Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a method, apparatus, device and storage medium for identifying network interface card (NIC) types. Background Technology

[0002] With the rapid development of servers and the diversification of usage scenarios, more and more functions need to be integrated into servers, and more and more components also need to be adapted to increase selectivity. These adaptations of different functions and components continuously improve the user experience of servers and meet the needs of more and more scenarios. For example, OCP (Open Compute Project) network interface cards (NICs) are a very common component in servers. Due to their advantages such as easy installation, high scalability, and form factor, their use is becoming more and more widespread, and the types of NICs are also constantly increasing.

[0003] Currently, network cards (NICs) on servers are typically identified through the BMC (Baseboard Management Controller). The specific identification process is as follows: After the server boots up, the BIOS (Basic Input Output System) first sends the NIC asset information to the BMC. Then, the BMC compares the information transmitted by the BIOS with the NIC information in a pre-stored array to determine the selected NIC type. Further, it determines whether the NIC supports NCSI (Network Controller Sideband Interface, a protocol defined for communication between the main controller's management controller and the NIC), the method of obtaining NIC information, and the NIC name. Finally, based on the determined acquisition method, it reads the corresponding NIC's register temperature for later heat dissipation control.

[0004] However, as the number of network cards that need to be adapted increases, the array capacity also becomes larger and more disordered, which increases the difficulty of subsequent development. The time and space complexity required to determine the network card type will also increase, thereby reducing the network card identification efficiency. In addition, as the number of network card types continues to increase, the maintenance cost of the array will also gradually increase. Furthermore, excessively long identification time will cause the display of network card information after the system boots up to be too slow, affecting the user experience and the performance requirements of the network card used in the server.

[0005] In summary, how to quickly identify different types of network interface cards (NICs) is a problem that still needs to be further solved in this field. Summary of the Invention

[0006] In view of this, the purpose of this application is to provide a network interface card (NIC) type identification method, apparatus, device, and storage medium, which can significantly reduce the number of array queries during NIC identification, improve NIC identification efficiency, and facilitate subsequent array maintenance. The specific solution is as follows:

[0007] Firstly, this application discloses a method for identifying network interface card (NIC) types, including:

[0008] The asset information of the target network interface card to be identified is obtained to obtain the target asset information; wherein, the target asset information includes the device identifier, manufacturer identifier and subsystem identifier of the target network interface card;

[0009] Based on the device identifier of the target network card in the target asset information, the target network card type array corresponding to the target network card is determined from multiple pre-created network card type arrays; wherein, different network card type arrays correspond to different device identifiers;

[0010] Check if there exists an identifier in the target network interface card type array that is the same as the manufacturer identifier of the target network interface card;

[0011] If there is an identifier in the target network interface card (NIC) type array that is the same as the manufacturer identifier of the target NIC, then the NIC type corresponding to the manufacturer identifier of the target NIC in the target NIC type array is taken as the NIC type of the target NIC, and the target NIC type is obtained.

[0012] If there is no identifier in the target network card type array that is the same as the manufacturer identifier of the target network card, then search for an identifier in the target network card type array that is the same as the subsystem identifier of the target network card.

[0013] If there is an identification code in the target network card type array that is the same as the subsystem identification code of the target network card, then the network card type corresponding to the subsystem identification code of the target network card in the target network card type array is taken as the network card type of the target network card, and the target network card type is obtained.

[0014] Optionally, the subsystem identification code includes a subsystem manufacturer identification code and a subsystem device identification code;

[0015] Accordingly, if the target network interface card (NIC) type array contains an identification code that is identical to the subsystem identification code of the target NIC, then the NIC type corresponding to the subsystem identification code of the target NIC in the target NIC type array is taken as the NIC type of the target NIC, including:

[0016] If there is an identification code in the target network card type array that is the same as the subsystem manufacturer identification code of the target network card, then the network card type in the target network card type array that corresponds to the subsystem manufacturer identification code of the target network card shall be used as the network card type of the target network card;

[0017] If there is an identification code in the target network card type array that is the same as the subsystem device identification code of the target network card, then the network card type in the target network card type array that corresponds to the subsystem device identification code of the target network card is taken as the network card type of the target network card.

[0018] Optionally, before obtaining the asset information of the target network interface card to be identified, the process further includes:

[0019] Collect asset information of different types of network interface cards (NICs) to obtain historical asset information; the historical asset information includes the device identifier, manufacturer identifier, and subsystem identification code of each of the different types of NICs.

