[Abstract] Next generation network transformation is driven by technology development and business requirement. Software defined network(SDN) and network function virtualization(NFV) are the basis for the next generation network. The essence, development, and the major challenges of SDN and NFV are proposed in this paper. Moreover, we discuss the key problems in the development of next generation network, and point out that the combination of 5G network and the next generation network would be significant.
