[0001] The embodiments of the present invention relate to the field of computer networks, and in particular to an Ethernet interface switching method, device, equipment, medium and product. Background Art

[0002] As a new communication protocol, Ethernet bus is increasingly used in the process of automobile intelligence due to its advantages in transmission rate and transmission bandwidth.

[0003] In bench testing and verification, there is a very light demand for Ethernet simulation development. For Ethernet simulation, it is usually at the signal level, and signal-level simulation may not meet the verification requirements for a functional system level, especially for controllers such as the instrument center console installed in the vehicle. The above controller involves human-computer interaction, and system-level verification needs to cover human-computer interaction testing, such as the instrument's sound reminder, text pop-up window, and the function switch light of the center console. In the above situation, connecting to a real center console instrument controller and the tester's direct operation can meet the functional system testing requirements, but the disadvantage of the above situation is that it is difficult to achieve automated testing.

At this time, it is necessary to disconnect the real central control instrument controller node and connect to the simulated central control instrument controller node. The main method used to connect the instrument controller node is: manually disconnect the wiring between the central control instrument controller and the opponent controller, and then reconnect the wiring between the opponent controller and the central control instrument controller to the board card of the simulation node, that is, the test bench needs to be rewired.

[0039] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme 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 only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0040] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0041] When introducing the solution provided by the embodiment of the present invention, the application scenario can be illustrated first. The solution provided by the embodiment of the present invention can be applied to any scenario that requires testing of the Ethernet interface, that is, as long as the switching of the Ethernet port is involved, the solution provided by the embodiment of the present invention can be used to handle it.

[0042] Before performing the Ethernet port switching operation based on the solution provided in the embodiment of the present invention, the Ethernet board and the ports on the Ethernet board may be introduced first.

[0043] like Figure 1 As shown, the Ethernet board has at least two ports, and the ports are connected to the domain controller through an Ethernet interface. Ethernet channels are configured for the two ports, and the two ports are in the same Ethernet channel, so that the domain controllers corresponding to the two ports can obtain communication message data and analyze and process the communication message data during the communication process to determine the test result data.

[0044] Among them, the port is located on the Ethernet board, and a common port type may be an RJ45 port. The domain controller may be a server for managing a computer network. For example, in a car, the domain controller may be a cockpit domain controller or an intelligent driving domain controller. The Ethernet interface may be a key component for a domain controller to communicate with other domain controllers. For example, a failure in the Ethernet interface may cause the signal between the domain controller and the network to be interrupted. The wiring harness connection may be the use of a cable harness to achieve a physical connection between the port and the domain controller. The wiring harness connection may use twisted pair or fiber optic cable. The communication message may be the encapsulation form of data when it is transmitted in the network, and the communication message exists in the form of a signal during the communication interaction process.

[0045] Specifically, the port of the Ethernet board and the interface of the domain controller are connected through a twisted pair or optical fiber cable. The port of the Ethernet board is located in the same Ethernet channel. When the two domain controllers interact, the communication message between the two domain controllers can be obtained, the communication message data can be analyzed and processed, and the test result data can be determined. By analyzing and processing the message, it can be determined whether the communication interaction between the two domain controllers is in line with reality.

[0046] For example, in a test bench of the intelligent driving function of a certain vehicle model, when testing the interactive function of the intelligent driving function, it is necessary to connect the central control screen of the cockpit domain controller to directly verify the setting of the function in the central control screen and the display of the function on the central control screen. At this time, it is necessary to connect the real nodes of the intelligent driving domain controller corresponding to the intelligent driving function and the cockpit domain controller corresponding to the cockpit. Connect the port of the Ethernet board to the interface corresponding to the cockpit domain controller and the interface corresponding to the intelligent driving domain controller through a twisted pair cable, obtain the communication message in the communication interaction process between the cockpit domain controller and the intelligent driving domain controller, analyze and process the message to determine the test result between the cockpit domain controller and the intelligent driving domain controller.

[0047] According to Figure 1 After the harness connection is completed using the method shown, when two real domain controllers need to be connected at the same time during testing, and only the communication messages between the two domain controllers need to be monitored, Ethernet port 1 and Ethernet port 2 can be activated at the same time in the network configuration of the Ethernet board, and the Ethernet channel containing these two ports can be associated with the Ethernet channel of the monitoring software, so that the communication messages between the two domain controllers can be monitored, and the communication messages can be parsed after loading the arxml file.

[0048] Embodiment 1

[0049] Figure 2 This is a flow chart of an Ethernet interface switching method provided in the first embodiment of the present invention. This embodiment is applicable to any scenario where Ethernet ports need to be switched. The method can be executed by an Ethernet interface switching device, which can be implemented in hardware / software, and can be integrated in an electronic device. Optionally, the electronic device can be a mobile terminal or a PC. Figure 2 As shown, an Ethernet interface switching method disclosed in this embodiment may include:

[0050] S110. In response to the domain controller switching operation, determine a target domain controller to be switched, and create a virtual domain controller corresponding to the target domain controller.

