As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," 8230; \8230 "; when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

The inventor of the embodiment of the present disclosure finds that, in the prior art, when a network topology is drawn, each node needs to be drawn separately, where the drawn node includes information such as a name of a configured node, an operating system, a Central Processing Unit (CPU) core number, a memory size, a disk size, a network configuration, and an acquisition item configuration. When a large-scale virtual node network environment is needed, the number of nodes to be drawn can even reach millions of orders, and if the existing network topology drawing mode is adopted for drawing, a large amount of labor and time are consumed.
In view of the above, in a first aspect, referring to fig. 1, an embodiment of the present disclosure provides a method for generating a network topology, where the method includes:
in step S100, determining the number of area topology templates with different structures in each area topology according to first configuration information of a plurality of area topologies, where the area topology templates define a general topology structure;
