摘要： 给出在P2P直播系统中Peer节点动态变化的情况下保障服务鲁棒性的技术，描述从邻居节点中选择父节点的最优选择方法，研究强节点对区域内全局信息的掌握机制。针对Peer节点动态加入离开对流媒体直播的影响，设计一套加快动态恢复和反应时间的方法。通过原型系统实验及与PeerCast系统比较证明了主要设计机制的有效性和先进性。

Abstract: This paper designs and develops a P2P streaming living broadcast system which ensures node robustness. It introduces a way of choosing best neighbors from some given nodes, makes information of all the nodes in the area known by the strong nodes while minimizing the communication with strong nodes. It must be making quick responses to the new joining in nodes and leaving nodes. Comparison with the PeerCast system proves the design is effective and advanced.

Key words: streaming media, living broadcast, robustness
