下一代互联网中名系统的研究

学术界近期提出了基于扁平结构的分布式哈希表（DHT）名系统,用以克服现有名系统域名解析系统（DNS）存在的缺陷,如不支持数据的移动、复制等,但由于其解析时延较大,不适于实际应用。为此,综合DNS名系统及DHT名系统的优点,设计了两种新的系统：第一种系统采用One-hop DHT形式,三层环结构实现,适于小环境应用;第二种采用混合结构DHT形式,分域实现,适于全球性应用。经理论分析证明这两套系统在实际应用中是可行的。

Research on the Next Generation Naming System

Academics recently proposed a new naming system based on the flat structured domain name system （DNS） to overcome defects in the existing DNS. Such defects include the inability to support movement and replication. Due to lengthy time delay, DNS is not suitable for practical application. This paper introduces two improved structures which combine the advantages of DNS and DHT. The first system uses one-hop DHT form and three ring structure （suitable for smaller environments）, while the second adopts a hybrid structure of DHT and Fenwick （suitable for global application）. Through theoretical application, it is proven that these systems are feasible for practical use.
