[Abstract] Through the separation of hardware and software, and standardization of hardware, network function virtualization (NFV) technology enhances the efficiency of the utilization of hardware resources, and reduces technical barriers and development costs, and significantly reduces the Capital Expenditure (CAPEX) and Operating Expense (OPEX). The evolution scheme of the metropolitan area network(MAN) element is introduced, and the fast and effective way of leading the current network deployment into MAN at the transition stage is also discussed. We believe that virtualization broadband remote access server (vBRAS) will promote the smart network and intelligent operation development of MAN.
