摘　　要：该文设计了一种自适应随机线性网络编码P2P实时媒体分发系统。提出了一种网状网络拓扑下的编码窗自适应随机线性网络编码算法。仿真结果表明,该算法具有很好的效果:对网络带宽要求低;无需全局网络拓扑信息;平均延迟小,连续性好;鲁棒,可扩展性强。In this paper, ARLNCStream, a novel algorithm of adaptive random linear network coding for media streaming, is presented. When distributing contents using random linear network coding, every node adjusts its coding window in an adaptive way and then requests coded block of an appropriate size from its partners. The solution makes nodes collaborate well with potential partners. Without knowledge of global network topology, ARLNCStream archives quiet low segment missing ratio. ARLNCStream is also robust and scalable. Simulations demonstrate the excellent performance of the solution.
