB调度算法在对等体平均吞吐量、连续性指数和启动延迟等方面优于传统调度算法。

Comprehensive-factors-based scheduling algorithm for P2P media streaming

A comprehensive-factors-based (CFB) scheduling algorithm is proposed for Peer-to-Peer media streaming. In CFB, considering the number of chunks' suppliers and urgency, a priority is defined for each data chunk and the neighbours' 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.
