中文摘要：

P2P流媒体是一种极具潜力的流媒体内容分发技术。在P2P流媒体系统中采用网络编码，有利于进一步提升系统整体性能。针对目前流行的基于数据驱动覆盖网络的P2P流媒体系统框架，根据直播和点播这两种流媒体播送模式，深入讨论和分析了具有代表性的网络编码P2P流媒体技术方案的实现机制及其优缺点。最后，对该方向的研究趋势进行了展望。

英文摘要：

P2P streaming is a promising media content distribution technology. Network coding can be adopted into a P2P streaming system to further improve its overall performance. Focused on currently popular data-driven overlay network based P2P streaming system framework and based on two streaming modes, i. e. , live streaming and on-demand streaming, the implementation mechanisms, merits and drawbacks of the typical P2P streaming schemes using network coding were discussed in detail. At last, the open issues of this research direction were presented.
