[0002] The traditional virtual twin platform selects the virtual twin technical solution based on the adopted design goals, builds various virtual twin nodes, and networks these twin nodes to form a virtual twin platform.

[0003] If the traditional virtual twin platform construction method only simulates the protocols above the network layer, the constructed virtual twin nodes consume little resources and are more suitable for virtual twins of large-scale networks, but the main disadvantage is that they are not flexible enough. If the network nodes are simulated using hardware simulation, most of the operating details of the network nodes can be twinned, which is very suitable for application scenarios where in-depth analysis of twin nodes is performed. However, network nodes based on hardware simulation consume a lot of resources and are not suitable for the needs of large-scale virtual twin platform construction. It can be seen that the construction method of the traditional virtual twin platform is not flexible enough and it is difficult to meet the needs of large-scale network twins and node operation detail twins at the same time.

[0023] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] The embodiment of the present application provides a method for constructing a hierarchically configurable virtual twin platform, which is executed by a computer device, specifically a computer device such as a terminal or a server, or a terminal and a server. In the embodiment of the present application, Figure 1 As shown, the method includes the following steps.

[0026] S1: Construct a twin network based on the user's twin task and mark the twin node types in the twin network; the twin network includes twin nodes and the topological connection relationship between twin nodes; the twin node types include network nodes based on protocol simulation and network nodes based on hardware simulation.

[0027] S2: Select a configuration strategy from the twin node library according to the twin node type to configure the twin node; the configuration strategy includes a network node configuration strategy based on protocol simulation and a network node configuration strategy based on hardware simulation.

[0028] S3: Build a hierarchically configurable virtual twin platform based on the configured twin nodes.

[0029] In an exemplary embodiment, S2 may be replaced by the following steps.

[0030] When the twin node type is a network node based on protocol simulation, a network node configuration strategy based on protocol simulation is selected from the twin node library, and the twin node is configured through the following steps:

[0031] S21: Perform TCP / IP protocol configuration on the twin node; the TCP / IP protocol configuration includes configuring the IPV4 address, subnet mask and gateway address of the twin node.

[0032] S22: Run the TCP / IP protocol stack so that the twin node has the communication function with the remaining twin nodes.

[0033] S23: On the basis of the communication function, based on the protocol configuration requirements input externally, start the networking simulation protocol corresponding to the networking simulation requirements, and simulate the sending and receiving process and communication mechanism of the networking simulation protocol in accordance with the communication procedures corresponding to the networking simulation protocol; the networking simulation protocol includes RIP protocol, OSPF protocol, ISIS protocol, BGP protocol, route reflection protocol, MPLS protocol, SR protocol and EVPN protocol.

[0034] S24: while running the networking simulation protocol, start a configuration interface corresponding to the networking simulation protocol to receive a configuration command input by a user, and feed back a result of the configuration to the user.

[0035] In an exemplary embodiment, after S24, the step further includes: starting a command simulator according to the protocol configuration requirements to simulate all command functions in the network device command manual.

[0036] In practical applications, the network node configuration strategy based on protocol simulation consists of four parts: basic communication protocol simulation unit, basic data forwarding unit, network networking protocol simulation unit and command simulator. After the protocol simulation, the basic data forwarding unit is used to communicate according to the protocol, such as Figure 2 shown.

[0037] The configuration steps of the network node based on protocol simulation are as follows:

[0038] 1. Start the basic communication protocol simulation unit, implement the protocol configuration of TCP / IP protocol (V4), and configure the IPV4 address, subnet mask, and gateway address on the twin node.

[0039] 2. Start the basic communication program and run the TCP / IP protocol stack so that the twin node has basic communication capabilities with other nodes.

[0040] 3. If network protocol simulation is required based on externally input configuration requirements, the corresponding protocol is activated based on the requirements. Currently supported external network simulation protocols include RIP, OSPF, ISIS, BGP, Route Reflection, MPLS, SR, and EVPN. When externally inputting protocol configuration requirements, the protocol's transmission and reception processes and communication mechanisms are simulated according to the protocol's corresponding communication procedures.

[0041] 4. When running network protocol simulation, the corresponding configuration interface of each protocol is launched simultaneously, providing external users with an interactive interface for each protocol configuration, receiving various configuration commands input by the user, and feeding back the configuration results to the user. The input and output methods and content of the configuration interface are completely simulated in accordance with the configuration process of the corresponding protocol standard.

