This paper presents a digital twin platform towards automatic and intelligent management for data center networks: NetGraph. It builds a virtual image of the physical network, which comprises the entire network elements and simplifies the workflows of network service management. NetGraph redefines network operation (including maintenance) model by integrating four functional blocks: unified digital twin model management, automatic configuration deployment and translation, Inventory search, and network elements validation.

NetGraph has been deployed in Huawei's data center networks and served more than fifty thousand devices along with millions of network connectivity information (e.g., links and terminations points). Statistics in real network scenarios show that NetGraph has a wide coverage of network models and supports multiple functions.
