摘要
提出一种新型的分层分簇结构的P2P覆盖网络模型HCPON。该模型根据能力对节点分层处理,分簇聚合,分别应用不同方案优化覆盖网络结构,兼顾了节点的能力差异性和位置特性。仿真实验表明,该模型具有很好的可扩展性和鲁棒性,能够满足大规模流媒体服务需求。
A novel Hierachical-Cluster P2P Overlay Network （HCPON） model is presented for live streaming media.Considering the heterogeneity and different locations of the nodes,the model organizes nodes into different hierarchies and clusters,and optimizes overlay structure using different strategies.The simulation shows that the model is scalable and robust,which can meet the need of large scale live streaming media service.
