[Abstract] As the basic network, 5G transport network is considered to face five major challenges, such as wide bandwidth, low delay, high-precision synchronization, flexible connection, and network slicing. In this paper, a layer network slicing architecture for 5G transport network is proposed, and some key technologies including soft-defined network (SDN) control plane slicing, flexible Ethernet (FlexE) -based data plane hard slicing, transport device slicing and virtualization, and E2E slicing orchestration for 5G services are studies.
