摘要

内容分布式网络又称内容分发网络(Content Delivery Network, CDN)。在CDN中，在原有的网络结构基础上增加了一层新的网络结构。网站管理员将更新后的信息发送到离用户最近的节点，以便用户能够更快地获取信息。这意味着一个服务器中的信息被发送到离用户较近的几个服务器。CDN避免了网络拥塞，提高了访问速度。CDN适用于带宽窄、流量大、节点分布不均匀的网络。现在CDN不仅可以支持静态文字和图形，还可以支持流媒体。在未来，CDN将拥有广阔的市场。

Principles of Content-Distributed Network and its applications

Content-Distributed Network is called in another way Content Delivery Network (CDN). In CDN a new layer of network architecture is added to the original ones. The managers of webs send the updated information to the nodes which are nearest to users so that users can obtain it more quickly. That means the information in one server is sent to several server which is near to users. CDN avoids network congestion and increases the speed of visiting. CDN is suitable for the networks which have narrow bandwidth, large traffic and uneven-distributed nodes. Now CDN can support not only static words and graphs but also Streaming Media. In the future CDN will have a promising market.
