Research SPN technology of 5G transmission network

5G transmission technology is a hot research topic in recent years. As a new architecture of 5G transmission network, SPN (slicing packet network) has the characteristics of being compatible with the PTN (Packet Transport Network) function of the current network, integrating L0~L3 capabilities, and supporting soft and hard isolation slicing. It can better meet the bearer requirements of 5G communication such as ultra-large bandwidth, ultra-low delay, and so on; improve the problems of insufficient openness and scalability of traditional transmission networks. This paper research the network architecture, the key technologies, and technical characteristics of SPN, and the technical requirements of network slicing on transmission network. Based on the research, implementation method and scheme of connecting the exclusive hard slicing and the shared hard slicing to the 5G network in the SPN slicing bearing are further analyzed. Finally, provide a pilot networking scheme of the SPN transmission network.
