[0029] Currently, checking the network physical topology (i.e., the physical connections of network cables and fiber optic cables) of a system in a computer room to ensure its correctness and compliance with design requirements mainly relies on manual verification of the labels at both ends of the cables. Two people are needed at each end of the cable to complete this task using a cable tester. Given the large number of devices and fiber optic cables in a real computer room, which can be overwhelming, manual inspection of each cable is difficult, error-prone, and extremely inefficient. Furthermore, for certain special application scenarios, it is necessary for third-party personnel to conduct the verification, rather than relying on the actual system administrators. Therefore, there is an urgent need for an efficient, accurate, and easy-to-use verification method. To address the problems of the existing technology, which relies on manual inspection of each cable, is difficult to verify, prone to errors, and extremely inefficient, the following technical solution is proposed in this application.

[0030] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0031] Figure 1 This is a schematic flowchart of a method for verifying network physical topology provided in an embodiment of this application. Figure 1 ,like Figure 1 As shown, the method for verifying the network physical topology includes the following steps:

[0032] Step 101: For each device in the target system, obtain the device information for each device.

[0033] The target system is the system to be verified. For each device in the system to be verified, it is necessary to obtain the device information of each device. Each device in the target system includes, but is not limited to, switches, routers, firewalls, load balancers, servers, storage devices, etc. The specific devices in the target system need to be determined according to the actual situation, and this application does not make specific limitations in this regard.

[0034] In some implementations, the method for verifying network physical topology is applied to a network device. Specifically, the network device obtains device information for each device in the system to be verified in order to generate the network physical topology for subsequent verification of the system.

[0035] In some implementations... Figure 2 This is a schematic flowchart of a method for obtaining device information for each device provided in an embodiment of this application, such as... Figure 2 As shown, obtaining the device information for each device includes: sequentially designating each device as a target device and executing steps 201 to 202:

[0036] Step 201: Obtain a first photo and a second photo taken by the scanning device. The first photo is obtained by taking a picture of the panel of the target device, and the second photo is obtained by taking a picture of the identification label on the cable connected to the network port on the panel of the target device.

[0037] In some embodiments, the scanning device has a module capable of capturing images. For example, this module can be a camera module. In some embodiments, the camera module is also equipped with a module for fine-tuning the focus. For example, this module is a focus fine-tuning button. The function of the focus fine-tuning button is to zoom in and / or zoom out. For example, the focus fine-tuning button can be set to two independent buttons for adjusting the focus, or it can be set to one button to zoom in and / or zoom out, or it can be set to a rotating button for adjusting the focus. The specific settings of the focus fine-tuning button can be set according to the actual situation, and this application does not make specific limitations in this regard.

[0038] In some implementations, the target device is the device currently being verified. First, the scanning device frames the front panel and / or rear panel of the device being verified, adjusts the focus appropriately, and obtains a first photo. Then, the scanning device takes a picture of the identification label on the cable connected to the network port of the device being verified, adjusts the focus appropriately, and obtains a second photo. The scanning device then sends the first and second photos to the network device. The scanning device also includes a communication module for communication, through which it sends the first and second photos to the network device.

[0039] In some embodiments, acquiring a first photograph and a second photograph taken by a scanning device includes: receiving a first operation signal sent by the scanning device; identifying the first operation signal and generating a first operation instruction corresponding to the first operation signal; sending the first operation instruction to the scanning device, wherein the first operation instruction is used to trigger the scanning device to take a first photograph; receiving the first photograph sent by the scanning device; receiving a second operation signal sent by the scanning device; identifying the second operation signal and generating a second operation instruction corresponding to the second operation signal; sending the second operation instruction to the scanning device, wherein the second operation instruction is used to trigger the scanning device to take a second photograph; and receiving the second photograph sent by the scanning device.

[0040] In some embodiments, the scanning device includes a module for receiving a first operation signal and a second operation signal; exemplarily, this module can be a human-machine interface (HMI) module. In some embodiments, the HMI module on the scanning device receives the first operation signal, and the scanning device sends the first operation signal to a network device via a communication module. The network device identifies the first operation signal and generates a first operation command corresponding to the first operation signal. Then, the network device sends the first operation command to the scanning device, and the scanning device takes a first photograph based on the first operation command. Similarly, the HMI module on the scanning device receives a second operation signal, and the scanning device sends the second operation signal to a network device via a communication module. The network device identifies the second operation signal and generates a second operation command corresponding to the second operation signal. Then, the network device sends the second operation command to the scanning device, and the scanning device takes a second photograph based on the second operation command.