[0042] 5. Based on the configuration requirements input from the outside, start the command simulator to simulate all the command functions in the network device command manual. By accepting the commands input by the external user, it gives the corresponding output results.

[0043] In an exemplary embodiment, S2 may be replaced by the following steps.

[0044] When the twin node type is a network node based on hardware simulation, a network node configuration strategy based on hardware simulation is selected from the twin node library, and the twin node is configured through the following steps:

[0045] S31: Filter out the virtualized image of the corresponding node from the hardware virtualization node library according to the node parameters generated according to user requirements; the node parameters include the twin node brand and the twin node model.

[0046] S32: According to the twin node model, extract the device firmware file corresponding to the twin node model.

[0047] S33: Load the device firmware file into the virtualized image to virtually load the network device.

[0048] S34: When starting a network node in the network device based on the virtualized image, running and configuring an external access interface of the network node.

[0049] In an exemplary embodiment, S32 may be replaced by the following steps.

[0050] Determine whether the device firmware file has been provided when the user specifies the twin node model.

[0051] If yes, extract the device firmware file provided by the user.

[0052] If not, extract the device firmware file from the firmware file library or third-party resource platform according to the twin node model; if the version number of the device firmware file is inconsistent with the version number required by the twin node model, extract the device firmware file with a version number close to the version number required by the twin node model, and prompt the user whether to use the device firmware file with a similar version number for device simulation.

[0053] In an exemplary embodiment, after S34, the process further includes: using the external access interface to directly provide a normal access mode in an external command line manner, and defining an external access interface that is not directly defined in a conversion manner.

[0054] In actual applications, the configuration steps of the network node based on hardware simulation are as follows:

[0055] 1. Receive configuration commands from external users. If hardware emulation is required to simulate network nodes, enter the hardware emulation network node generation process.

[0056] 2. Based on the node brand, model, and other parameters generated by the user, the system finds the corresponding node virtualization image from the system's built-in "Hardware Virtualization Node Library." This image mainly includes Qume and Dynamips representations.

[0057] 3. Extract the device firmware file corresponding to the network node model generated by the user. If the user provides the device firmware file when specifying the node model, the firmware file provided by the user will be used. If the user does not provide the firmware file, the corresponding firmware file will be found from the built-in firmware file library or third-party resource platform according to the device model to be simulated. If a firmware file with exactly the same version number cannot be found, a firmware file with a similar version number will be searched for, and the user will be prompted whether they agree to use the firmware with a similar version number to simulate the device. If the user agrees, the firmware will continue to be used for simulation. If the user disagrees, a prompt will be given that there is no firmware of the same version for simulation, and the simulation process ends.

[0058] 4. Load the extracted device firmware file into the virtual image, virtually loading the network device. If the user provides a configuration file for the device, the configuration file is imported along with the firmware file, loading the device configuration information. If the user does not provide a configuration file, the device is loaded using the default configuration.

[0059] 5. After the virtual image-based network node is started, run and configure the node's external access interface. The device's network interface directly provides normal access from an external command line. For interfaces that cannot be defined directly, a conversion method is used to define them. For example, define telnet 127.0.0.1 to represent the device's console interface.

[0060] In practical applications, the hierarchical configuration steps in the virtual twin platform constructed in this application are as follows:

[0061] 1. The user issues twin tasks of virtual twin nodes to the twin platform through the management interface.

[0062] 2. Based on the twin tasks assigned by users, the twin platform decomposes the twin tasks into specific twin networks and node twin tasks in each network.

[0063] 3. The twin platform refines the twin tasks of nodes in each network, clarifies the categories of twins that need to be performed on each node and the detailed twin configuration requirements, thereby marking which nodes use protocol simulation twins and which nodes use hardware simulation twins; the refinement process can be manually marked by the user node by node, or automatically identified by the virtual twin platform.

[0064] 4. Depending on the twin node type, start the "configuration of network nodes based on protocol simulation" and "configuration of network nodes based on hardware simulation" processes respectively.

[0065] 5. In the above two configuration processes, the virtual node will be configured in detail on demand based on the configuration information of the network node, such as the configuration information of the router.
