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。
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.