[0041] In some embodiments, the aforementioned human-computer interaction module can be a microphone and / or earphone module. The scanning device receives a first operation signal and a second operation signal through the microphone and / or earphone module. For example, the first and second operation signals are voice signals. The network device generates a corresponding operation command based on the voice signal. Specifically, the first and second operation signals are "take a picture" voice signals. The scanning device receives the "take a picture" voice signal through the microphone and / or earphone module, and then sends the "take a picture" voice signal to the network device through the communication module. After recognizing the "take a picture" voice signal, the network device generates a corresponding "take a picture" operation command. The scanning device receives the "take a picture" operation command and triggers the camera module of the scanning device to take a picture based on the "take a picture" operation command, thereby obtaining a first photo and a second photo. The scanning device then sends the first and second photos to the network device.

[0042] Step 202: Identify the first and second photos to obtain the device information of the target device, which includes the target device's attribute information and network port information.

[0043] In some implementations, the attribute information includes at least one of the following: device type, device name, device identifier, and device panel location; the network port information includes at least one of the following: port type, number of ports, and port occupancy status. For example, the aforementioned device information can be represented in tabular form, the device panel location can be a front panel or a rear panel, the port type can be an optical port or a network port, and the port occupancy status can indicate whether the port is active, etc. The specific identified device information and its representation are set according to specific circumstances, and this application does not impose specific limitations on them.

[0044] In some embodiments, after identifying the first and second photos to obtain the device information of the target device, the method further includes: sending the device information of the target device to a scanning device to display the device information of the target device on the scanning device; receiving a third operation signal sent by the scanning device, identifying the third operation signal and generating first supplementary information of the target device, and updating the device information of the target device in a database according to the first supplementary information, wherein the third operation signal is triggered by the user according to the device information of the target device; and / or sending the device information of N devices in the database to the scanning device to display the device information of N devices on the scanning device, wherein the N devices are devices in the target system other than the target device, and N is a positive integer; receiving a fourth operation signal sent by the scanning device, identifying the fourth operation signal and generating second supplementary information of the target device, and updating the device information of the target device in the database according to the second supplementary information, wherein the fourth operation signal is triggered by the user according to the device information of the N devices.

[0045] It should be noted that network devices include databases.

[0046] In some implementations, the aforementioned scanning device includes a module that can display device information, etc. For example, the module that displays device information can be a display module. Specifically, the network device sends device information to the scanning device, and the display module on the scanning device displays the device information of the target device.

[0047] In some embodiments, based on the device information displayed by the display module, a third operation signal is received through the human-machine interaction module of the scanning device, and the third operation signal is sent to the network device. The network device recognizes the third operation signal and generates first supplementary information for the target device. Based on the first supplementary information, the device information of the target device is updated in the database. The third operation signal is triggered by the user based on the device information of the target device. For example, the third operation signal is a voice signal. The network device receives and recognizes the voice signal and generates the first supplementary information. Specifically, based on the displayed device information, the scanning device receives the user's voice signal through a microphone and / or earphone module. This voice signal is used to input supplementary information about the device to be verified. The network device receives and recognizes the voice signal, generates the first supplementary information, and updates the device information of the target device in the database based on the first supplementary information. That is, the relevant information about the device to be verified is input via voice. In some embodiments, the first supplementary information includes, but is not limited to, assigning an identification (ID) number to the target device, other potentially missing or unrecognized information, etc. The specific first supplementary information is set according to the actual situation, and this application does not specifically limit it.

