针对互联网主流应用范型向公共内容服务的转变，采用基于物理变革和二元网络思维的研究思路，主张为现有互联网体系结构增添充当次级结构的播存网络。介绍了播存网络的设计理念、主要特色及关键实现机制，给出了播存网络体系结构的普适模型及其数学描述。在此基础上，重点研究了播存网络体系结构的主要实现模式，包括标准实现模式、中继实现模式、并合实现模式和UCL Only模式等。为播存网络体系结构的严格定义及规范描述奠定了理论基础。%Focusing on Internet’ s emerging paradigm of ubiquitous content sharing ,this paper emphasizes on a physically revolutionary and dual-structural approach to the future Internet architecture ,which insists on complementing the current Internet ar-chitecture with a secondary structure ,the broadcast-storage network .By analyzing the concepts ,features and key mechanisms of the broadcast-storage network ,a general architecture model of broadcast-storage network and its mathematical description are presented . Based on these foundations ,some principal realization patterns of the broadcast-storage network architecture are addressed and dis-cussed ,including Standard Pattern ,Relay Pattern ,Consolidation Pattern and UCL Only Pattern .Findings of this paper provide theo-retical supports for further study on the strict definition and specification of the broadcast-storage network architecture .
