[Abstract] In this paper, 5 key technologies of network function virtualization (NFV) are pointed out, including hardware and management technology, virtual layer technology, management arrangement technology, reliability technology, acceleration technology. And the development status and problems are also introduced. NFV is considered as the core technology architecture of the network transformation of operators, and it is the large-scale application of information technology (IT) technology (such as virtualization and cloud computing) in the field of telecommunications. With the maturity of the technology, the NFV architecture of the telecommunications network will be used in the future, and communication technology (CT) and IT will deeply integrate.
