播存网络体系结构普适模型及实现模式

General Architecture Model of Broadcast-Storage Network and its Realization Patterns

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 Intemet＇ s emerging paradigm of ubiquitous content sharing, this paper emphasizes on a physically revolutionary and dual-structural approach to the future Intemet architecture, which insists on complementing the current Intemet 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,includlng 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.