[0048] In some implementations, the network device can also send device information of N existing devices from the database to the scanning device, so that the device information of the N devices can be displayed on the display module of the scanning device. Here, the N devices are devices in the target system other than the target device, and N is a positive integer. The network device receives a fourth operation signal sent by the scanning device, recognizes the fourth operation signal, generates second supplementary information for the target device, and updates the device information of the target device in the database according to the second supplementary information. The fourth operation signal is triggered by the user based on the device information of the N devices. For example, the fourth operation signal can be a voice signal. The network device receives and recognizes the voice signal and generates the second supplementary information. Specifically, based on the displayed device information, the scanning device receives the user's voice signal through a microphone and / or earphone module. This voice signal is used to input supplementary information about the device to be verified. The network device recognizes the voice signal and generates the second supplementary information for the target device, and updates the device information of the target device in the database according to the second supplementary information, i.e., the relevant information of the device to be verified is input via voice. In some implementations, the second supplementary information can be determined based on the device information of the N devices displayed, including but not limited to the ID number assigned to the target device, other information that may be missing, etc. The specific second supplementary information is set according to the actual situation, and this application does not make specific limitations on it.

[0049] It should be noted that the scanning device can display the device information of the target device alone, or it can display the device information of one or more devices in the system to be verified except for the target device alone, or it can display the device information of the target device and the device information of one or more devices in the system to be verified at the same time. The specific display situation is determined according to the actual situation, and this application does not make specific limitations in this regard.

[0050] Step 102: Send the device information of each device to the database. The database has pre-entered the system identifier and location information corresponding to each device.

[0051] In some implementations, before verifying each device in the system to be verified, a unique system ID number needs to be assigned to the system in the database. All devices belonging to the system to be verified are assigned this system ID number, which serves as the unique identifier for the system. Simultaneously, the location information of the system to be verified is entered into the database. For example, the location information gradually narrows down from a broad geographical area to a specific room. For instance, the location information may include: the city where the server room is located, the street where the server room is located, the latitude and longitude of the server room, the building number of the server room, the room number of the server room, the rack row (column) number where the device of the system to be verified is located, the rack number, and the U-position within the rack. For each location information, if any one of the location elements differs, it is considered a different location. Specifically, when the location information of the devices belonging to the system to be verified is different, multiple location information entries are required. The specific location information can be set according to actual conditions, and this application does not impose specific limitations on it.

[0052] Step 103: Analyze each device based on its device information, system identifier, and location information in the database to obtain the analysis results.

[0053] In some implementations, after all devices in the system to be verified have been verified, the verification personnel automatically invoke the "network topology analysis module" in the network devices through automated means. Specific invocation methods include, but are not limited to, voice commands, real-time commands, timed commands, and command orchestration. The specific invocation method can be determined according to the actual situation, and this application does not impose specific limitations on it. The network topology analysis module automatically processes the device information, system identifier, and location information of each device in the database to obtain the analysis results.

[0054] In some implementations, each device is analyzed based on its device information, system identifier, and location information in the database to obtain analysis results, including: determining devices belonging to the same target system based on the system identifier and location information of each device in the database; and for each device belonging to the same target system, taking each device as a target device in turn, and analyzing each network port of the target device based on the device information of the target device.

[0055] In some implementations... Figure 3 This is a schematic flowchart of a method for analyzing each network port of a target device according to an embodiment of this application. Figure 3 As shown, the analysis of each network port of the target device includes: taking each network port of the target device as the target port in sequence, and executing steps 301 to 303:

[0056] Step 301: Determine if the target port is connected to a cable.

[0057] Step 302: If no cable is connected to the target port, set the target port to idle.

[0058] Step 303: With the target port connected to the cable, determine whether the opposite port of the target port is idle.

[0059] In some implementations, if the peer port is not idle, it is determined whether the physical connection between the peer port and the target port matches. If they do not match, it is determined that the target port is abnormal. If they match, it is determined that the target port is not abnormal. If the peer port is idle, a physical connection between the target port and the peer port is established.

[0060] In some implementations, based on device information, the network ports of each device are analyzed to determine whether each network port is connected to a cable and whether the port on the other end of the cable is idle, so as to determine the connection status of each network port. If the connection status of a network port is occupied, it is determined whether the network port of the other end device is occupied. Or, if the network port of the other end device is not connected to the network port of this end device, the connection status is corrected to generate a topology diagram of the network physical connection of the system to be verified.

