  With fast development of Internet of Everything (IoE) 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
paper, a cybertwin based next generation network architecture is proposed to
accomodate the evolution from end-to-end connection to cloud-to-end connection
in the future network. As a digital representation of human or things in the
virtual cyberspace, cybertwin serves in multiple capacities, such as
communications assistant, network data logger, and digital asset owner. The new
and unique characteristics of the cybertwin make the proposed network to be
flexible, scalable, reliable, and secure. Further, 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,
communications) resources. We also propose cloud operator, a new operator that
can provide and manage the resources to the end users and offer location and
authentication services for human and things in the cyberspace. Some promising
and open research topics are discussed to envision the challenges and
opportunities of the cybertwin in the future network architecture.
