Abstract: With the advent of the 5G era, the rapid deployment capabilities of network services and the requirements for network operation and maintenance capabilities pose new challenges to network management. On the one hand, the network is undergoing a network function virtualization transformation, and slicing and microservices complicate the network. On the other hand, network managers need a simpler and automated tool set to support on-demand, real-time, and flexible network services. This article analyzes the current difficulties faced by network management and the reasons for the difficulties, and proposes a research framework for network self-management to provide references for further research. 

Key words: network management, autonomous driving network, intelligent network operation and maintenance