[0051] Among them, the user can trigger the corresponding program or a certain functional control to issue an instruction to switch the controller, and the above operation can be used as a switching operation. When a domain controller switching operation is detected, a domain controller switching instruction can be issued to enable the server or client to respond to the domain controller switching operation. For example, in order to test the requirements, one of the real domain controllers needs to be switched to a virtual domain controller, and the domain controller switching operation can be triggered so that the server or client responds to the domain controller switching operation. The domain controller to be switched is used as the target domain controller. The target domain controller can be a real domain controller or a virtual domain controller, and its specific type can be set according to actual needs. If the target domain controller is a real domain controller, it can be converted into a virtual domain controller for simulation. The functions of the virtual domain controller are the same as those of the target domain controller. For testing, the virtual domain controller needs to be connected to the domain controller to be switched, and the communication messages between the two are analyzed.

[0052] Specifically, when the test requires switching of the domain controller, the domain controller to be switched is determined, and the corresponding virtual domain controller is connected to complete the test.

[0053] For example, in a test bench of the intelligent driving function of a certain vehicle model, the main function of the intelligent driving is in the intelligent driving domain controller, and the cockpit domain controller mainly implements the interaction with the intelligent driving function, such as function setting, function display, etc. When testing the main function, the signal of the interaction between the cockpit domain controller and the intelligent driving domain controller can be simulated to facilitate automated testing. At this time, the intelligent driving domain controller and the simulated cockpit domain controller need to be connected.

[0054] S120: Set the port to which the Ethernet interface of the target domain controller is connected to a disabled state, and configure operating parameters for the virtual domain controller so that the virtual domain controller and the unswitched domain controller are located in the same Ethernet channel based on the operating parameters.

[0055] The disabled state may be to disable a function, for example, a port is disabled, and the function corresponding to the port is disabled. Configuring the operation parameters may be to set various parameters of the virtual domain controller, for example, to select a corresponding port for the virtual domain controller, so that the ports of the virtual domain controller and the unswitched domain controller are located on the same Ethernet board, that is, the two domain controllers are located in the same Ethernet channel.

[0056] Specifically, the port corresponding to the domain controller to be switched is set to a disabled state, and a corresponding port is selected for the virtual domain controller corresponding to the domain controller to be switched so that the virtual domain controller and the unswitched domain controller are located in the same Ethernet channel.

[0057] For example, Figure 3As shown, the Ethernet port 1 in the Ethernet board connected to the Ethernet interface A of the cockpit domain controller is disabled, and the cockpit domain controller can be powered off at the same time, the cockpit domain controller simulation node is turned on, and the Ethernet port 2 in the Ethernet board connected to the Ethernet port B of the intelligent driving domain controller is activated, and the Ethernet channel containing Ethernet port 2 is configured as the hardware channel of the cockpit domain controller simulation node. In this way, the connection between the real domain controller and the cockpit domain controller simulation node can be realized.

[0058] It should be noted that in the port configuration of the Ethernet board, the two ports to be used are configured in the form of a switch, and the two ports to be tested can be configured in one Ethernet channel to facilitate subsequent data monitoring and data simulation.

[0059] See also Figure 3 Continuing with the example explanation, when it is necessary to switch one of the real domain controllers to a simulated domain controller, for example, it is necessary to switch the real domain controller A node to the simulated domain controller A node, then it is necessary to disable Ethernet port 1 connected to Ethernet interface A of the real domain controller A in the network configuration of the Ethernet board, and add a virtual simulation node domain controller A in the Ethernet simulation software. The hardware channel associated with this simulation node includes 2 Ethernet channels on the Ethernet end, and Ethernet port 2 connected to Ethernet interface B of domain controller B remains activated. After running the node simulation, the real domain controller B and the simulated node of domain controller A can communicate and interact, and this switching process does not require additional rack rewiring work.

[0060] The technical solution of the embodiment of the present invention reduces the complexity of manual configuration and improves work efficiency by responding to a domain controller switching operation, determining a target domain controller to be switched, and creating a virtual domain controller corresponding to the target domain controller; setting the port connected to the Ethernet interface of the target domain controller to a disabled state, and configuring operating parameters for the virtual domain controller, so that the virtual domain controller and the unswitched domain controller are located in the same Ethernet channel based on the operating parameters, connecting all lines in advance, and quickly switching the target domain controller and the virtual domain controller without changing the line during the test process, omitting the step of changing the line of the test bench, achieving the effect of test automation, and thus improving test efficiency.

