| 摘 要： | CDN是一个建立并覆盖在互联网,并由分布在不同区域的节点服务器群组成的虚拟网络。CDN采用缓存、复制、负载均衡和客户请求重定向等技术,将信息资源推向网络边缘,使得客户可以从"最近最好"的服务器快速访问到所需的内容,从而提高了终端用户的访问速度。文中简要介绍CDN的概念和技术,包括CDN基本工作原理,内容路由的设计原则和机制比较,节点内容引擎比较。通过CDN的技术方案,为宽带的发展提供一些技术参考。

| Abstract: | CDN is a fictitious network, covered in Internet and made up of nodal servers in different areas. Through caching, duplicating, load balancing and user request redirecting, CDN pushes information resources to network edges to provide end users with the best and most available servers to access various contents. A brief view of CDN technology was presented, including basic working principles of CDN platform, design principles and mechanism compare of the content routing, and the nodal content engine was compared. The establishment of information sources in broadband networks was also mentioned. |
