Abstract (in Japanese) (See Japanese page) 
(in English) In the DX era, to quickly service in is required as business needs change. The current network design and operation relies on the know-how of experts and often does by manual work, so there is a limit to speeding up. Against this background, we have studied on an automatic network design that uses coded and reusable customer design policies and expert know-how and a network pre-validation that confirms the validity of setting changes beforehand. This paper proposes the network pre-validation technology that specifically aims to avoid human error during network construction work. Based on the configuration of the real network, we automatically construct a virtual network for validation (network digital twin) with the same routing functionality as the real network in a container environment using virtual routers. We simulate a large-scale network by building network digital twin across multiple servers. After that, we change settings on the network digital twin, and confirm the impact on routing, such as communication status and routes between ends. We confirmed that our technology can validate configuration changes on a large-scale network of five hundred devices in a sufficiently short amount of time.
