摘　　要：随着互联网多媒体信息的快速发展,内容分发网络(CDN)技术的研究和应用已成为当前网络技术发展的重要领域之一。本文解析了CDN的工作原理及关键技术,结合自然资源部政务信息服务平台的实践应用,阐述了CDN的分布式架构部署和动静态分类加速策略,梳理总结了当前技术条件下超文本传输安全协议(HTTPS)安全加速策略的优势和劣势,指出了CDN在HTTPS安全加速方面存在的缺陷和隐患,提出了“双证书”的解决方案。通过实际应用数据监测对比,CDN在跨运营商数据传输、带宽资源拓展、访问速度提高、源站安全性增强方面具有明显技术优势,对提升自然资源政务信息服务水平和质量起到了积极作用。With the rapid development of Internet multimedia information,the research and application of Content Delivery Network(CDN)technology has become one of the important fields in the development of network technology.This paper deeply analyzes the working principle and key technologies of CDN.Combined with the practical application of government information service platform of Ministry of Natural Resources,this paper introduces the distributed architecture of CDN and the dynamic and static delivery strategy,summarizes the advantages and disadvantages of CDN Hypertext Transfer Protocol Secure(HTTPS)under the current technical conditions,points out the application difficulties of CDN HTTPS,and finally puts forward the"double certificate"solution.By comparison with the actual application data monitoring,CDN has obvious technology advantages in solving data transmission,improving broadband resources,increasing access speed and enhancing source station security.CDN has played a positive role in promoting natural resources government information service level and quality.