[0061] Embodiment 2

[0062] Figure 4 It is a flowchart of an Ethernet interface switching method provided in Example 2 of the present invention. Based on the above implementation, the switching process of the target domain controller and the virtual domain controller is further refined. The specific implementation method can be found in the detailed description of this embodiment, wherein the technical terms that are the same as or corresponding to the above embodiment are not repeated in this embodiment.

[0063] like Figure 4 As shown, an Ethernet interface switching method disclosed in this embodiment may include:

[0064] S210. In response to a domain controller switching operation, send a domain controller creation instruction to a target simulation model to create a virtual domain controller corresponding to the target domain controller in the target simulation model.

[0065] Among them, the target simulation model can be a pre-established model for generating a simulated domain controller. Specifically, when a domain controller switching operation is detected, a creation instruction for creating a virtual domain controller can be generated and sent to the target simulation model. When the target simulation model receives the domain controller creation instruction, a virtual domain controller corresponding to the target domain controller can be created in the target simulation model. The virtual domain controller mentioned above can be used as a simulated domain controller. It should be noted that the functions performed by the virtual domain controller are the same as those performed by the target domain controller. In other words, except for the different forms of existence, the other corresponding functions of the virtual domain controller and the target controller are the same.

[0066] S220: Set the port to which the Ethernet interface of the target domain controller is connected to a disabled state, and configure operating parameters for the virtual domain controller so that the virtual domain controller and the unswitched domain controller are located in the same Ethernet channel based on the operating parameters.

[0067] S230: When receiving a request to switch back to the target domain controller, activate the port corresponding to the target domain controller and update the configuration data of the port.

[0068] Activation may be to enable a function, for example, a port is activated, and the function corresponding to the port is enabled. Configuration data may be data that the port is in a working state and is in the same Ethernet channel as the port corresponding to the unswitched domain controller, for example, activating the port corresponding to the target domain controller so that it is in the same Ethernet channel as the port corresponding to the unswitched domain controller.

[0069] Specifically, after the simulation test is completed, the target domain controller corresponding to the virtual domain controller needs to be reconnected to the unswitched domain controller. At this time, the port of the target domain controller is activated and the data of the port is updated.

[0070] For example, Figure 5As shown, after the simulation test of the intelligent driving domain controller and the cockpit virtual domain controller is completed, it is necessary to reconnect the real nodes of the intelligent driving domain controller and the cockpit domain controller. Activate Ethernet port 1 in the Ethernet board that is connected to Ethernet interface A of the cockpit domain controller, keep Ethernet port 2 of the Ethernet board activated, and configure Ethernet port 1 and Ethernet port 2 as Switch connections. Configure them in the same Ethernet channel. This Ethernet channel can be used as a hardware channel for communication monitoring to monitor the interaction signals between the cockpit domain controller and the intelligent driving domain controller. In this way, the intelligent driving domain controller can be switched to connect to the real node of the cockpit domain controller without changing the test bench wiring harness connection.

[0071] Optionally, the configuration data at least includes data indicating that the port is in a working state and is in the same Ethernet channel as another port. The port is in a normal working state, and it is in the same Ethernet channel as another port.

[0072] For example, when it is necessary to switch domain controller A back to the real node, the disabled Ethernet port 1 needs to be activated again, and the simulated domain controller A node needs to be disabled in the simulation model. At this time, it is possible to quickly switch back to the communication and interaction mode between the two real domain controller nodes.

[0073] S240: Send an instruction to stop using the virtual domain controller to the target simulation model, so that the target simulation model adjusts the current state of the virtual domain controller to a disabled state.

[0074] It can be understood that when switching back to the target source controller, an instruction to stop using the virtual domain controller can be sent to the target simulation model. After receiving the instruction to stop using the virtual domain controller, the target simulation model can adjust the current state of the virtual domain controller from the use state to the disabled state, so that the subsequent virtual domain controller no longer receives new data processing requests or transmits data.

[0075] Based on the above technical solution, the method also includes: when the number of the ports includes at least three, the method also includes: determining the target number located in the same Ethernet channel according to the bandwidth information; configuring corresponding connection data for the ports consistent with the target number, so as to enable the domain controller and the corresponding port to be connected by a wiring harness through the Ethernet interface based on the connection data, wherein the connection data also includes Ethernet channel data.

[0076] It can be understood that the solution provided by the embodiment of the present invention can be expanded into a mode of multiple domain controllers. In this case, it is only necessary to increase the number of ports of the Ethernet channel. That is, if there are n domain controllers, they are connected to n Ethernet ports accordingly, and the n Ethernet ports are configured in the same Ethernet channel. Accordingly, switching between one or more real domain controllers and simulated domain controllers can be achieved under the condition that the bandwidth is met.

