With the fast development of Internet-of-Everything and its applications, the ever increasing mobile Internet traffic and services bring unprecedented challenges, including scalability, mobility, availability, and security, which cannot be addressed by the current clean-slate network architecture. In this talk, a cybertwin based next generation network architecture is proposed to accommodate the evolution from end-to-end connection to cloud-to-end connection in the future network. As a digital representation of humans or things in the virtual cyberspace, cybertwin serves in multiple capacities, such as communications assistant, network behavior logger, and digital asset owner. We advocate a new cloud network operating system which can work in a distributed way through a real-time multi-agent trading platform to allocate 3C (computing, caching, communication) resources. We also redesign the radio access network architecture, which fully decoupled the control BSs and data BSs and entirely separate uplink and downlink, which can enhance the spectrum utilization, reduce the network energy consumption and improve the quality of user experience.
