Abstract: The disclosure provides a method, an apparatus, an electronic device and a storage medium for network topology-based verification. The method comprises: obtaining a network verification request which comprises device change information for a physical network; determining a target network device changed in the physical network using the device change information, and obtaining extended network devices from network devices in each of the hierarchical layers in the physical network, the extended network devices obtained in each of the hierarchical layers corresponding to different providers; constructing an emulated network topology based on the target network device and the extended network devices; and establishing an emulation runtime environment corresponding to the emulated network topology, and performing emulation verification on the emulated network topology based on the emulation runtime environment to obtain an emulation verification result.
