[0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a method, device, electronic device, and storage medium for implementing a virtualized network. Background Art

[0002] Currently, network simulation experiments for scenarios like shooting range event drills and attack simulations require the construction of a corresponding computer network. By utilizing virtualization simulation technology, the required computer network can be converted into a corresponding network model, and then the network simulation experiment can be conducted using computer software. Furthermore, virtualization simulation technology can quickly obtain the required parameter information by calculating the relevant network model, thereby improving the simulation efficiency of network simulation experiments.

[0003] However, when conducting a network simulation experiment in existing network simulators, one must first manually draw a network topology diagram within the simulator's interface and manually configure each device in the topology diagram before conducting the network simulation experiment. Switching to another network simulation experiment requires the same topology drawing and manual configuration process. This process is time-consuming and inefficient when conducting multiple network simulation experiments. Summary of the Invention

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] As mentioned above, the existing network simulation simulator can only conduct a single network simulation experiment at a time. Each time you switch to another network simulation experiment, you need to go through the topology drawing and manual configuration process. If you want to use the network simulation simulator to conduct multiple network simulation experiments, it will take a lot of time and the efficiency is poor.

[0033] Based on this, the inventive concept of the present invention is to transfer the topology drawing and manual configuration process to the outside of the network simulation simulator, draw the topology map in the local system and manually configure each device in the topology map to form a network topology map that can be used for network simulation, and then call the instance interface of the network simulation simulator, and let the network simulation simulator perform a network simulation experiment on the network topology map, and output the network simulation experiment results to the local system. In this way, when multiple network simulation experiments are required, these topology maps can be drawn and configured in advance. When switching between different network simulation experiments, only the instance interface of the network simulation simulator needs to be called to quickly obtain the simulation experiment results, thereby improving the efficiency of network simulation.

[0034] The specific implementation of the above concept is described below.

[0035] Please refer to Figure 1 , an embodiment of the present invention provides a method for implementing a virtualized network, the method comprising:

[0036] Step 100: Obtain a file to be virtualized in a target format; the file to be virtualized stores the corresponding field content configured for each device in the network topology diagram to be virtualized; the target format is the data format corresponding to when the target network simulation simulator draws and stores the network topology diagram;

[0037] Step 102: calling the instance interface of the target network simulation simulator based on the file to be virtualized, and obtaining a network simulation experiment topology map generated by the target network simulation simulator using the file to be virtualized.

[0038] In an embodiment of the present invention, by transferring the topology drawing process and the device configuration process from the inside of the target network simulation simulator to the outside, a corresponding file to be virtualized is generated for the desired virtualized network topology. It is only necessary to make the format of the file to be virtualized the same as the data format when the target network simulation simulator draws and stores the network topology. In this way, by calling the instance interface of the target network simulation simulator, the target network simulation simulator can identify and parse the file to be virtualized, and then generate a network simulation experiment topology corresponding to the desired virtualized network topology. It can be seen that in this solution, there is no need to perform the topology drawing process and the manual configuration process in the network simulation simulator. Even if multiple network simulation experiments are required, the network simulation experiment topology can be quickly obtained by calling the instance interface of the network simulation simulator, thereby improving the efficiency of the network simulation experiment.

[0039] Described below Figure 1 How to perform the steps shown.

[0040] First, for step 100, obtain the target format of the file to be virtualized; the file to be virtualized stores the corresponding field content configured for each device in the network topology diagram to be virtualized; the target format is the corresponding data format when the target network simulation simulator draws and stores the network topology diagram.

[0041] In an embodiment of the present invention, the file to be virtualized can be generated from the network topology diagram to be virtualized, or the file to be virtualized can be generated by directly editing the data content. When the file to be virtualized is generated from the network topology diagram to be virtualized, specifically: in the local system interface, the network topology diagram and the field content of the configured device can be directly drawn, or the field content of the configured device can be configured in the local system interface after the drawn network topology diagram is imported, or the field content of the configured device can be configured after the drawn network topology diagram is imported and configured, and then the local system stores the drawn and configured network topology diagram as the file to be virtualized in the target format.

