MazeLive：接收端驱动的P2P直播系统

Mazelive: Receiver-driven peer-to-peer system for live media streaming

Mazelive P2P流媒体直播系统融合了Overlay组播较成功的经验:多父节点传输、分布式Overlay构建,同时具有一些新的优化:在伙伴发现上采用Push-PullGossip协议[1];接收端驱动,优化机制和策略,最大化流质量,增加冗余连接来提高容错性;设计了多源数据请求滑动窗口协议保证数据传输稳定,搭建了一套实际运行的系统。研究结果表明,该系统具有高效、可扩展、低负载等特点。

MazeLive P2P live streaming system integrated successful functionalities from overlay multicast, such as data transmission from multiple parent nodes and the distributed overlay structures. Moreover, several improvements are presented： Push-pull Gossip protocol is applied in peer selection. Receiver maximized its streaming QoS by optimizing mechanism and strategies, and preparing extra peer connections for fail-over. The sliding windows mechanism is designed to receive data from multi-source for more stable data transfer. The real system is implemented and had run for a while, which proves that the algorithms are effective, easily extendable and efficient, etc.
