摘要 在骨干网络宽带日益吃紧的背景下,如何将内容更加快速高效地传递到用户终端成为网络改造升级的关键性技术。内容分送网络(CDN),包括内容路由和内容交换两大模块,可以利用有效的网络资源,将内容分发到分布式的服务器集群,使用户与内容距离“更近”。本文阐述了1种Linux平台下的内容分送网络实现方案,构建了基于DNS的内容路由以及第七层的内容交换的系统框架,并且进行了内容路由和内容交换的技术融合。实验结果表明,通过DNS重定向,用户可以从就近的服务节点获取内容,缩短了等待时间。内容分送技术作为下一代网络的核心技术,必然会得到越来越广泛的关注和应用。 With a Content Delivery Network (CDN), the operator could transfer the content to the distributed edge servers and this makes it possible that clients can obtain what they want more quickly without updating the expensive core network. This paper focuses on our experiment in building a CDN network under Linux, including two main modules, content routing based on DNS and 7 layer content switching. Also we established a CDN network with both of these two kinds of technology. This architecture could shorten the response times, which is shown by the test results.
