A new asymmetric network architecture for ubiquitous information sharing

The application of Internet is being changed from information exchange to information sharing, along with the durative rapid growing of internet information and demands. However, the study on the network survey indicates that the current network architecture is being unbearable due to the masses of redundant data transmission by the information sharing services. This paper proposes a new asymmetric network architecture for ubiquitous information sharing, which bases on "small-world" theory and distributed caching technique. Then the initiative service mode and some key techniques of the new architecture for mainstream Internet information sharing are presented. The experiment on Tunet shows that new architecture has high covering and efficient indexing characteristic, moreover, has remarkable advantages in delay and bandwidth.