[0077] It should also be noted that the target number of Ethernet ports that can be configured at most can be determined based on the bandwidth information and the communication bandwidth corresponding to each Ethernet port. Connection data can be configured for ports that are consistent with the target number, so that the domain controller and the corresponding port are connected by wire harness through the Ethernet interface based on the connection data.

[0078] The technical solution of the embodiment of the present invention reduces the complexity of manual configuration and improves work efficiency by responding to a domain controller switching operation, determining a target domain controller to be switched, and creating a virtual domain controller corresponding to the target domain controller; setting the port connected to the Ethernet interface of the target domain controller to a disabled state, and configuring operating parameters for the virtual domain controller, so that the virtual domain controller and the unswitched domain controller are located in the same Ethernet channel based on the operating parameters, connecting all lines in advance, and quickly switching the target domain controller and the virtual domain controller without changing the line during the test process, omitting the step of changing the line of the test bench, achieving the effect of test automation, and thus improving test efficiency.

[0079] Embodiment 3

[0080] As an alternative embodiment to the above embodiment, the technical solution provided by the embodiment of the present invention is explained with a specific example. Figure 1 The technical solution provided by the embodiment of the present invention can use two ports in the Ethernet board at the same time, port 1 and port 2. The two ports are respectively connected to the Ethernet interfaces of two real domain controllers by wire harnesses, that is, Ethernet port 1 is connected to Ethernet interface A of domain controller A, and Ethernet port 2 is connected to Ethernet interface B of domain controller B. In the port configuration of the Ethernet board, the two used ports are configured in the form of a Switch, which is implemented by an automated script, and the two ports are configured in an Ethernet channel to facilitate subsequent data monitoring and data simulation.

[0081] Since the switch connection of the port in this embodiment is implemented through software configuration, when software configuration cannot be implemented, it can also be implemented in the form of a real switch.

[0082] After completing the harness connection, when two real domain controllers need to be connected at the same time during the test, and only the communication messages between the two domain controllers need to be monitored, Ethernet port 1 and Ethernet port 2 can be activated at the same time in the network configuration of the Ethernet board, and the Ethernet channel containing these two ports can be associated with the Ethernet channel of the monitoring software, that is, the communication messages between the two domain controllers can be monitored, and the communication messages can be parsed after loading the arxml file. The activation or deactivation of the port is realized through software configuration. If the software configuration cannot be realized, it can also be realized by controlling the connection and disconnection of the port through a relay.

[0083] like Figure 6 As shown in the figure, when one of the real controllers needs to be switched to a simulated controller, for example, the real domain controller A node needs to be switched to the simulated domain controller A node, then the Ethernet port 1 connected to the Ethernet interface A of the real domain controller A needs to be disabled in the network configuration of the Ethernet board, and a virtual simulation node domain controller A needs to be added in the Ethernet simulation software. The hardware channel associated with this simulation node is a two-port Ethernet channel including the Ethernet end, and the Ethernet port 2 connected to the Ethernet interface B of the domain controller B remains activated. At this time, after running the node simulation, the real domain controller B and the simulated node of the domain controller A can realize communication and interaction, and this switching process does not require additional bench rewiring work.

[0084] like Figure 7 As shown, when it is necessary to switch domain controller A back to the real node, the disabled Ethernet port 1 needs to be activated again, and the simulated domain controller A node needs to be disabled in the simulation model. At this time, it is possible to quickly switch back to the communication and interaction mode between the two real domain controller nodes.

[0085] Similarly, this method can also be used for switching between real and simulated nodes of domain controller node B. This solution can also be expanded to a mode with multiple domain controllers. In this case, it is only necessary to increase the number of ports of the Ethernet channel. That is, if there are n domain controllers, they are connected to n Ethernet ports accordingly, and the n Ethernet ports are configured in the same Ethernet channel. Accordingly, the switching between one or more real domain controller nodes and simulated domain controller nodes can be realized.

[0086] The technical solution of this embodiment connects the ports through Switch, and realizes the quick switching of real Ethernet nodes and simulated Ethernet nodes by means of port configuration, and realizes the switching of real nodes and simulated nodes in the Ethernet network in the software configuration conveniently and quickly, without adding additional re-line workload; connects the ports through Switch, and realizes the signal monitoring of real Ethernet nodes by means of port configuration, and can realize the monitoring of communication between two controllers whether it is connected to real nodes or simulated nodes, without adding additional re-line workload. This connection method can be expanded to the connection of many Ethernet nodes within the range allowed by the Ethernet bandwidth, and the convenient switching of real nodes and simulated nodes of any Ethernet node can be realized by means of port configuration. The technical solution of this embodiment reduces the re-line workload of the test bench, speeds up the switching speed of the test environment, and improves the test efficiency. At the same time, the switching of nodes can be realized by automated scripts, which is conducive to the implementation of automated testing and improves test efficiency.
