[0052] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0053] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0054] Specifically, in the automotive field, time-sensitive networks based on in-vehicle Ethernet have gradually become a research focus. Compared with the traditional controller area network (CAN) as an Ethernet bus, time-sensitive networks not only guarantee the network bandwidth in data transmission, but also guarantee the timing, delay and reliability of data transmission. Therefore, in order to support the planning of future vehicle body electronic and electrical architecture, it is necessary to quickly build and complete the verification of time-sensitive networks. For the verification of time-sensitive networks, at least the following should be included: a traffic generation module, which is used to generate and send data packets according to demand; an end node device with time-sensitive network characteristics, which is used to participate in the time synchronization and data scheduling of the time-sensitive network; a bridge node device with time-sensitive network characteristics, which is used to participate in the time synchronization, data scheduling, data forwarding, etc. of the time-sensitive network; a traffic analysis module, which is used to capture data packets and analyze traffic scheduling results. Through the combination of the above modules and devices, the verification of time synchronization, gate scheduling, frame preemption, frame replication and elimination, frame filtering and other functions defined in the time-sensitive network protocol is completed. However, due to the different functions to be implemented by the end node and the bridge node, two different devices are usually required to implement the functions of the end node and the bridge node, and relevant personnel need to determine the selection of the end node and the bridge node according to the scene requirements, that is, when performing time-sensitive network verification, a variety of different devices need to be used, which is very likely to cause a waste of manpower and material resources, and is time-consuming, and is not convenient for fast and accurate verification of time-sensitive networks in different scenarios. Therefore, in view of the above problems, the time-sensitive network verification device provided by the present disclosure is explained through one or more of the following embodiments.

[0055] Specifically, time synchronization is mainly achieved based on the defined master clock and slave clock. The data of the master clock is transmitted through the master clock interface, and the data of the slave clock is transmitted through the slave clock interface. The master clock refers to the generated time data as the time source, and the slave clock is synchronized with the current time data generated by the master clock.

[0056] Specifically, the time-sensitive network in the embodiments of the present disclosure may be a standard defined by the Institute of Electrical and Electronics Engineers (IEEE) Time Sensitive Network (TSN), for example, may be an IEEE 802.1 protocol.

[0057] Figure 1 The schematic diagram is a structural diagram of a time-sensitive network authentication device provided in an embodiment of the present disclosure. The authentication device 100 includes an integration module 110 and a switching module 120 .

[0058] It can be understood that the integrated module 110 can specifically be an integrated circuit or an integrated chip (System on Chip, SoC), in which all or most components of a computer or other electronic system are integrated, including a central processing unit (CPU), memory, input / output ports and secondary storage, and usually also including other components such as a radio modem and a graphics processing unit (GPU). The specific selection of the integrated module is not limited, and it only needs to have the above-mentioned functions.

[0059] It is understandable that the switching module 120 can specifically be an Ethernet switch (Ethernet Switch), also known as a switching hub, a bridging hub, or a bridge, which is a type of network hardware that receives and forwards data to a destination device through packet switching, thereby connecting devices on a computer network.

[0060] The integrated module 110 includes a first processor 111 and an Ethernet controller 112 . The Ethernet controller 112 includes an Ethernet interface 113 . The first processor 111 and the Ethernet controller 112 are connected via a device interface, wherein the Ethernet interface has the attribute of a time-sensitive network.

[0061] Optionally, the first processor is used to configure the integrated module, and is also used to generate, receive, save and send data.

[0062] It can be understood that the integrated module 110 includes a first processor 111 and an Ethernet controller 112; the first processor 111 can be a CPU, and an operating system (Linux operating system) can be run in the first processor 111. The first processor 111 can realize functions such as generating and sending data traffic, which is equivalent to the traffic generation module in the above-mentioned verification system, and can be used to generate and transmit time data, and can also realize traffic capture and storage, which is equivalent to the above-mentioned traffic analysis module, capturing and saving time data; the Ethernet controller 112 is also called an Ethernet adapter, specifically a network card, and the Ethernet controller 112 supports time-sensitive networks, that is, it has time-sensitive network characteristics. The Ethernet controller 112 also includes an Ethernet interface 113, which serves as an interface for time-sensitive network networking and is used for data transmission.

