基于ZIGZAG的流媒体直播系统的研究和实现

Research and Realization of Media Streaming Live System Based on ZIGZAG

分析了现有P2P流媒体系统存在的问题,研究了ZIGZAG系统控制拓扑和数据传输拓扑两方面的主要技术,设计并实现了一个单源的基于ZIGZAG模型的P2P流媒体在线直播系统P2P-Streaming。系统通过局域网运行测试,分析表明P2P-Streaming有效地降低了节点开销,具有很好的扩展性。

This paper analyzes the problems of existing P2P media streaming systems and makes research on the control topology technology and data topology technology of ZIGZAG. Hereby an P2P live media streaming system-P2P-Streaming is designed. Moreover, it implements the P2P-Streaming system and runs it at the LAN. The analysis and test shows that P2P-Streaming reduces the overhead of peers efficiently, and has a good scalability.
