[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.

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0024] In order to make the above-mentioned objects, 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, and can be executed by a computer device such as a terminal or a server alone, or by a terminal and a server together. In the embodiment of the present application, Figure 1 As shown, the method includes the following steps.
[0026] S1: Construct a twin network according to 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 in 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 protocols include 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 configured result 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 communicates 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. According to the configuration requirements input externally, if it is necessary to start the network protocol simulation, start the corresponding network simulation protocol according to the requirements of the network simulation. The currently supported external network simulation protocols include: RIP protocol, OSPF protocol, ISIS protocol, BGP protocol, route reflection protocol, MPLS protocol, SR protocol and EVPN protocol. When the corresponding protocol configuration requirements are input externally, the protocol sending and receiving process and communication mechanism are simulated according to the corresponding communication procedures of the protocol.
[0041] 4. When running the network protocol simulation, the configuration interface corresponding to each protocol is started at the same time, providing the external user with an interactive interface for each protocol configuration, receiving various configuration commands input by the user, and feeding back the configured results to the user. The input and output methods and contents of the configuration interface are completely simulated in accordance with the configuration process of the corresponding protocol standard.
[0042] 5. According to the configuration requirements of external input, start the command simulator to simulate all the command functions in the network device command manual. By accepting the commands input by external users, give 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 virtualized node library according to the node parameters generated according to the user's 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, an external access interface of the network node is run and configured.
[0049] In an exemplary embodiment, S32 may be replaced by the following steps.
[0050] Determine whether a 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 using a conversion method to define an external access interface that is not directly defined.
[0054] In actual applications, the configuration steps of network nodes based on hardware simulation are as follows:
[0055] 1. Receive configuration commands from external users. If the user is required to simulate the network node using hardware simulation, the network node generation process of hardware simulation is entered.
[0056] 2. According to the node brand, model and other parameters generated by the user, find the virtualization image of the corresponding node from the "hardware virtualization node library" built by the system. The image mainly includes the expression forms of Qume and Dynamips.
[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 found, and the user will be prompted whether he agrees 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, it will be prompted 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 and virtually load the network device. If an external user provides a configuration file for the device, when loading the firmware file, the configuration file is imported at the same time to load the device configuration information. If the user does not provide a configuration file, the device is loaded according to the default configuration of the device.
[0059] 5. After the network node based on the virtual image is started, run and configure the external access interface of the node. The network interface of the device directly provides a normal access mode from the external command line. For interfaces that cannot be defined directly, they are defined in a conversion manner. Define telnet 127.0.0.1 to represent the console interface of the device.
[0060] In practical applications, the hierarchical configuration steps in the virtual twin platform constructed in this application are as follows:
[0061] 1. Users issue 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, and marks 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. According to 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 nodes, such as the configuration information of the router.
[0066] Based on the same inventive concept, the embodiment of the present application also provides a hierarchically configurable virtual twin platform construction device for implementing the above-mentioned hierarchically configurable virtual twin platform construction method.
