基于CDN架构的WEB服务器的设计与实现

The Design and Implementation of WEB Server Based on CDN Architecture

在网络中,可能出现大量用户在同一时间节点访问同一台服务器来获取同一网络资源,如春运抢票和高校网上选课。针对这些情况,提出了一种CDN技术,将几个地理位置不同的镜像WEB服务器从源WEB服务器上复制内容服务到本地,让用户就近获取内容,克服了互联网固有的局限性,并提供了一种改进资源获取的服务方式,减少请求响应时间,增加了用户体验,以及提高了安全性。

In the network, the same server may receive a large number of users＇ access at the same time node to get the same network resources, such as travel tickets and college online course selection. In view of this situation, CDN technology is proposed, combines several geographically mirrored WEB server copy contents from a source WEB server to the local, allows users to get content,overcomes the inherent limitations of the Internet, and provides an improved resource acquisition services, reduces response time, increases the user experience, and improves security.