[0061] In some implementations, the system first determines whether the target port is connected to a cable. If no cable is connected, the target port is set to "idle." If the target port is connected to a cable, it determines whether the peer port is idle. If the peer port is not idle (i.e., it is occupied), it determines whether the physical connection between the peer port and the target port matches. Specifically, it identifies which device and which port the peer port belongs to. If they do not match, the target port is considered abnormal; if they match, the target port is considered normal. If the peer port is idle, a physical connection is established between the target port and the peer port. If the target port is occupied but no peer port is currently matched, it is temporarily set to "idle."

[0062] In some implementations, after analyzing the target port, the aforementioned device information can be updated in the database based on the analysis results.

[0063] Step 104: If there is no abnormal network port information in the analysis results, output the network physical topology diagram of the target system; if there is abnormal network port information in the analysis results, output the abnormal information.

[0064] In some implementations, if no abnormal network port information is found in the analysis results, a topology diagram reflecting the physical network connections of the target system is output; if abnormal network port information is found in the analysis results, abnormal information is output. For example, abnormal information in the analysis results means that there are contradictions in the analysis results, such as: the cable label of the "local" port of some devices shows that it is occupied, but the "other end" port of the interconnected cable is actually free; or the actual label of the "local" port cable of the device is inconsistent with the actual "other end" port of the interconnected cable, etc., then an error alarm result is output. The specific abnormal information can be set according to the actual situation, and this application does not make specific limitations on it.

[0065] In some implementations, if abnormal network port information is found in the analysis results, a result report indicating the presence of abnormal information is output.

[0066] In some implementations, if abnormal information is found, the abnormal information is corrected and a topology diagram of the physical network connections of the system to be checked is generated.

[0067] In some implementations, the aforementioned anomaly information or network physical topology diagram can be displayed on the display module of the scanning device, making the results easier to confirm.

[0068] In some implementations, multiple scanning devices can be checked simultaneously in different computer rooms, and the various functional modules of the network device can also be shared remotely. For example, the various functional modules of the network device can be shared in the cloud. The aforementioned functional modules located in the cloud support collaborative mechanisms such as caching, queuing, multi-threading, and resource locking to ensure that when requests from multiple scanning devices are received, the relevant processing resources can be called in an orderly manner. The requests from multiple scanning devices include, but are not limited to, scanning data entry, data retrieval, identification, and algorithm invocation. The specific sharing method or the requests from the scanning devices can be determined according to the actual situation, and this application does not make specific limitations in this regard.

[0069] The technical solution provided in this application involves acquiring device information for each device in the target system; sending this device information to a database, which pre-stores the system identifier and location information corresponding to each device; analyzing each device based on its device information, system identifier, and location information to obtain analysis results; outputting a network physical topology diagram of the target system if no abnormal network port information is found in the analysis results; and outputting abnormal information if abnormal network port information is found in the analysis results. Thus, by analyzing the acquired device information and pre-stored information, an analysis result can be obtained, enabling efficient, accurate, reliable, and easy-to-use automatic verification of the system's network physical topology, while also providing an independent and objective verification method.

[0070] Figure 4 This is a schematic diagram of the system architecture for verifying network physical topology provided in the embodiments of this application. Figure 1 ,like Figure 4 As shown, the system includes: a network device 401, which includes an identification module 4011, a network topology analysis module 4012, and a database 4013; wherein,

[0071] The identification module 4011 is used to acquire device information for each device in the target system; and send the device information of each device to the database 4013, in which the system identifier and location information corresponding to each device are pre-entered.

[0072] The network topology analysis module 4012 is used to analyze each device based on the device information, system identifier, and location information of each device in the database 4013, and obtain the analysis results. If there is no abnormal network port information in the analysis results, the network physical topology diagram of the target system is output; if there is abnormal network port information in the analysis results, abnormal information is output.

[0073] In some implementations, each device is sequentially designated as a target device. The identification module 4011 is specifically used to acquire a first photo and a second photo taken by the scanning device. The first photo is obtained by taking a picture of the panel of the target device, and the second photo is obtained by taking a picture of the identification label on the cable connected to the network port on the panel of the target device. The first photo and the second photo are identified to obtain the device information of the target device, which includes the attribute information and network port information of the target device.

[0076] The human-computer interaction module 4021 is used to collect the first operation signal and the second operation signal input by the user.

