【摘要】：统计数据显示,P2P、在线视频已经彻底统治了当今的互联网,互联网80%的总流量都来自P2P和在线视频应用。这些应用给客户带来丰富的互联网体验的同时,也给网络的运营者、管理者带来了很大的挑战。P2P和在线视频应用占用了运营商城域网大量的带宽资源,而其他一些业务的质量无法保障,用户抱怨增多,粘合度急剧下降,造成用户流失。常熟广电在发展宽带业务的过程中也出现了类似的问题。有限的互联网出口带宽被大量在线视频、P2P业务流量占据,用户体验变差,投诉量日益增长。本文首先提出了常熟广电建设互联网CDN(内容分发网络)平台的必要性,并对建设CDN平台的几个关键技术进行了研究和阐述;然后对平台的总体设计和各个子系统进行研究和部署;最后对整个平台的运营情况进行了测试和总结。实践证明,互联网CDN平台的部署,对于解决常熟广电互联网出口带宽不足的现状,加速用户体验,具有积极的意义。
[Abstract]:Statistics show that online video has completely dominated the Internet today. The total traffic of Internet 80% comes from P2P and online video applications. These applications bring customers a rich Internet experience, but also give network operators. The manager has brought great challenges. P2P and online video applications have taken up a lot of bandwidth resources in the operator's metropolitan area network, while the quality of some other services is not guaranteed, user complaints have increased, and the degree of adhesion has plummeted. A similar problem has arisen in the development of broadband services in Changshu Radio and Television. The limited bandwidth of Internet exports is occupied by a large number of online video and P2P traffic, and the user experience becomes worse. The number of complaints is increasing day by day. Firstly, this paper puts forward the necessity of building Internet CDN (content distribution network) platform in Changshu Radio and Television, and studies and expounds several key technologies of building CDN platform. Then the overall design of the platform and the various subsystems are studied and deployed. Finally, the operation of the platform is tested and summarized. Practice shows that the deployment of the Internet CDN platform, It is of positive significance to solve the shortage of bandwidth of Changshu radio and television Internet export and accelerate the user experience.
