中文摘要：

融合网络中的异构P2P流媒体系统中具有多种终端、应用及节目类型,使得用户行为模式复杂,为系统稳定性带来了挑战。针对以上问题提出融合网络异构P2P流媒体系统稳定性增强策略。通过分析流媒体系统用户日志,确定用户行为影响因素,在此基础上对不同类型的用户行为进行收集及拟合,进行基于可靠性分析的路由、资源信息维护及合作节点选择,提高了系统资源信息维护准确性及节点间数据合作有效性。使用真实系统日志驱动的仿真实验验证了该策略的效果。

英文摘要：

Heterogeneous P2P streaming system in integrated networks contains multiple types of terminals,applications and program contents,which brings in complex user behavior patterns and make challenge to system stability.After extracting user behavior affect factors through analysis of streaming system user trace,this paper proposed an anti-churn scheme for heterogeneous P2P streaming（ACSHP） to solve these problems.ACSHP collected and fited heterogeneous user behavior data to improve maintain strategy of routing table,published resource information and cooperating peer selection,which improved the accuracy of resource information maintaining and the effectiveness of data cooperation between peers.Real system trace-driven simulation verifies the effectiveness of the strategy.
