Polymorphic Smart Network: An Open, Flexible and Universal Architecture for Future Heterogeneous Networks

摘要

Burdened with the specialized bearing requirements brought by the deep fusion of the Internet and the economic society, the current Internet is faced with a series of great challenges including intelligence, diversification, personalization, robustness and efficiency because of some defects such as rigid structure, simple bearing structure based on IP, and disability in suppressing unknown threats. This paper proposes to improve the function, performance, efficiency and security of the Internet from the perspective of network architecture, introduces the "structure definability" to all layers of the network, and provides a network architecture with polymorphic presentation of network functions in all layers called Polymorphic Smart Network (PINet). PINet supports full-dimensional definition and polymorphic presentation of addressing and routing, switching mode, interconnection mode, network element, transmission protocol, service properties and so on. Experimental results have verified that PINet supports the incremental evolution of the Internet and fundamentally meets the business requirement of network intelligence, diversification, personalization, high robustness and high efficiency.