[0077] The communication module 4023 is used to send a first operation signal and a second operation signal to the identification module 4011; and to receive a first operation instruction and a second operation instruction sent by the identification module 4011.

[0078] The camera module 4022 is used to respond to the first operation command and the second operation command to take a first photo and a second photo. The first photo is obtained by taking a photo of the panel of the target device, and the second photo is obtained by taking a photo of the identification label on the cable connected to the network port on the panel of the target device.

[0079] The communication module 4023 is used to send the first photo and the second photo to the identification module 4011.

[0080] In some embodiments, the identification module 4011 is further configured to identify the first operation signal and generate a first operation instruction corresponding to the first operation signal, and to identify the second operation signal and generate a second operation instruction corresponding to the second operation signal.

[0081] In some embodiments, the scanning device 402 further includes a display module 4024;

[0082] The communication module 4023 is used to receive the device information of the target device sent by the identification module 4011, and / or the device information of N devices in the database 4013, where N devices are devices in the target system other than the target device, and N is a positive integer;

[0083] The display module 4024 is used to display the device information of the target device, and / or the device information of N devices.

[0084] In some embodiments, the identification module 4011 is further configured to receive a third operation signal sent by the scanning device 402, identify the third operation signal and generate first supplementary information of the target device, and update the device information of the target device in the database 4013 according to the first supplementary information, wherein the third operation signal is triggered by the user according to the device information of the target device; and / or receive a fourth operation signal sent by the scanning device 402, identify the fourth operation signal and generate second supplementary information of the target device, and update the device information of the target device in the database 4013 according to the second supplementary information, wherein the fourth operation signal is triggered by the user according to the device information of N devices.

[0085] In some implementations, the network topology analysis module 4012 is specifically used to determine devices belonging to the same target system based on the system identifier and location information of each device in the database 4013; for each device belonging to the same target system, each device is sequentially used as a target device, and each network port of the target device is analyzed based on the device information of the target device.

[0086] In some implementations, each network port of the target device is sequentially designated as the target port. The network topology analysis module 4012 is specifically used to determine whether a target port is connected to a cable; if the target port is not connected to a cable, the target port is set to idle; if the target port is connected to a cable, the module determines whether the peer port of the target port is idle; if the peer port is not idle, the module determines whether the physical connection between the peer port and the target port matches; if they do not match, the module determines that the target port has an anomaly; if they match, the module determines that the target port does not have an anomaly; if the peer port is idle, the module establishes a physical connection between the target port and the peer port.

[0087] In some embodiments, the scanning device 402 is a head-mounted device, and the display module 4024 is used to display a real image and a digital image, with the digital image superimposed on the real image, and the digital image including device information of the target device.

[0088] The network physical topology verification system provided in this application embodiment consists of a network device 401 and a scanning device 402. The network device 401 includes an identification module 4011, a network topology analysis module 4012, and a database 4013. The scanning device 402 includes a human-computer interaction module 4021, a camera module 4022, a communication module 4023, and a display module 4024. The identification module 4011 acquires device information, the network topology analysis module 4012 obtains analysis results, the database 4013 stores the device information, the human-computer interaction module 4021 obtains specific requests, the camera module 4022 acquires images, and the display module 4024 displays device information. Thus, the network physical topology verification system utilizes the interaction between the various modules of the network device and the various modules of the scanning device to obtain the network physical topology map of the system to be verified in a highly efficient, accurate, reliable, and easy-to-use manner. On the one hand, it can be used by the actual construction personnel of the system to be verified to troubleshoot network topology faults, and on the other hand, it provides an independent and objective verification method for third-party personnel.

[0089] Those skilled in the art should understand that Figure 4 The implementation functions of each module in the system for verifying the physical topology of the network shown can be understood by referring to the relevant descriptions of the aforementioned methods. Figure 4 The functions of each module in the system shown for verifying the physical topology of a network can be implemented through programs running on a processor or through specific logic circuits.

[0090] The technical solutions of the embodiments of this application are illustrated below with specific application examples.

