摘要

内容共享是实现互联网普惠全民（The Internet is for Everyone）的重要方面，为此，中国工程院李幼平院士提出以Internet为主结构而以播存网络为次结构的双体系结构内容共享网络，简称双结构网络DAN（Dual-Architecture Network），本文首先介绍DAN的实现模型并进行形式化描述，然后定性分析DAN的内容共享机理和内容运营模式，同时采用2ACT模型进行定量分析，最后通过原型系统进行原理性验证.从多个维度综合阐明DAN的内容共享能力.

Abstract

Content sharing plays the essential role to achieve the vision of "The Internet is for Everyone". To this end

Prof. Li Youping

academician of the Chinese Academy of Engineering

pioneered the concept of DAN (Dual-Architecture Network)

which is composed of primary architecture (refers to Internet) and secondary architecture (refers to broadcast-storage network). In this paper

firstly the implementation model of DAN and its formalized description are exhaustively presented

and then qualitative analyses for the content sharing mechanism and content business model are conducted. Furthermore

quantitative analysis is conducted by applying the 2ACT model. Finally

the feasibility is verified through a prototype system. The content sharing capability of DAN is eventually demonstrated in terms of theoretical analysis and system implementation.
