[0044] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0045] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0046] The current manual testing method of QinQ functions may produce complex behaviors under different network devices and different configurations, and it is easy to miss potential defects, resulting in a lack of representativeness and credibility of the test results. At the same time, manual testing cannot accurately quantify and evaluate the test process.

[0047] Therefore, in order to overcome the above-mentioned defects, the present application provides a solution, which realizes multi-threaded concurrent processing through thread pool management, and performs testing based on the address resolution protocol package, which can accurately evaluate the performance and stability of the QinQ function and ensure the accuracy and reliability of the test.

[0048] It should be noted that the execution subject of each embodiment of the present application can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a QinQ function test device, etc. The following embodiments are described below using the QinQ function test device as an example.

[0049] Based on this, the present application embodiment provides a QinQ function test method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the QinQ function testing method of the present application.

[0050] In this embodiment, the QinQ function testing method includes steps S10 to S30:

[0051] Step S10, creating a thread pool according to the test requirements and thread pool parameter configuration, applying for a first thread from the thread pool, capturing the address resolution protocol packet of a preset source physical address through the first thread, and returning the capture result within a preset time.

[0052] It should be noted that the QinQ function of the switch is a technology that expands the virtual local area network (VLAN) space by embedding another layer of 802.1Q tag on the basis of the original 802.1Q tag message to achieve two layers of virtual LAN tag encapsulation. Each data packet carries two virtual LAN identifiers, including the outer virtual LAN tag and the inner virtual LAN tag, so as to expand the available number of virtual LANs.

[0053] It is understandable that testing the QinQ function can ensure that the switch can correctly identify, process and forward data packets with double labels, which is of great significance for ensuring the correctness of network functions, performance, security, scalability, business adaptability, as well as troubleshooting and performance optimization.

[0054] In addition, it should be noted that the thread pool is a concurrent programming technology used to manage and reuse thread resources. Threads in the thread pool can be reused, reducing the overhead of creating and destroying threads. Thread pool parameter configuration refers to the various parameters that need to be set when creating a thread pool, such as the number of threads, thread priority, thread waiting time, etc. The preset source physical address refers to the pre-set physical address of the network device that needs to capture data packets. The address resolution protocol packet refers to a protocol data packet used for address resolution, which is usually used to resolve the Internet Protocol address of the network layer into the physical address of the link layer.

[0055] It should be understood that according to the test requirements and thread pool parameter configuration, a thread pool is created, and a thread is requested from the thread pool to capture the address resolution protocol packet at the preset source physical address, and then the capture result is returned within a preset time.

[0056] It can be understood that by configuring different thread pool parameters and test requirements, the concurrency and execution strategy of the test task can be flexibly adjusted, and by capturing the address resolution protocol packets on the preset source physical address, the communication behavior of the network device can be accurately located and analyzed.

[0057] It should be understood that in order to ensure the timeliness and accuracy of the test results, a preset time is set and the capture results are returned within the preset time.

[0058] Exemplarily, if an ARP packet is captured within the specified 10 seconds or if it is not captured after 10 seconds, the process will stop and return the capture result.

[0059] Step S20, after receiving the capture result, applying for a second thread from the thread pool, constructing a broadcast packet of the address resolution protocol packet through the second thread, and setting an inner virtual LAN tag of the broadcast packet.

[0060] It should be noted that a broadcast packet is a network data packet whose destination address is set to the broadcast address so that all devices in the same network can receive the data packet.

[0061] It is understandable that after receiving the capture result, a new thread (second thread) is requested from the thread pool, a broadcast packet of an address resolution protocol packet is constructed through the thread, and an inner virtual LAN label is set for it.

[0062] It should be noted that when constructing a broadcast packet of an address resolution protocol packet, an inner virtual LAN label can be specified. The outer virtual LAN label is usually added by a network device (such as a switch or router) when the data packet passes through it to meet the requirements of the QinQ protocol.

[0063] Step S30: sending the broadcast packet through the second thread, and testing the QinQ function of the switch based on the inner virtual LAN label set in the broadcast packet.

[0064] It can be understood that the QinQ function of the switch is tested by sending a broadcast packet with an inner virtual LAN label through the second thread.

[0065] For ease of understanding, the following references Figure 2 This invention is provided for illustration, but is not intended to limit the present application. Figure 2 This is a schematic diagram of the QinQ function test process for this application. The specific steps of the QinQ function test are as follows:

[0066] The network cards A and B of the automated computer are connected to the switch respectively, and the QinQ function of the switch is tested using the paramiko module, scapy module, re module, openpyxl module, logging module, and threading module in the Python library.