[0091] Currently, checking the correctness and compliance of a system's network physical topology in a data center mainly relies on manual verification of the labels at both ends of the cables, requiring two people to use cable testers. Given the large number of devices and fiber optic cables in a data center, manually checking each cable is difficult, error-prone, and extremely inefficient. Furthermore, in certain special cases, third-party verification is necessary, making it unsuitable for the system's developers. Therefore, a more efficient, accurate, and user-friendly verification method is urgently needed. To address the problems of manual, error-prone, and inefficient manual verification, this application provides a highly efficient, accurate, and user-friendly verification method. It aims to collect information such as photos of actual network connections and utilize artificial intelligence image and text recognition technology, speech recognition and synthesis technology, and efficient algorithm processing to provide system developers and independent third parties with a highly efficient, accurate, reliable, and easy-to-use method for verifying the system's network physical topology.

[0092] Based on the foregoing embodiments, Figure 5 This is a schematic diagram of the system architecture for verifying network physical topology provided in the embodiments of this application. Figure 2 .like Figure 5 As shown, the system includes n scanning devices located at n positions. Each scanning device is a head-mounted glasses-like scanning device (hereinafter referred to as "scanning device"). It interacts with other modules via 4G / 5G base stations or WIFI. The system also includes a database, an AI image and text object recognition module, an AI speech recognition and synthesis module, and a network topology automatic generation algorithm module. The database, AI image and text object recognition module, AI speech recognition and synthesis module, and network topology automatic generation algorithm module are equivalent to the relevant functional modules in the aforementioned network devices. The AI ​​image and text object recognition module and the AI ​​speech recognition and synthesis module are equivalent to the aforementioned recognition module, and the network topology automatic generation algorithm module is equivalent to the aforementioned network topology analysis module. Figure 6 This is a schematic diagram of the structural composition of the scanning device provided in the embodiments of this application. Figure 6 As shown, the scanning device is a head-mounted glasses-like device, including a camera lens module, focus adjustment buttons (zoom in, zoom out), a microphone and / or earphone module, two lenses, an imaging and / or projection device, human-computer interaction input buttons (up, down, confirm), a 4G / 5G wireless cellular communication module, a WIFI module, and a micro motherboard. The camera lens module is located in the middle of the lenses, equivalent to the aforementioned camera module; the camera lens module has two focus adjustment buttons for controlling the camera focus, one for zooming in and the other for zooming out, located on the left eye socket; the microphone and / or earphone module are located on both sides of the eye socket; the two lenses are transparent, allowing observation of objects and supporting image display; the scanning device's "lens" houses the imaging and / or projection device, and the two lenses and the imaging and / or projection device are equivalent to the aforementioned display module; the human-computer interaction input... There are three input buttons: an up button, a down button, and a confirmation button. These buttons can be used to adjust volume and / or select menu options on the digital screen, and their specific functions can be configured according to actual needs; this application does not impose specific limitations on this. A 4G / 5G wireless cellular communication module and a Wi-Fi module are used for communication, equivalent to the aforementioned communication module. The focus adjustment button, microphone, and / or headphone module, along with the input buttons, collectively correspond to the aforementioned human-computer interaction module. Based on this, the method for verifying network physical topology provided in the embodiments of this application is further explained.

[0093] After wearing the scanning device, inspectors can send a "take a picture" voice command to the camera lens module via the microphone and / or earphone module. The scanning device then sends the received voice command to the backend AI speech recognition and synthesis module, which automatically recognizes the corresponding operation command. The AI ​​speech recognition and synthesis module then transmits the operation command back to the scanning device, controlling the camera lens module to take a picture. After the camera lens module takes the picture, the scanning device sends the photo to the backend AI image text object recognition module for AI recognition of objects in the photo. The AI ​​image text object recognition module then sends the results back to the scanning device, which displays them on the lens. Similarly, inspectors can speak other information via the microphone and / or earphone module. The scanning device sends the received "voice information" to the backend AI speech recognition and synthesis module, which automatically recognizes the corresponding "text information" and then transmits the "text information" back to the scanning device.

[0094] Before inspectors begin verifying the physical topology of a system's network, a unique system ID is assigned to the system to be verified in the backend database. All devices belonging to this system are subsequently assigned this system ID, which serves as the unique identifier for the system. Simultaneously, the location information of the system to be verified is entered into the backend database. This location information gradually narrows down from a broad geographical area to a more precise room-like location. Examples include: the city where the server room is located, the street where the server room is located, the latitude and longitude of the server room, the building number of the server room, the room number, the rack row (column) number where the equipment of the system to be verified is located, the rack number, and the U-position within the rack. For each location information, if any one of these location elements differs, it is considered a different location. Specifically, when the location information of the devices belonging to the system to be verified differs, multiple location information entries are required.