[0063] The switching module 120 includes a second processor 121 and a plurality of Ethernet interfaces 122 to 126 . The integrated module 110 and the switching module 120 are connected via the Ethernet interface 113 and the Ethernet interface 122 .

[0064] Optionally, the second processor is used to configure the switching module, and is also used to generate, receive, save and send data.

[0065] It can be understood that the switching module 120 includes a second processor 121 and multiple Ethernet interfaces 122 to 126. The second processor 121 can have the same functions as the first processor 111, and can realize functions such as generating and sending data traffic, and can also realize functions such as capturing and saving traffic; multiple Ethernet interfaces 122 to 126 have the properties of time-sensitive networks, and are used to carry and forward data packets in data transmission, and according to the configuration rules of the second processor 121, schedule, preempt, copy, filter and other operations on the data packets. The specific configuration rules can be determined according to the verification requirements in the current scenario, and the function of each Ethernet interface can be further determined according to the configuration rules, for example, as a transmission interface or a sending interface.

[0066] For example, see Figure 1, the switching module 120 includes 5 Ethernet interfaces. According to the configuration rules of the second processor 121, the Ethernet interface 122 can be used to receive data transmitted by the integrated module 110, that is, the integrated module 110 transmits data to the Ethernet interface 122 through the Ethernet interface 113, completing the data transmission between the integrated module 110 and the switching module 120; the Ethernet interface 123 and the Ethernet interface 124 can also be used as data receiving interfaces (slave clock interfaces) to receive data transmitted by other verification devices, and the Ethernet interface 125 and the Ethernet interface 126 can be used as sending interfaces (master clock interfaces) to transmit the time data generated by the second processor 121 to other verification devices; wherein, the number of Ethernet interfaces included in the switching module 120 can be determined according to the address (IP) of the time-sensitive network switch (switching module 120) actually used.

[0067] A time-sensitive network verification device provided by the embodiment of the present disclosure integrates an integration module and a switching module into one verification device. The mode of the verification device can be configured to achieve different functions according to the scenario requirements of the time-sensitive network verification, thereby reducing the operation steps for selecting the device, reducing the loss of manpower and material resources, and further accelerating the speed of verifying the time-sensitive network and reducing the verification time.

[0068] Figure 2 The flowchart of a time-sensitive network verification method provided by an embodiment of the present disclosure is as follows. Based on the above embodiment, the time-sensitive network verification method is described based on the verification device 100, including: Figure 2 The following steps S210 to S230 are shown:

[0069] S210: Receive a control instruction, where the control instruction includes configuration information of the verification device.

[0070] It is understandable that the verification device receives control instructions, which include configuration information of the verification device, wherein the control instructions may be issued by a terminal connected to the verification device, and the terminal sends the generated control instructions to the verification device. The control instructions may be generated by the terminal according to the target requirements of the time-sensitive network to be verified.

[0071] Understandably, the terminal obtains the target requirements of the time-sensitive network that has been built and is to be verified. The target requirements may include the protocol of the time-sensitive network application and the number of verification devices required for verification, etc. Different target requirements can be obtained according to different scenarios. Subsequently, a control instruction is generated according to the obtained target requirements, wherein the control instruction includes configuration information of the verification device, that is, information for configuring the integrated module and the switching module in the verification device. The configuration information may specifically include whether the integrated module and the switching module are in normal working state, whether they can participate in the networking of the time-sensitive network for data transmission, and the functions to be implemented by each Ethernet interface, etc.

[0072] S220: Determine a verification mode of the verification device according to configuration information of the verification device.

[0073] It is understandable that, based on the above S210, the verification device is configured according to the configuration information of the verification device in the control instruction, and then the verification mode of the verification device is determined, and the verification device can implement different functions in different modes. For example, a mode of the verification device can be configured to implement time synchronization and data scheduling, and the verification device in this mode is equivalent to the above-mentioned end node device; or another mode of the verification device can be configured to implement time synchronization, data scheduling and data forwarding, etc., and the verification device in this mode is equivalent to the above-mentioned bridge node device.

[0074] S230: In the verification mode, verify the time-sensitive network.