[0067] 1. Log in to the switch and configure QinQ

[0068] Use the paramiko module to automatically log in to the switch through the Secure Shell (SSH) protocol. Write an automated configuration script to send commands to enable the QinQ function and set it according to the parameterized configuration. Configure the interface mode of the network card A to be Trunk, the port attribute pvid to 1, and the virtual LAN tag tag to 5. Similarly, configure the interface mode of the network card B to be Trunk, pvid to 5, and tag to 1. Use the recv function to return the execution result of the send function, and synchronously use the logging module to record the execution result to the console and log file.

[0069] 2. Generate and send data packets

[0070] Use the threading module to open the thread pool, apply for the first thread from the thread pool, use the scapy module on the interface of network card B to capture the address resolution protocol packet with the source physical address sent by network card A through the first thread, and then continue to apply for the second thread. Network card A joins the second thread to construct a broadcast packet of the address resolution protocol packet, and adds a layer of VLAN5 tag with type 88a8. First, start the first thread to capture the broadcast packet. If the broadcast packet is captured within the specified 10 seconds or if it is not captured after 10 seconds, it will stop and return the result, and then start the second thread to send the broadcast packet.

[0071] Expected result: NIC B successfully captures the broadcast packet and prints all the information carried by the packet. The virtual LAN field is filtered by the re module. It must be satisfied that there are two virtual LAN tags in the packet information, the outer one is VLAN1 (the tag added by QinQ itself), and the inner one is VLAN5.

[0072] 3. Verify test results

[0073] If all the above expectations are met, the test passes, and the openyxl module is used to write all expected results into a spreadsheet for storage. There are three types of check items in the expected results of step 2. If any one of them is not met, the specific check item that failed will be written into the spreadsheet to facilitate the subsequent location of specific problems. If all check items pass, they will be directly written as passed.

[0074] This embodiment creates a thread pool according to the test requirements and thread pool parameter configuration, and uses the first thread of the thread pool to capture the address resolution protocol packet of a specific source physical address. Once the capture result is returned, the second thread is immediately applied to construct and send a broadcast packet with an inner virtual LAN label, so as to test the QinQ function of the switch, which can comprehensively and accurately evaluate the performance and stability of the QinQ function, ensuring the accuracy and reliability of the test.

[0075] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , the step S30 may include steps S301-S302:

[0076] Step S301: sending the broadcast packet through the second thread, and obtaining the virtual local area network field of the broadcast packet based on the data parsing module after the first thread captures the broadcast packet.

[0077] It should be noted that the data parsing module may be a component for parsing the content of a data packet, which can read various fields in the data packet and extract, convert or process the data as required.

[0078] It is understandable that the broadcast packet is sent through the second thread, and after the first thread captures the broadcast packet, the data parsing module is used to parse the data packet content, thereby obtaining the virtual local area network field in the broadcast packet. The virtual local area network field may include a virtual local area network tag, a virtual local area network name, a type or other extended fields.

[0079] Step S302, matching the virtual LAN field with the inner virtual LAN tag and the preset virtual LAN tag information to obtain a QinQ function test result of the switch.

[0080] It should be noted that the preset virtual local area network tag information may include outer virtual local area network tag information, type, priority, and matching rule or logic.

[0081] It is understandable that QinQ allows two virtual LAN labels to be carried in one Ethernet frame: an inner label and an outer label. In order to ensure the accuracy and comprehensiveness of the test results, first check whether the virtual LAN field of the broadcast packet contains the inner virtual LAN label and the outer virtual LAN label, and then match the two labels based on the inner virtual LAN label and the preset virtual LAN label information set in the above steps to obtain the test results.

[0082] Therefore, the step S302 may include: when the virtual LAN field contains two virtual LAN tags, matching the virtual LAN field with the inner virtual LAN tag; matching the virtual LAN field with the outer virtual LAN tag in the preset virtual LAN tag information to obtain the QinQ function test result of the switch.

[0083] Furthermore, in order to improve the comprehensiveness of the QinQ function test, after step S302, the following steps are further included:

[0084] If the QinQ function test result is that the test fails, the mismatch item is recorded;

[0085] According to the mismatched items, the switch and the test-related items are adjusted to obtain adjusted test-related items;

[0086] The QinQ function is tested according to the thread pool and the adjusted test related items.

[0087] It is understandable that in order to identify the problem and make targeted adjustments later, when performing QinQ functional testing, if the test results show that the functional test fails (that is, the inner and outer virtual LAN labels of the data packet do not match the preset information, or there are other unexpected situations), these mismatches need to be recorded. These mismatches may include incorrect labels or missing label information, incorrect priority settings, etc.

[0088] It should be understood that after recording the mismatches, adjustments need to be made based on this information, which may involve modifying the switch configuration (such as virtual LAN settings, priority configuration, etc.), or adjusting the test tools, test environment, or test parameters.