[0042] Network topology Figure 1 It is generally used for shooting range event drills, attack event simulations, etc. For example, the network topology diagram of the **intranet penetration shooting range, the network topology diagram of the **digital currency exchange intrusion incident, the network topology diagram of the **attack shooting range, etc.

[0043] Virtualizing each device in a network topology diagram involves creating a virtual machine for each device. In embodiments of the present invention, to utilize the network topology diagram to virtualize each device in the diagram, it is necessary to configure corresponding field content for each device in the diagram. The corresponding field content configured for each device in the diagram is configured according to the field information required for virtualization, and the field content includes at least the virtual machine information corresponding to the device when virtualized.

[0044] The virtual machine information may include: network bridge information, virtual machine template, virtual machine version, virtual machine startup parameters and virtual image. Based on this virtual machine information, a virtual machine can be cloned for the device, so this virtual machine information must be configured in the device.

[0045] In addition to the above-mentioned virtual machine information, in order to enable the network simulation simulator to virtualize each device in the network topology diagram and output the network simulation experiment topology diagram, in an embodiment of the present invention, the field content of the device configuration may also include: device name, device ID, device type, device ID in the topology diagram, memory, Arch operating system version, device location, device icon, device network status, number of CPUs and at least one of bridge information.

[0046] In summary, the field contents of the device configuration may include the following Table 1:

[0047] Table 1:

[0048]

[0049] The bridge information may further include: device port name, device port number, bridge name, and bridge number.

[0050] After the network topology diagram to be virtualized is obtained, it can be stored as a file to be virtualized in a target format.

[0051] In an embodiment of the present invention, common network simulation simulators include eNSP, EVE-NG, GNS3, Cisco Packet Tracer, H3C HCL, etc. Different network simulation simulators have different data formats when drawing and storing network topology maps. In order to enable the network simulation simulator to simulate the externally drawn network topology map, it is necessary to store the data format of the externally drawn network topology map as the data format of the network simulation simulator to be called.

[0052] Considering that the EVE-NG network emulator can not only simulate network devices but also run virtual machines of all image types, theoretically, as long as the virtual disk format of the virtual machine can be converted to qcow2, the virtual machine can run on EVE-NG. Therefore, in the embodiment of the present invention, the target network emulator can be the EVE-NG network emulator.

[0053] EVE-NG is currently the most powerful network emulator for the X86 instruction set. It utilizes a client / server architecture, with the environment packaged on the GNU-Linux distribution Ubuntu as the server. The machine conducting the network simulation experiment is the client. Once the client connects to the server via the web, the EVE-NG experimental environment and topology are presented in a web-based format. Once the virtual image is uploaded and the network topology diagram is available, network simulation experiments can be conducted.

[0054] Correspondingly, when the target network simulation simulator is an EVE-NG network simulation simulator, the corresponding data format when the target network simulation simulator draws and stores the network topology diagram is the XML format.

[0055] When exporting a network topology map to a file, it is typically stored in JSON format. This means that the device information in the network topology map is stored as a JSON string. Specifically, the JSON string storing the device information in the network topology map needs to be converted to XML format to obtain the XML file to be virtualized.

[0056] For example, for a device in the network topology to be virtualized, the content in the XML file to be virtualized can be:

[0057] <nodes>

[0058] <nodename="Win"id="1178"type="qemu"uuid="b6a4c514-e871-47fe-af49-7f5209c3813b"top="395"

[0059] template="win"ram="4096" qemu_version="4.1.0" qemu_options="-machine type="pc,accel="kvm-cpu" host,+pcid,+kvm_pv_unhalt,+kvm_pv_eoi,hv_spinlocks=0x1fff,hv_vapic,hv_time,hv_reset,hv_vpindex,hv_runtime,

[0060] -vga std-usbdevice tablet-boot order=cd-drive file= / opt / qemu / share / qemu / virtio-win-

[0064] <interface name="E0"id="0"type="ethernet"network_id="1082" / >

[0065]

[0066] As you can see, the XML file contains all the device configuration information, allowing the target network simulator to accurately virtualize the device based on this XML file. Furthermore, if you need to modify the device configuration, you can do so directly on the local system or by modifying the XML file. This makes changes convenient and also facilitates device maintenance.

