分层框架下教育网智能权威域名管理系统的设计与实现

针对CERNET用户对于权威域名解析的需求，基于开源域名解析软件BIND及其DLZ（Dynamically Loadable Zones）拓展，结合Web服务、数据库，设计并开发了一套基于分层框架的智能权威域名管理系统（China Education and Research Network Intelligent Authoritative Domain Management System，简称eIDM），实现了基于源地址的智能解析。使用Python语言和Django框架开发eIDM的Web管理平台，极大的降低了权威域名的管理和维护难度。该系统持续稳定运行多年、操作便捷，为数百个CERNET用户提供便捷的服务，帮助其实现流量调度、负载均衡、安全防护、IPv6升级改造等需求。 关键词：权威DNS；分层框架；在线管理平台；智能解析

Design and implementation of CERNET intelligent authoritative domain name management system on layered framework

To address the needs for authoritative domain name management within the Education Network, a layered system for intelligent authoritative domain management, known as eIDM (China Education and Research Network Intelligent Authoritative Domain Management System), has been designed. This system is based on the open-source domain name resolution software BIND and its Dynamically Loadable Zones (DLZ) extension, integrated with Web services, DNS databases, and backups. Utilizing the Django framework, an online management platform for authoritative domain name information in higher education institutions was developed. This platform allows for real-time synchronization and backup of relevant domains and resource records in DNS, as well as the configuration of intelligent resolution based on source addresses in DNS. The results indicate that the system operates stably and offers convenient operations, achieving its intended objectives.
