Future architecture and evolution of communication network
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.
