The software defined network brings the networks into the era of intelligence and centralization by separating and forwarding control.However,with the diversification and complexity of the Internet of Things,industrial Internet and other scenarios,future networks need to support on-demand interconnection and task driven requirements,and the traditional TCP/IP identifier system cannot meet the characteristics of the future complex networks.Therefore,how to design a new Internet identifier has become the most urgent and core research content in the information field.This paper analyzes the hierarchical structure flaws of TCP/IP protocols and creatively proposes a multi-dimensional identifier system and its working mechanisms.The multi-dimensional identifier network knowledge space provides unified identifiers,unified scheduling,status awareness and topology storage for the entire network's resources,providing an analysis and adaptation basis for realizing differentiated and customized communication network services.
