[Abstract] Network function virtualization (NFV) based core network is an important trend in information development, and China has made remarkable progress in its development, structure and application. The NFV-based core network has some key problems in standardization, reliability, security, and performance. Only when these problems are solved can it be deployed. The construction of unified resource collaborative arrangement on integration of telecommunication and IT, the research on the cloud based network architecture of new data center networking, and network evolution and innovation are all challenges for operators.