[0075] It can be understood that on the basis of the above S220, using the configured verification device, in each mode of the verification device, the time-sensitive network is verified in accordance with the devices based on different functions in the above-mentioned prior art, and various functions defined in the time-sensitive network are verified. That is, in a determined mode of the verification device, functions such as time synchronization and data scheduling are realized through the time-sensitive network, that is, different modes are configured for the same verification device to assume the functions of the device required in the time-sensitive network verification.

[0076] A time-sensitive network verification method provided by the embodiment of the present disclosure is applied to the above-mentioned verification device. The verification device receives a control instruction and determines a verification mode through the control instruction. In the verification mode, the time-sensitive network is verified. The verification of a time-sensitive network can be realized based on a verification device. By configuring the same verification device to assume different functions in the time-sensitive network verification, it can be applied to a variety of application scenarios, has strong universality, and does not require relevant personnel to conduct research and selection of equipment, saving a lot of manpower and material resources, and is easy to operate, further improving the verification speed.

[0077] Based on the above embodiment, optionally, the verification mode of the verification device is determined according to the configuration information of the verification device, specifically including: Figure 3 The following steps S310 to S330 are shown:

[0078] S310: If the first processor configures the integrated module according to the configuration information, and the second processor configures the switching module according to the configuration information, it is determined that the verification mode of the verification device is the sending mode.

[0079] It can be understood that the first processor in the integrated module in the verification device is used to configure the integrated module, and the second processor in the switching module in the verification device is used to configure the switching module. The configured integrated module and the configured switching module jointly determine the verification mode of the entire verification device.

[0080] It is understandable that the first processor configures the first integrated module according to the configuration information, and the second processor configures the switching module according to the configuration information. After the configuration is completed, the verification mode of the verification device is determined to be the sending mode; that is, the integrated module is configured to be in a working state, and time data can be generated and transmitted to the switching module; at the same time, the switching module is also configured to be in a working state, and time synchronization and time data can be sent to other verification devices (verification devices whose verification mode is the forwarding mode). The above configuration rules put the verification device in the sending mode. Among them, the sending mode can realize the functions of the traffic generation module, and can also perform functions such as time synchronization, data scheduling and data forwarding, that is, it undertakes the work of both the end node and the bridge node.

[0081] S320: If only the second processor configures the switching module according to the configuration information, determine that the verification mode of the verification device is a forwarding mode.

[0082] It is understandable that the first processor in the integrated module in the verification device does not configure the integrated module, that is, the second integrated module is in a non-working state. It can also be understood that the configuration information of the control instruction does not include information for configuring the integrated module; at the same time, the second processor configures the switching module according to the configuration information, that is, the second switching module is configured to a working state, which can realize the functions of time synchronization and data forwarding; according to the above configuration rules, the verification mode of the verification device is determined to be a forwarding mode, and the verification device in the forwarding mode can realize functions such as data reception and data forwarding, that is, it undertakes the work of a bridge node.

[0083] S330: If the first processor configures the integrated module according to the configuration information, and the switching module is controlled by the configured integrated module, it is determined that the verification mode of the verification device is a receiving mode.

[0084] It can be understood that the first processor in the integrated module in the verification device configures the integrated module and configures the integrated module to a working state. Then the configured integrated module configures the switching module, that is, the integrated module controls the switching module to transmit data. The switching module can be regarded as an internal component of the integrated module. The above configuration rules put the verification device in a receiving mode. The verification device in the receiving mode can be called a third verification device; the receiving mode mainly refers to receiving time data and performing time synchronization according to the received time data, that is, undertaking the work of the end node.

[0085] A time-sensitive network verification method provided by the embodiment of the present disclosure can determine the verification mode of the verification device through control instructions, and complete the verification of the time-sensitive network in the mode corresponding to each verification device. The verification speed is relatively fast, and the structure of each verification device is the same. It only needs to determine the mode of each verification device according to the control instruction. Different modes realize different functions. For time-sensitive network verification in various scenarios, there is no need to conduct equipment research and selection, which can reduce the waste of human and material resources and has strong universality.

[0086] Based on the above embodiments, Figure 4 This is a schematic diagram of the structure of a time-sensitive network authentication system provided by an embodiment of the present disclosure. The authentication system 400 may include multiple authentication devices 100 described above, and data is transmitted between the multiple authentication devices via an Ethernet interface.

