Anti-churn research of integrated heterogeneous P2P streaming system
融合网络异构P2P流媒体系统抗扰动性研究

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 streamingACSHP 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.
