【摘要】 互联网是资源、网络协议、资源标识与寻址机制组成的信息空间。资源包括有形的物理资源，比如网络服务器、存储设备等，也包括虚拟资源，比如信息资源、某种网络服务等。为了充分开发利用好互联网上的各类资源，有效的资源标识与寻址机制至关重要。目前互联网上应用最广泛的资源标识与寻址技术就是域名技术，可以说域名技术是互联网上最成功的技术之一，是互联网的基础性技术，几乎任何一种互联网应用都跟域名有关。简单、高效是域名技术的特点，也是域名技术获得成功的一个主要原因。但是随着互联网的发展，更多应用和资源类型出现，域名技术要满足全部互联网资源标识与寻址的需求有些力不从心。 本文以对域名技术的研究为基础，指出了域名技术的不足，并针对这些不足提出了相应的一些解决方法。结合当前互联网发展应用的情况，设计了一种统一的互联网资源标识与寻址机制，并将这种机制应用于域名系统。本文的主要贡献和创新点有： 1、研究了中文域名繁简体等效的问题，提出了基于IDN-Admin算法实现中文域名繁简等效的解决方案，设计了实现算法以及用于方案实现的中文域名异体等效对照表。 2、研究了ENUM用户隐私信息的保护，对ENUM记录资源访问进行权限控制，提出了基于用户认证的ENUM记录级授权访问解决方案。 3、提出了基于DNS的网络关键词寻址技术及规范。 4、研究了IPv6环境下的DNS技术特点。 5、提出了一种统一的互联网资源标识与寻址技术：通用名字服务系统，并将这种技术应用于DNS实现。更多还原

【Abstract】 Internet is the information space with the collection of resources, network protocols, resource naming and address mechanism.The resources include not only the physical resources such as the network servers and storage devices, but also the virtual resources such as information and some network services.How to build the efficient address mapping mechanism and identify these resources is crucial for efficient use of all kinds of resources available on the Internet.Currently the most popular technology for resource naming and addressing is the domain name technology, which is one of the most successful technologies. Domain name technology is the base of Internet, with which many Internet applications relate. Simplicity and efficiency are the key characters of domain name technologies, which are also the main reasons of why domain technologies are so successful. With the explosive growth of Internet, more and more types of applications and services are available. Domain name technology is not capable enough to identify and address all these resources.This paper describes the domain name technology and its disadvantages. To deal with these disadvantages, this paper gives some solutions. We design a new unified mechanism of resource naming and addressing, which improves the functions of domain name system and is applied to domain name system.The main contributions and creative ideas are:1. Do some research on the issues of equal of simple Chinese characters and traditional Chinese characters, propose a solution based on the algorithm of IDN-Admin to implement the equal of simple Chinese characters and traditional Chinese characters, and design a Chinese Domain Name Characters Variant Table and its algorithm.2. Do some research on the protection of the private information of ENUM users and the access control of ENUM resource record, and propose a solution based on the authentication of ENUM record access.3. Propose a keyword addressing technology and its specification based onDNS technology.4. Do some research on the characters of DNS technology within IPv6 environments.5. Propose an unified Internet resource naming and addressing technology named with uniform naming service system which is applied into DNS.更多还原
