【摘要】 介绍了P2P网络拓扑结构的分类和发展情况,对目前对等网中DHT算法CAN、Chord、Pastry、Tapestry以及Kademlia进行了比较。提出了一种网络电话系统——利用Kademlia建立重叠网,并且在该重叠网基础上传递SIP数据包。仿真结果表明,基于Kademlia的网络电话,在查找成功率以及查找延迟方面都占有优势,具有良好的实用性。更多还原

【Abstract】 The classification and development of P2P network topology is introduced. The comparison is made for DHT algorithms such as CAN,Chord,Pastry,Tapestry and Kademlia in current P2P network. A network telephone system,which establishes overlay network by use of Kademlia and transfers SIP data packets on the basis of the overlay network,is presented. Simulation results indicate that the network telephone based on Kademlia has the advantages in search success rate and search delay. It has good practicability.更多还原
