[0002] Industrial-grade virtualized real-time operating systems can host multiple real-time operating systems. These different real-time operating systems are hosted in different virtual machines. Different real-time operating systems can communicate through virtual networks. How to determine the real-time performance of communication between different real-time operating systems has become an important research topic. At present, there is a lack of methods to determine the real-time performance of communication between different real-time operating systems.

[0003] However, due to the lack of methods to determine the real-time nature of communication between different real-time operating systems, the following technical problems often occur:

[0004] Industrial networks have high requirements for the real-time performance of operating systems. If real-time testing cannot be performed, it will be impossible to determine whether the real-time performance of the real-time operating system meets the needs of industrial application scenarios, which will lead to lower security of industrial application scenarios. Summary of the invention

[0005] The content of this disclosure is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this disclosure is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

Specifically, the reason for the low security of industrial application scenarios is that the industrial network has high requirements for the real-time performance of the operating system. If the real-time performance test cannot be performed, it will be impossible to determine whether the real-time performance of the real-time operating system meets the requirements of the industrial application scenario, thereby resulting in low security of the industrial application scenario.

Secondly, according to the preset number of packet transmissions, the above-mentioned test module sends a data packet to the above-mentioned configuration virtual machine, and the above-mentioned data recording module records the transmission data. Thus, a data packet can be sent to the configuration virtual machine, and the communication information when the data packet is sent can be recorded. Then, according to at least one transmission data recorded by the above-mentioned data recording module, a transmission data set is determined. Thus, the communication jitter and communication delay between the test virtual machine and the configuration virtual machine can be determined. Finally, according to the above-mentioned transmission data set, communication test information is generated. Thus, the communication test information between the test virtual machine and the configuration test virtual machine is determined, and whether the real-time performance of the real-time operating system meets the requirements of the industrial application scenario is determined, thereby improving the security of the industrial application scenario.

[0027] It should be understood that Figure 1 The number of computing devices in the embodiment is only illustrative. Any number of computing devices may be provided according to implementation requirements.

[0028] Figure 2 The process 200 of some embodiments of the inter-virtual machine communication test method according to the present disclosure is shown. The inter-virtual machine communication test method includes the following steps:

[0029] Step 201: Establish a communication connection with a configuration virtual machine through a communication module.

[0030] In some embodiments, the execution subject (eg, Figure 1 The test virtual machine 101 shown can establish a communication connection with the test virtual machine through the communication module. In practice, the execution subject can establish a communication connection with the test virtual machine through the transceiver function driven by the virtual network (VNet, Virtual Network) included in the communication module. Among them, the execution subject can be a test virtual machine. The test virtual machine can be a virtual machine that needs to perform a communication test. The test virtual machine can be a virtual machine that cooperates with the test virtual machine to perform a communication test. Both the test virtual machine and the test virtual machine have a network tester. The network tester can include a communication module, a test module and a data recording module. The communication module can be a module for communication between virtual machines. The communication module includes a communication receiving function and a communication sending function. The communication receiving function is used to receive a data packet sent by an associated terminal or virtual machine. The communication sending function is used to send a data packet to an associated terminal or virtual machine. The test module can be a module for testing the communication jitter between different real-time operating systems carried by an industrial-grade virtualized real-time operating system. The data recording module can be a module for counting the communication jitter test results between different real-time operating systems. The test virtual machine and the configuration virtual machine may be virtual machines in the industrial-grade virtualized real-time operating system. For example, the industrial-grade virtualized real-time operating system may be an Intewell system.

[0031] Optionally, before step 202, a test mutex is created according to preset configuration information.

[0032] In some embodiments, the execution subject may create a test mutex according to preset configuration information, wherein the preset configuration information may be pre-set configuration information of the test mutex.

[0033] Optionally, before step 202, the test mutex is added to the communication module, so that the test mutex is adapted to the communication receiving function and the communication sending function included in the communication module.

[0034] In some embodiments, the execution entity may add the test mutex to the communication module so that the test mutex adapts to the communication receiving function and the communication sending function included in the communication module.

[0035] Step 202: according to a preset number of packet transmission times, a data packet is transmitted to the configured virtual machine through the test module, and the transmitted data is recorded through the data recording module.

[0036] In some embodiments, the execution subject may send a data packet to the test virtual machine through the test module according to a preset number of packet sending times, and record the sent data through the data recording module. The preset number of packet sending times may be a preset number of times that a data packet needs to be sent to the test virtual machine. For example, the preset number of packet sending times may be 10.

