摘　　要：主要从资源定位和数据传输两个方面概述P2P流媒体系统的关键技术。资源定位主要介绍结构化和非结构化资源索引及节点选择方法,节点选择则从节点物理位置和节点异构性讨论。数据传输主要讨论数据拓扑结构、数据调度模式、数据片选择策略及与SVC、MDC视频编码的结合。In this paper, the key technologies of P2P streaming is divided into resource orientation and data transmission. Resource orientation is mainly presented in structured and unstructured resource index. Meanwhile, the physical location and heterogeneity of peer is taken into account to discuss the methods of selecting peers. Data transmission relates to data topology, data scheduling, methods of choosing data chunk and combination with video cod- ing such as SVC and MDC.
