Method and apparatus to create a virtualized replica of a computer network

Abstract

Disclosed herein are system, method, and computer program product aspects for generating a virtual replica of a physical network. An aspect operates by receiving, from a network management system (NMS), a request to generate a network digital twin (network-DT) instance corresponding to a physical network that includes a plurality of physical network devices, where the request includes link connectivity information corresponding to the physical network and a respective plurality of device characteristics corresponding to each of the plurality of physical network devices. A plurality of device digital twin (device-DT) instances are generated, each corresponding to a respective physical network device of the plurality of physical network devices, where each device-DT instance of the plurality of device-DT instances is generated based on the respective plurality of device characteristics corresponding to the respective physical network device. The network-DT instance is generated based on the plurality of device-DT instances and the link connectivity information.
