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 architecture 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 discussed

including Standard Pattern

Relay Pattern

Consolidation Pattern and UCL Only Pattern.Findings of this paper provide theoretical supports for further study on the strict definition and specification of the broadcast-storage network architecture.