[0095] When the inspectors begin their inspection, for each device in the system to be inspected (including possible switches, routers, firewalls, load balancers, servers, storage devices, etc.), they first select and assign complete location information (gradually refining from a broad geographical area to the rack unit within a room, as described earlier). The inspectors first take a view of the front (rear) panel of a particular device. They can see the real-time view of the camera module on the lens of the scanning device. After adjusting the focus appropriately, they speak the command "take a picture" through the microphone and / or earphone module. After the camera module takes the picture, the scanning device sends the photo to the backend AI image text object recognition module for AI recognition of the objects in the photo. The latter then sends a list of the recognized results (including information such as "device category, name, device ID, front / rear panel, network port type (optical port, Ethernet port) located on the panel, quantity, and occupancy status (port activation status)") back to the scanning device, which displays the information on the lens. Afterwards, the scanning device can prompt the inspector to take a picture of the label on the cable connected to the network port of the device currently being inspected, and send it to the backend AI image and text object recognition module for AI recognition. The recognition result is then returned to the scanning device, which displays it to the inspector. Afterwards, the scanning device can open the voice input interaction channel for the inspectors, who can supplement the relevant information of the device to be inspected through voice input (including: the assigned device ID number, other potentially missing information, or information not recognized by the AI ​​image and text object recognition module). At the same time, the head-mounted scanning device can present the inspectors with the relevant information of other components of the system to be inspected (including: device ID, front and rear panels, various optical ports / network ports, etc.) that already exist in the background database (i.e., the network physical topology information database of the system to be inspected) for the inspectors to make selections, so as to complete the physical connection matching of each occupied network interface of the device to be inspected with the port of the connected peer device. If a "local" occupied port is not matched with a "remote" port, it is temporarily set to "idle" and can be further processed by the algorithm in the next stage of the "automatic network topology generation algorithm" execution phase.

[0096] After the above work is completed, the device being verified (including all its information) is stored in the background database, and the verification of this device is completed. The verification personnel continue to repeat the above steps to verify the next device in the system to be verified, until all devices are verified and saved in the background database.

[0097] Once all components of the system under verification have been verified, the verification personnel use automated methods, including voice commands, real-time commands, timed commands, and command programming, to automatically invoke a dedicated "network topology automatic generation algorithm module" in the background. This module processes information from the database automatically. If everything is correct, a topology diagram reflecting the physical connections of the network under verification is generated. If there are inconsistencies, such as a device's "local" port cable label indicating it's occupied, but the "peer" port of the interconnected cable is actually free; or the actual cable label on a device's "local" port doesn't match the actual "peer" port of the interconnected cable, an error alarm is output. This allows the verification personnel to clearly see whether the physical topology of the network under verification is accurate.

[0098] Figure 7 This is a schematic flowchart of a method for verifying network physical topology provided in an embodiment of this application. Figure 2 ;like Figure 7 As shown, the method for verifying the network physical topology includes the following steps:

[0099] Step 701: Determine whether the devices belong to the same system ID.

[0100] Before step 701, it is necessary to obtain the device information of each device in the system to be verified and store it in the database. The specific process of obtaining the device information of each device is as described above and will not be repeated here. Before starting the network physical topology verification of a certain system, a unified system ID number will be assigned to the system to be verified in the background database. All devices belonging to the system to be verified will be assigned this system ID number. Based on the system ID number, it is determined whether they belong to the same system ID. If they are devices with the same system ID, proceed to step 702; otherwise, continue to step 701 to determine the next device.

[0101] Step 702: Construct different "output result areas" for the devices in different location areas.

[0102] The output results area is used to display and / or store the analysis results of the device. In the future, it can be used to display the analysis results on the terminal, so that the user can see the analysis results of each area. One output results area can correspond to one device, multiple devices, or a system to be verified. The specific settings of the output results area can be set according to the actual situation, and this application does not make specific limitations on this.

