摘　　要：在理解域名解析系统(DNS)的基础上,阐明了在当前网络应用中DNS系统所存在的一些缺陷,如不支持数据的移动和复制,负载不均衡等.本文设计了全新的名字解析映射系统来克服这些缺陷,并把它应用在一体化网络中.该名字解析映射系统采用三层重叠网络结构:中继层、实现层和维护层,中继层控制用户接入,实现层和维护层协同工作,实现名字的解析映射.理论分析和试验结果表明,该设计克服了域名解析系统存在的缺陷,将在一体化网络的设计中起到重要作用.Based on the general principle and mechanism of domain naming system（DNS）, this paper describes the shortcomings of DNS in today＇s use, such as it cannot provide service again after the data movement or replication and cannot achieve load balance. We design a new naming system based on new Universal Network to overcome the drawbacks. In this system, there are three layers： Relay layer, Achievement layer and Maintain layer. Relay layer is in charge of users＇ switch-in, and Achievement layer and Maintain layer work together to accomplish the name resolution. Both theoretical analysis and experiment results show that this design overcomes the shortcomings of DNS, and will play an important role in the design of Universal Network.
