P2P streaming model research based on hybrid underlay topology networks

网络不断演进会改变底层IPv4/IPv6的基础结构。主要讨论在这样的混合网络环境下部署和应用P2P流媒体的关键问题。提出了采用分层思想设计一个完整的P2P流媒体系统模型,该模型在考虑混合底层网络拓扑环境的情况下同时引入了P2P安全认证的机制,在有效提升流媒体分发效率的同时保证了安全性。仿真结果表明,该模型更能满足未来网络演进过程中混合拓扑环境下P2P应用的需要,并具有良好的安全性。

The evolution of Internet result in IPv4/IPv6 hybrid underlay network infrastructure.This paper addressed the architectural and fundamental design issues for supporting P2P streaming applications based on IPv4 and IPv6 coexist network environment.It proposed a layered P2P streaming system model,this model took the hybrid under-layer topology and security mechanism into consideration,which could improve the streaming data distribution efficiency and guarantee the security.Simulation result show that this layered model can satisfy the need of efficiency and security in P2P application in Internet evolvement
