The invention belongs to the technical field of computers, and particularly relates to a network visual editing and automatic deployment system based on OpenStack, which comprises a front end and a rear end. The front end is used for providing an interface for a user to realize rapid creation of a network topological graph; the rear end is used for importing information analyzed by the network topological graph, creating a virtual network layer and an analog network layer corresponding to the network topological graph on an OpenStack cloud platform, and respectively interconnecting the physical network layer and the analog network layer with the virtual network layer. Compared with the prior art, the virtual-real interconnection of the physical network layer, the virtual network layer andthe analog network layer enables the network environment built by the network topological graph to be more vivid and closer to the effect of an actual network through the virtual-real interconnectionof the physical-virtual-analog three-layer network, and the simulation performance is effectively improved.
