智能域名解析技术在多出口校园网中的应用

Application of Intelligent DNS for Multi-exports Campus Network

针对目前国内高校校园网普遍存在的多出口应用现象,分析了不同ISP用户访问校园网内部资源时存在差异性的原因,提出了通过智能分源动态域名解析技术解决这一问题的基本原理和实现方法。在此基础上,基于Linux操作系统下的BIND软件,通过对View功能的分析,给出了一种较新的、低成本的、高效可行的解决方案,并提供了详细的配置示例和操作细节。

For the multi-exports phenomenon in current campus network, this paper analyzes the reasons that different users using different ISP to access campus network have different effect, puts forward the basic principle and method to solve this problem through using intelligent sub-source dynamic DNS technology. On this basis, through the functional analysis of view based on the BIND software in Linux operating system, this paper gives a new, low-cost, efficient solu-tions, and provides a detailed configuration samples and operation details.
