| 摘 要： | 随着互联网的飞速发展，网络承载内容逐渐由以基于连接的信息交互为主的业务，转变为以内容分享为主（视频）的业务，网络传送大量冗余信息，造成非正常的大规模投资，且业务质量难以保障，迫切需要研究构建与业务发展匹配的网络。通过对内容分享连接关系和通信网络架构连接关系的研究，探究二维差时分发或三维分发等实现方式，改造CDN构建内容边缘节点，优化调整核心网、无线网、承载网架构和网元部署，并考虑引入卫星等天基网络，从而在现有通信网络上构建无标度小跳数网络，实现网络架构与内容分发的匹配。

| Abstract: | With the rapid development of the internet,the network bearer content is gradually transformed from a service based on connection-based information interaction to a service based on content sharing (video).The network transmits a large amount of redundant information,resulting in abnormal large-scale investment.And the quality of the service is difficult to guarantee,and it is urgent to study and construct a network that matches the business development.The content sharing connection relationship and the communication network architecture connection relationship were studied,and the two-dimensional poor time distribution or three-dimensional distribution and other implementation methods were explored.CDN was constructed to construct the content edge node,and the core network,wireless network,bearer network architecture and network element deployment were optimized.And space-based network such as satellite was considered to introduce to build a scale-free small hop network on the existing communication network to achieve matching of network architecture and content distribution. |
