摘要：

流媒体应用已成为当今互联网承载的主要业务之一，如何支持大规模用户在线使用流媒体，并保障流媒体的服务质量（QoS）尤为重要。依据P2P 技术的特点和流媒体系统的发展，对比分析了典型流媒体系统的流服务策略，总结归纳了系统的优点与不足。以节点选择机制、数据调度机制、缓存机制、容错机制、激励机制为评价指标，重点对当前流媒体系统服务质量研究进行评述。最后对保障大规模可信流媒体服务质量的研究方向进行了展望。

Abstract:

With the quickly development of science，streaming media application has become one of the main services over internet. How can it support the large-scale customers and improve the quality of service . Based on the characters of P2P，it compares and analyzes the typical flow service strategy of media streaming system，and summarizes the features and shortcomings of different systems. Moreover，it takes the node selection，data scheduling，cache mechanism，error-tolerance，and incentive mechanism as the evaluation index，focuses on the quality of service of current typical streaming media system. Finally，future works about the quality of service of media streaming systems in P2P networks are outlined.

Key words: P2P streaming media, quality of service, reputation, incentive, scheduling
