【摘要】 DHT(分布式Hash表)是P2P网络中的一种结构化定位技术.针对DHT很难解决的抖动问题,提出了反向邻居节点数的概念,计算了几种常用的DHT的反向邻居节点数,找出了影响DHT抖动处理代价最重要的4个因素.通过比较不同DHT的这4个指标,发现了有利于提升DHT抖动处理能力的关键技术.更多还原

【Abstract】 Distributed Hash table is a structured location technique in peer to peer network. With the problem of churn which is difficult to handle by DHT, the number of reverse neighbour nodes is proposed, which is a new concept. The number of reverse neighbour nodes about several usual DHTs is calculated and the most significiant factors which affect the cost of DHT handling churn are found. Finally,by comparing the four metrics of different DHT,the pivotal technique about how to enhance the ability of DHT handling churn is discovered.更多还原