[0103] Step 703: Perform algorithm processing for each device.

[0104] Each device can be processed by the aforementioned network topology automatic generation algorithm module. If there are devices in the system to be checked that have not yet been analyzed, steps 704 to 711 are executed. If all devices in the system to be checked have been analyzed, steps 712 to 714 are executed.

[0105] Step 704: Create a "Network Entity" for the device in the "Output Results Area" of its location.

[0106] For example, create a new network entity 1 in the output results area 1 and set its attributes, including: name, ID, type, etc. Then, you can add the corresponding analysis results to network entity 1.

[0107] Step 705: Analyze each network port (including front and rear panels) of each device one by one.

[0108] If any ports have not yet been analyzed, proceed to steps 706 to 711. If all ports have been analyzed, return to step 703 to analyze the next device.

[0109] Step 706: Determine whether the above network port is not connected to a cable.

[0110] If the above network port is not connected to a cable, proceed to step 707; if the above network port is connected to a cable, proceed to steps 708 to 711.

[0111] Step 707: In the "Output Results Area", set the port of the "Network Entity" to "Idle".

[0112] Step 708: For the above network ports, determine whether the physical connection port on the other end is idle.

[0113] For a network port with a connected cable, determine whether the physical connection port on the other end is idle. If it is idle, proceed to step 709; otherwise, proceed to steps 710 to 711.

[0114] Step 709: For the above network port, establish a link connection with the device to which the physical connection port of its counterpart belongs in the "Output Result Area".

[0115] For network ports where the peer physical connection port is idle, establish a connection with the device to which the peer physical connection port belongs in the "Output Result Area". Then return to step 705 to determine the status of the next port.

[0116] Step 710: Determine whether the physical connection between the peer physical connection port and the currently analyzed network port is consistent.

[0117] For network ports where the physical connection port of the peer is not idle, determine whether the physical connection between the physical connection port of the peer and the network port currently being analyzed is consistent. If they are inconsistent, proceed to step 711. If they are consistent, return to step 705 to determine the next port.

[0118] Step 711: Generate a critical warning.

[0119] A critical warning is generated for ports where the physical connection between the peer's physical connection port and the currently analyzed network port is inconsistent.

[0120] Step 712: Are there any alarms?

[0121] After all devices have been analyzed, determine if there are any alarms, i.e., whether there were any previous warnings. If there are no alarms, proceed to step 713; otherwise, proceed to step 714.

[0122] Step 713: Output a report of the network physical topology results of the system to be checked.

[0123] For systems under investigation that do not generate any alarms, output a network physical topology report of the system under investigation. The algorithm then terminates.

[0124] Step 714: Output a report of any errors.

[0125] For systems under investigation that have alarms, a report of erroneous results is output, which includes the aforementioned alarm information. The algorithm then terminates.

[0126] This verification method provides third-party personnel with a highly efficient, accurate, reliable, and easy-to-use way to verify the physical topology of a system's network.

[0127] Furthermore, the method in this application supports simultaneous verification by multiple people in different computer rooms, requiring only that each person wears a scanning device. The other backend modules, including the "database," "AI image text object recognition module," "AI speech recognition and synthesis module," and "network topology automatic generation algorithm module," are shared in the cloud and can be remotely shared. These cloud-based functional modules support collaborative mechanisms such as caching, queuing, multithreading, and resource locking to ensure that when requests originating from multiple scanning devices (including: scan data entry, data retrieval, AI recognition, and algorithm invocation) are received, the relevant processing resources can be accessed in an orderly manner.

[0128] It should be noted that, Figure 5 , Figure 6 The implementation functions of each module in the system and scanning device for verifying the network physical topology shown can be understood by referring to the relevant descriptions of the aforementioned methods.

[0129] The technical solutions provided in this application include an automatic network physical topology verification method, a network physical topology verification method supporting precise location information, a method supporting multi-person parallel collaboration for verifying cross-regional network physical topology, and an automatic network physical topology generation algorithm based on structured data records. The system network physical topology verification method of this application is highly efficient, accurate, reliable, and easy to use. On the one hand, it can be used by system builders to troubleshoot system network topology faults; on the other hand, it provides third-party personnel with an independent and objective verification method.