[0067] Step 102: calling the instance interface of the target network simulation simulator based on the file to be virtualized, and obtaining a network simulation experiment topology map generated by the target network simulation simulator using the file to be virtualized.

[0068] By calling the instance interface of the target network simulation simulator, the file to be virtualized is input into the target network simulation simulator. Since the format of the file to be virtualized is the same as the data format of the network topology map drawn and stored by the target network simulation simulator, the target network simulation simulator can parse and identify the field content required for virtualization of each device in the network topology map to be virtualized.

[0069] Specifically, in an embodiment of the present invention, the target network simulation simulator uses the file to be virtualized to generate a network simulation experiment topology diagram, which may include: determining the virtual image of each device based on the file to be virtualized; for each virtual image of a device, obtaining the virtual image of the device in the virtual image library, and virtualizing the device using the obtained virtual image and other virtual machine information; generating a network simulation experiment topology diagram for each virtualized device based on the other field contents of each device in the file to be virtualized.

[0070] For example, the device fields in the preceding XML file contain the following bridge information: device port name "E0", device port number "0", bridge name "ethernet", and bridge number "1082". The device's virtual image is "win-7-lite-u4", which can be obtained from the virtual image library. The device can be virtualized using the virtual machine template, virtual machine version, virtual machine startup parameters, and the "win-7-lite-u4" virtual image. The virtualized device is a device instance that emulates the resources and functions of the corresponding physical device.

[0071] After all devices in the network topology are virtualized, since the field content of the device also includes information such as the location of the device in the network topology, a network simulation experiment topology corresponding to the network topology can be generated based on these field contents.

[0072] Among them, the virtual images in the virtual image library of the target network simulation simulator are pre-made. If the virtual image of the device does not exist in the virtual image library, a virtual image of the device needs to be made and stored in the virtual image library, so that the virtual images in the virtual image library have a wider coverage, can meet the virtualization of different devices, and improve the efficiency of network simulation experiments.

[0073] After generating the network simulation experiment topology diagram, the target network simulation simulator can output it to the local system, and then the network simulation experiment topology diagram can be displayed in the local system.

[0074] Furthermore, the network simulation experiment topology map generated by the target network simulation simulator can also be stored in the local system; when it is necessary to switch to the network simulation experiment topology map corresponding to other network topology maps, if the network simulation experiment topology map corresponding to the other network topology map is stored in the local system, it can be called directly from the local system.

[0075] In the prior art, when switching to other network simulation experiments, not only is it necessary to draw a topology map and manually configure the process in the network simulation simulator, but it is also necessary to launch the current network topology interface, and one account cannot be logged in to multiple terminals at the same time. In this embodiment, not only can it switch quickly, but it can also support multiple terminals to log in to one account at the same time, thereby improving the user experience.

[0076] For example, the local system stores the network simulation experiment topology map of the **intranet penetration target range, the network simulation experiment topology map of the **digital currency exchange intrusion incident, and the network simulation experiment topology map of the **attack target range. If the network simulation experiment is completed for the network simulation experiment topology map of the **intranet penetration target range, and it is necessary to perform a network simulation experiment on the network simulation experiment topology map of the **digital currency exchange intrusion incident, the network simulation experiment topology map of the **digital currency exchange intrusion incident stored can be directly called from the local system, and then the network simulation experiment of the **digital currency exchange intrusion incident can be performed.

[0077] It should be noted that when performing network simulation on the network simulation experiment topology diagram, it is necessary to call the interface of the target network simulation simulator to perform simulation by the target network simulation simulator.