[0087] Multiple verification devices are configured into different verification modes through the above-mentioned time-sensitive network verification method, wherein the first verification device among the multiple verification devices is configured into the sending mode, the second verification device among the multiple verification devices is configured into the forwarding mode, and the third verification device among the multiple verification devices is configured into the receiving mode.

[0088] It is understandable that the modes of the first verification device, the second verification device, and the third verification device can be configured into different modes according to application requirements. For example, the first verification device can be configured into a forwarding mode, the second verification device can be configured into a receiving mode, and the third verification device can be configured into a sending mode through the configuration information in the control instruction. Among them, the number of verification devices included in the time-sensitive network verification in the verification system is at least 3, and the 3 verification devices need to be configured into a sending mode, a forwarding mode, and a receiving mode, respectively. After meeting the requirements of the verification system defined above, the specific mode and quantity of each verification device configuration can be determined according to user requirements.

[0089] Understandable, Figure 4 The verification system 400 can determine the number of verification devices 100 required to be used according to the requirements of time-sensitive network verification in different scenarios.

[0090] For example, see Figure 4 , the verification system 400 for verifying the time-sensitive network includes three verification devices. In order to facilitate the distinction of the modes configured by the verification devices, the first verification device, the second verification device and the third verification device are used for illustration, which are the first verification device 410, the second verification device 420 and the third verification device 430 respectively, and each of them represents a verification mode, wherein the three verification devices have the same structure as the above-mentioned verification device 100, and the first verification device 410, the second verification device 420 and the third verification device 430 are respectively configured into different modes through the above-mentioned time-sensitive network verification method for verifying the time-sensitive network, wherein the first verification device 410 in the verification system 400 is configured into a sending mode, the second verification device 420 is configured into a forwarding mode, and the third verification device 430 is configured into a receiving mode.

[0091] Understandable, Figure 4 The first verification device 410 (a verification device whose verification mode is a sending mode) includes a first integrated module 411 and a first switching module 414. The first verification device 410 is configured as a sending mode through the above-mentioned time-sensitive network verification method, wherein the first integrated module 411 is in a working state, and the working state refers to an application participating in a time-sensitive network, that is, data can be transmitted in a time-sensitive network. The internal transmission of the first processor 412 specifically includes: the first processor 412 generates time data and transmits the time data to the Ethernet controller 413, and then the Ethernet controller 413 transmits the time data to the first switching module 414, and then the first switching module 414 generates time data and transmits it to the second verification device 420, wherein the second verification device 420 is equivalent to a verification device whose verification mode is a forwarding mode.

[0092] Understandable, Figure 4 The second verification device 420 in the embodiment includes a second switching module 421. According to the configuration rule configured as the forwarding mode, the second integrated module in the second verification device 420 is not used and is in a non-working state. Figure 4 The internal transmission of the second verification device 420 specifically includes: the second verification device 420 receives the time data sent by the first verification device 410, performs time synchronization according to the time data, the second processor 422 generates the time data, and sends the generated time data to the third verification device 430.

[0093] Understandable, Figure 4The third verification device 430 (the verification mode is the receiving mode) includes a third integrated module 431 and a third switching module 434. The internal transmission of the third verification device 430 specifically includes: the third integrated module 431 controls the third switching module 434 to receive the time data sent by the second verification device 420, and performs time synchronization according to the time data. The dotted line in the figure indicates that the first processor 432 sends configuration information to the second processor 435, and the configuration information can be transmitted by the Ethernet interface.

[0094] A time-sensitive network verification system provided by an embodiment of the present disclosure includes a plurality of the above-mentioned verification devices 100. By configuring each verification device, each verification device has different functions. Under the premise of meeting the verification requirements, the verification of the time-sensitive network can be achieved quickly and accurately through data transmission between the verification devices, and there is no need to select the device. The operation is simple and easy to implement.

[0095] Based on the above embodiments, Figure 5 A time-sensitive network verification method provided in an embodiment of the present disclosure is applied to the verification system 400, specifically comprising: Figure 5 The following steps S510 to S530 are shown:

[0096] S510: The first verification device sends the generated first time data to the second verification device.

[0097] Optionally, the first verification device sends the generated first time data to the second verification device, specifically including: the first integration module sends the generated first time data to the first switching module; the first switching module performs time synchronization according to the first time data, and sends the updated first time data to the second verification device.

