P2P流媒体系统模型及关键技术研究

Research on P2P streaming media model and key techniques

介绍了典型的P2P流媒体系统模型,并指出基于多播树协议的服务模型与基于Gossip协议的服务模型的区别。分析了对P2P流媒体系统的节点的调度算法、数据存储、资源发现、内容分发等关键技术,在此基础上指出了P2P流媒体系统进一步的研究方向。

This paper gives an introduction to typical P2P system models. Then it points out the differences between models based on Gossip protocol and muhicast tree protocol. Then it shows some key technologies of typical P2P system models, such as the scheduling algorithm at one node, data storage, resource discovery, content distribution and so on. Finally, open issues in P2P media streaming systems for further study are discussed.