[0037] In practice, the execution subject may send a data packet to the configuration virtual machine through the following steps:

[0038] The first step is to perform the following processing steps based on the above-mentioned preset number of packet transmissions and the pre-acquired data packets:

[0039] The first processing step is to send the data packet to the test virtual machine through the test module and generate a first timestamp. The first timestamp may be a timestamp used to represent the time point when the test virtual machine sends the data packet. The timestamp may be a complete and verifiable data that indicates that a piece of data existed before a specific time, usually a character sequence.

[0040] The second processing step is to update the initial value of the number of packet transmissions and generate a second timestamp in response to the test virtual machine receiving the data packet. In practice, in response to receiving the data packet sent by the test virtual machine, the test virtual machine can control the included test module to block packet reception and return the data packet to the test virtual machine. The initial value of the number of packet transmissions is initially 0. The second timestamp can represent the time point when the data packet is received. As an example, in response to the initial value of the number of packet transmissions being 0 and the test virtual machine receiving the data packet, the initial value of the number of packet transmissions can be updated to 1.

[0041] The third processing step is to generate transmission data according to the first timestamp and the second timestamp, and to send the transmission data to the data recording module. In practice, the duration between the time point represented by the second timestamp and the time point represented by the first timestamp can be determined as the transmission data. Here, the state of the data recording module included in the configuration virtual machine is disabled.

[0042] The fourth processing step is to execute the above processing step again in response to the initial value of the number of packet sending times being less than the preset number of packet sending times.

[0043] The second step is to send a stop receiving message to the data recording module in response to the initial value of the number of packet transmissions being equal to the preset number of packet transmissions. The stop receiving message may indicate that the data recording module stops receiving the transmission data sent by the test module. For example, the stop receiving message may be "stop receiving transmission data".

[0044] Step 203: Determine a sending data set according to at least one sending data recorded by the data recording module.

[0045] In some embodiments, the execution subject may determine the transmission data set according to at least one transmission data recorded by the data recording module. In practice, the execution subject may determine each received transmission data as the transmission data set in response to receiving the stop receiving information.

[0046] Step 204: Generate communication test information according to the sent data set.

[0047] In some embodiments, the execution entity may generate communication test information based on the sent data set.

[0048] In practice, the execution subject may generate communication test information according to the sending data set through the following steps:

[0049] The first step is to sort the individual transmission data in the transmission data set to generate sorted transmission data as a transmission data sequence. In practice, the execution subject may sort the individual transmission data in the transmission data set according to the time when the data recording module receives the individual transmission data to generate sorted transmission data as a transmission data sequence.

[0050] In the second step, for each two adjacent transmission data in the transmission data sequence, a difference between the two adjacent transmission data is determined as a communication jitter value.

[0051] In the third step, the maximum value among the determined communication jitter values ​​is determined as the maximum communication jitter value, and the minimum value among the determined communication jitter values ​​is determined as the minimum communication jitter value.

[0052] In the fourth step, the maximum value of each transmission data in the above transmission data sequence is determined as the maximum communication delay value, and the minimum value of each transmission data in the above transmission data sequence is determined as the minimum communication delay value.

[0053] The fifth step is to determine the maximum communication jitter value, the minimum communication jitter value, the maximum communication delay value and the minimum communication delay value as communication test information.

[0054] Optionally, after step 102, a communication test image is generated according to the communication test information.

[0055] In some embodiments, the execution subject may generate a communication test image based on the communication test information. The communication test image may represent the relationship between the various numerical values ​​included in the communication test information. For example, the communication test image may be a bar chart. In practice, the execution subject may generate the communication test image using various methods. For example, a drawing tool may be used to generate the communication test image.

[0056] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through the inter-virtual machine communication test method of some embodiments of the present disclosure, the real-time communication between different real-time operating systems is determined, and the security of industrial application scenarios is improved. Specifically, the reason for the low security of industrial application scenarios is that the industrial network has high requirements for the real-time performance of the operating system. If the real-time performance test cannot be performed, it will be impossible to determine whether the real-time performance of the real-time operating system meets the requirements of the industrial application scenario, thereby resulting in low security of the industrial application scenario. Based on this, the inter-virtual machine communication test method of some embodiments of the present disclosure, first, establishes a communication connection with the configuration virtual machine through the above-mentioned communication module. Thus, the communication test information between the test virtual machine and the configuration virtual machine can be determined. Secondly, according to the preset number of packet transmissions, the above-mentioned test module sends a data packet to the above-mentioned configuration virtual machine, and the above-mentioned data recording module records the transmission data. Thus, a data packet can be sent to the configuration virtual machine, and the communication information when the data packet is sent can be recorded. Then, according to at least one transmission data recorded by the above-mentioned data recording module, a transmission data set is determined. Thus, the communication jitter and communication delay between the test virtual machine and the configuration virtual machine can be determined. Finally, according to the above-mentioned transmission data set, communication test information is generated. Thus, the communication test information between the test virtual machine and the configuration test virtual machine is determined, and whether the real-time performance of the real-time operating system meets the requirements of the industrial application scenario is determined, thereby improving the security of the industrial application scenario.