[0089] In this embodiment, a broadcast packet is sent through the second thread. After the first thread captures the broadcast packet, the virtual LAN field of the broadcast packet is extracted using the data parsing module. When the virtual LAN field contains two virtual LAN tags, the two tags are matched with the inner virtual LAN tag and the preset virtual LAN tag information respectively to verify whether the QinQ function of the switch is normal. If the test result fails, that is, there are mismatches, these mismatches are recorded, and the switch and test-related items are adjusted based on this information, and then the test is performed again. Through multi-threaded concurrent execution, the test speed can be accelerated, the test cycle can be shortened, the accuracy of the test results is ensured, and it is helpful to quickly locate and solve problems.

[0090] Based on the first embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 4 After step S10, steps S11 to S12 may also be included:

[0091] Step S11, capturing network data packets through the first thread to verify the network environment and obtain a network verification result.

[0092] It should be noted that network data packets are large blocks of data divided into small blocks, each of which is encapsulated in an independent data packet and carries some necessary control information. These data packets are transmitted in the network through routers, switches and other network devices.

[0093] It should be understood that the network environment is the entire network topology and configuration status of the switch and its connected devices, which can include: 1) Physical connection, including the physical link connection status between the switch and other network devices (such as routers, servers, terminal devices, etc.), such as whether the optical fiber, network cable, etc. are connected normally. 2) Network topology: refers to the connection relationship and hierarchy between various devices in the network, including the location of the switch, the connection path with other devices, etc. 3) Network performance: network bandwidth, delay, packet loss rate and other performance indicators.

[0094] It is understandable that in order to ensure that the QinQ function test can be performed in a stable and reliable network environment, the network environment can be verified by capturing network data packets to check network connectivity, security, etc.

[0095] Step S12: adjusting the network environment according to the network verification result.

[0096] It is understandable that adjustments to the network environment can be made by optimizing the physical layout, adjusting network performance (bandwidth optimization, delay and packet loss rate control, load balancing, etc.), enhancing security, etc.

[0097] This embodiment verifies the network environment, so that potential problems can be discovered and solved in advance, ensuring that the QinQ function test can be performed in a healthy, stable and expected network environment, thereby improving the accuracy and effectiveness of the test.

[0098] In the third embodiment, before step S10, the following steps may also be included:

[0099] Set the switch's interface mode and virtual LAN information according to the preset configuration requirements, and obtain the configuration execution result through the data receiving function.

[0100] Based on the log module, record the configuration execution result;

[0101] Configure the QinQ function of the switch according to the preset configuration information;

[0102] Generate an address resolution protocol packet through the thread pool based on the configuration result and the test requirement;

[0103] The address resolution protocol packet is stored in a preset storage space, and a preset source physical address corresponding to the preset storage space is generated.

[0104] It is understandable that setting according to the preset configuration requirements is the initial configuration stage before the QinQ function test of the switch. The preset configuration requirements can be set based on factors such as network architecture, security policy, performance requirements, etc., and the interface mode (such as Access mode, Trunk mode, etc.) and virtual LAN information of the switch can be set according to the preset configuration requirements. After the configuration is completed, the configuration execution result is obtained through the data receiving function to confirm whether the configuration is successfully applied.

[0105] It should be noted that the virtual local area network information may include a virtual local area network unique identifier, a virtual local area network name, virtual local area network members, and the like.

[0106] In addition, it should be noted that the log module is a component used to record system events, errors, warnings, etc. After configuring the switch, the configuration execution results (success or failure, and possible error codes or descriptions) are recorded in the log.

[0107] It is understandable that according to the QinQ function configuration result of the switch and the test requirements (such as the specific scenario of testing the QinQ function, data packet size, transmission rate, etc.), the address resolution protocol packet is generated through the thread pool. In addition, the transmission control protocol data packet, the user datagram protocol data packet or other specific application data packets can also be generated.

[0108] This embodiment sets the interface mode and virtual LAN information of the switch according to the preset configuration requirements, obtains the results of the configuration execution through the data receiving function, uses the log module to record the results of these configuration executions, configures the QinQ function according to the preset configuration information, and generates an address resolution protocol packet through the thread pool based on the configuration results and test requirements, thereby achieving precise control and testing of the switch configuration, avoiding human configuration errors, and improving test efficiency.

[0109] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the QinQ function testing method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0110] This application also provides a QinQ function test device, please refer to Figure 5 , the QinQ function test adjustment device comprises:

[0111] The data packet capture module 10 is used to create a thread pool according to the test requirements and the thread pool parameter configuration, apply for a first thread from the thread pool, capture the address resolution protocol packet of the preset source physical address through the first thread, and return the capture result within a preset time;

[0112] The data packet sending module 20 is used for applying for a second thread from the thread pool after receiving the capture result, constructing a broadcast packet of the address resolution protocol packet through the second thread, and setting an inner virtual local area network label of the broadcast packet;

[0113] The function testing module 30 is used to send the broadcast packet through the second thread, and test the QinQ function of the switch based on the inner virtual LAN label set in the broadcast packet.
