Abstract:

内容分发网络(Content Delivery Network)是新兴的网络加速技术，可以避开互联网上影响数据传输速度和稳定性的瓶颈和环节，使内容传输更快、更稳定。CDN有效的利用DNS，将用户重定向到附近的CDN网络的边缘节点服务器来提高用户获取内容信息的效率和质量。DNS重定向技术的运用为CDN网络带来了显著的优势和灵活性。本文介绍了CDN的基础原理、工作流程及CDN域名监测的必要性，采用基于J48决策树算法对CDN域名进行检测，构建CDN基础资源库。实验结果表明，该算法能有效提高CDN域名检测的效率，准确率达到98.8%，召回率达到98.1%。
Content Delivery Network is an emerging network acceleration technology. CDN can avoid bottle-necks and links on the Internet that affect the speed and stability of data transmission, that makes the content transfer faster and more stable. CDN effectively utilizes DNS that redirects user to the edge node server of the nearby CDN network to improve the efficiency and quality of the user’s access to content information. The application of DNS redirection technology brings significant advantages and flexibility to CDN. This paper introduces the basic principles, workflow, and the neces-sity of CDN domain name monitoring. It uses the J48 decision tree algorithm to detect CDN domain names and builds a basic CDN resource library. Experimental results show that the algorithm can effectively improve CDN domain name detection efficiency, with an accuracy rate of 98.8% and a recall rate of 98.1%.