[0057] The technical details are further described below in conjunction with embodiments.

[0058] Example 1

[0059] The inter-virtual machine communication testing method disclosed in Example 1 may include the following steps:

[0060] The first step is to determine the Intewell system version, and run the Intewell system corresponding to the Intewell system version on a preset hardware platform. The Intewell system version may be V1.8.0_beta. The preset hardware platform may be a Loongson Pie 2 development board platform.

[0061] The second step is to create a Hypervisor project in IntewellDeveloper, configure two real-time operating systems, and configure the virtual network cards (VNET) separately.

[0062] The third step is to create two virtual machine projects in IntewellDeveloper, corresponding to the two configured real-time operating systems, and configure their respective IP addresses.

[0063] The fourth step is to compile, download, and run the RAWSOCKET communication test case in the two configured real-time operating systems to make the RAWSOCKET communication between the two real-time operating systems work.

[0064] Step 5: Design and add the RTCommTest communication real-time tester InterCom module in the real-time operating system. The InterCom module can be controlled to perform the following sub-steps:

[0065] In the first sub-step, the InterCom module is controlled to call the driver packet receiving functions ls2k1000_rx() and ls2k1000_tx() of the virtual network card driver of the Loongson Pi 2 to implement the communication receiving function InterCom_Hal_RX() and the communication sending function InterCom_Hal_TX().

[0066] The second sub-step is to control the InterCom module to lock the mutex for communication reception and transmission to ensure that resource reuse does not conflict.

[0067] Step 6: Design and add the RTCommTest_M communication real-time tester RTtest module in the real-time operating system. The RTCommTest_M communication real-time tester RTtest module can be controlled to perform the following sub-steps:

[0068] The first sub-step is to control RTtest to read the value of the macro configuration TestMode. If it is 1, RTtest_M is enabled to perform communication jitter testing.

[0069] The second sub-step is to control RTtest_M to cyclically call InterCom_Hal_TX() to send packets and record the timestamp as T0.

[0070] The third sub-step is to control RTtest_M to call InterCom_Hal_TX() to send a packet, and then immediately call InterCom_Hal_RX() to block the packet reception and record the timestamp as T1.

[0071] The fourth sub-step is to calculate the difference ΔT=T1-T0 between one transmission and reception, and pass it to the TestShow module for recording through a variable.

[0072] The fifth sub-step is to repeat the test in the loop according to the macro definition TESTCOUNT times.

[0073] Step 7: Design and add the RTCommTest_S communication real-time tester RTtest module in the real-time operating system. Among them, RTCommTest_S's RTtest mainly implements the test function, blocks the packet receiving in the loop, and sends the received packet back immediately. The specific sub-steps are as follows:

[0074] In the first sub-step, RTtest reads the value of the macro configuration TestMode. If it is 0, RTtest_S is enabled to test the communication jitter.

[0075] In the second sub-step, RTtest_S cyclically calls InterCom_Hal_RX() to block packet reception.

[0076] The third sub-step is to return the data packet after receiving the packet.

[0077] Step 8. Design and add the RTCommTest_M / S communication real-time tester TestShow module in the real-time operating system. The TestShow module is mainly run in the RTCommTest_M communication real-time tester and is disabled in the RTCommTest_S communication real-time tester. It mainly realizes reading the test results of the RTtest_M module and displaying them. In practice, the TestShow module can be controlled to execute the following sub-steps:

[0078] In the first sub-step, TestShow reads the value of the macro configuration TestMode. If it is 1, it is enabled, and if it is 0, it is disabled.

[0079] In the second sub-step, TestShow reads the test result ΔT in RTtest_M and records it. The interpolation of two ΔTs is ΔT_jitter, which is the communication jitter, and ΔT is the communication delay. Record the maximum and minimum values ​​and other communication data.

[0080] In the ninth step, you can export the communication data and use the drawing tools to visually see the distribution of real-time indicators.