[0098] It can be understood that the first integrated module in the first verification device (the verification device whose verification mode is the sending mode) generates the first time data. Specifically, the first processor in the first integrated module generates the first time data, and transmits the first time data to the first switching module through the Ethernet interface of the Ethernet controller; the first switching module receives the first time data through the Ethernet interface, and performs time synchronization according to the first time data. After completing the time synchronization, it generates updated first time data, and transmits the updated first time data to the second verification device (the verification device whose verification mode is the forwarding mode) through the Ethernet interface.

[0099] For example, see Figure 6, the verification mode of the first verification device 610 is the sending mode. In the sending mode, the first processor 513 in the first integrated module 611 generates the first time data, and transmits the first time data to the Ethernet interface 616 in the switching module 612 through the Ethernet interface 615 in the Ethernet controller 614; the Ethernet interface 616 in the switching module 612 receives the first time data, and performs time synchronization according to the first time data. After the time synchronization is completed, the second processor 617 generates the updated first time data, and transmits the updated first time data to the Ethernet interface 623 in the second sub-verification device 620 through the Ethernet interface 618. Among them, the remaining Ethernet interfaces in the first verification device 610, the second verification device 620 and the third verification device 630 are not performing data transmission for the time being.

[0100] S520: The second verification device performs time synchronization according to the first time data, and sends the generated second time data to the third verification device.

[0101] Optionally, the second verification device performs time synchronization and sends the generated second time data to the third verification device, specifically including: the second exchange module performs time synchronization according to the updated first time data, and sends the generated second time data to the third verification device.

[0102] It can be understood that based on the above S510, after determining that the second verification device is in forwarding mode, the second switching module in the second verification device performs time synchronization according to the received updated first time data. After completing the time synchronization, the second switching module generates second time data and sends the second time data to the third verification device (the verification device whose verification mode is receiving mode) through the Ethernet interface.

[0103] For example, see Figure 6 The second verification device 620 is in forwarding mode. In this forwarding mode, the second switching module 621 receives the updated first time data transmitted by the Ethernet interface 618 in the first verification device 610 through the Ethernet interface 623, and performs time synchronization according to the updated first time data. After the second switching module 621 completes the time synchronization, the second processor 622 generates the second time data and sends the second time data to the third verification device 630 (the verification device in the receiving mode) through the Ethernet interface 624.

[0104] S530: The third verification device performs time synchronization according to the second time data.

[0105] Optionally, the third verification device performs time synchronization according to the second time data, specifically including: the third integration module controls the third switching module to perform time synchronization according to the second time data.

[0106] It can be understood that, based on the above S520, in the forwarding mode of the third verification device, the third integrated module in the third verification device controls the Ethernet interface in the third switching module to receive the second time data transmitted by the second verification device, and the third integrated module and the third switching module perform time synchronization according to the second time data.

[0107] For example, see Figure 6 The third integrated module 631 in the third verification device 630 controls the Ethernet interface 638 in the third switching module 635 to receive the second time data transmitted by the Ethernet interface 624 in the second verification device 620. The third integrated module 631 and the third switching module 635 perform time synchronization according to the second time data. The third integrated module 631 transmits configuration information to the third switching module 635 through the Ethernet interface 634 in the Ethernet controller 633. The configuration information is used to control the third switching module 635 to perform time synchronization and data reception. The Ethernet interface 636 in the third switching module 635 receives the configuration information transmitted by the Ethernet interface 634. That is, the Ethernet interface 636 and the Ethernet interface 634 are internal interfaces and do not have the properties of time-sensitive Ethernet. They are only used for internal data communication. The Ethernet interface included in the third switching module 635 has the properties of time-sensitive Ethernet and can be used in the networking of time-sensitive networks.

After the time synchronization is completed, the second time data is generated and sent to a third verification device, and the third verification device performs time synchronization according to the second time data to complete the verification of the time-sensitive network. By configuring different modes for each verification device, the verification device assumes different functions, and the verification of the time-sensitive network is realized in the mode corresponding to each verification device. It has strong flexibility and simple operation, can be applied in a variety of scenarios, has strong universality, and can realize the rapid verification of the time-sensitive network while ensuring the orderly transmission of time data.