[0020] The historical asset information is sent to the baseboard management controller via the basic input / output system.

[0021] The historical asset information is classified according to different device identifiers by the baseboard management controller to obtain multiple classified asset information;

[0022] Based on the asset information after each classification, create corresponding network card type arrays for each of the different types of network cards to obtain multiple network card type arrays;

[0023] All network interface card (NIC) type arrays are stored in the electrically erasable programmable read-only memory (EEPROM) of the motherboard;

[0024] Accordingly, determining the target network interface card (NIC) type array corresponding to the target NIC from a pre-created array of multiple NIC type arrays based on the device identifier of the target NIC in the target asset information includes:

[0025] Read all the network interface card (NIC) type arrays from the electrically erasable programmable read-only memory, and determine the target NIC type array corresponding to the target NIC from a plurality of pre-created NIC type arrays based on the device identifier of the target NIC in the target asset information.

[0026] Optionally, after creating corresponding network interface card (NIC) type arrays for each of the different types of NICs based on the classified asset information, and obtaining multiple NIC type arrays, the method further includes:

[0027] Determine the device identifier corresponding to each of the classified asset information;

[0028] The corresponding network interface card (NIC) type arrays are named according to the naming convention of the device identifiers corresponding to the classified asset information, so as to obtain the array name corresponding to each NIC type array.

[0029] Optionally, determining the target network interface card (NIC) type array corresponding to the target NIC from a pre-created array of multiple NIC type arrays based on the device identifier of the target NIC in the target asset information includes:

[0030] Check whether the array name corresponding to the multiple pre-created network interface card type arrays contains the device identifier from the target asset information;

[0031] If the array name corresponding to multiple network interface card (NIC) type arrays contains the device identifier from the target asset information, then the corresponding NIC type array is used as the target NIC type array for the target NIC.

[0032] Optionally, the network interface card (NIC) type identification method further includes:

[0033] Determine whether the target network card supports the network controller sideband interface communication mode;

[0034] If the target network card supports the network controller sideband interface communication mode, then the temperature information acquisition method and feature information of the target network card are determined, and the temperature information of the target network card is acquired through the temperature information acquisition method and the feature information.

[0035] Optionally, the temperature information acquisition method can be any one of the following: a first information acquisition method based on an integrated circuit bus, a second information acquisition method based on a management component transmission protocol at the upper layer and a fast peripheral component interconnection protocol at the lower hardware interface, and a third information acquisition method based on a management component transmission protocol at the upper layer and an integrated circuit bus at the lower hardware interface.

[0036] Secondly, this application discloses a network interface card (NIC) type identification device, comprising:

[0037] The information acquisition module is used to acquire asset information of the target network card to be identified, and obtain target asset information; wherein, the target asset information includes the device identifier, manufacturer identifier and subsystem identification code of the target network card;

[0038] An array determination module is used to determine the target network card type array corresponding to the target network card from a pre-created array of multiple network card type arrays based on the device identifier of the target network card in the target asset information; wherein, different network card type arrays correspond to different device identifiers;

[0039] The first search module is used to search whether there is an identifier in the target network card type array that is the same as the manufacturer identifier of the target network card;

[0040] The first type determination module is used to determine the target network card type by taking the network card type corresponding to the manufacturer identifier of the target network card in the target network card type array as the network card type of the target network card if there is an identifier in the target network card type array that is the same as the manufacturer identifier of the target network card.

[0041] The second search module is used to search for an identifier in the target network card type array that is the same as the subsystem identifier of the target network card if there is no identifier in the target network card type array that is the same as the manufacturer identifier of the target network card.

[0042] The second type determination module is used to determine the target network card type by taking the network card type corresponding to the subsystem identification code of the target network card in the target network card type array as the network card type of the target network card if there is an identification code in the target network card type array that is the same as the subsystem identification code of the target network card.

[0043] Thirdly, this application discloses an electronic device, including a processor and a memory; wherein, when the processor executes a computer program stored in the memory, it implements the aforementioned network card type identification method.

[0044] Fourthly, this application discloses a computer-readable storage medium for storing a computer program; wherein, when the computer program is executed by a processor, it implements the aforementioned network card type identification method.

[0045] As can be seen, this application first obtains the asset information of the target network interface card (NIC) to be identified, thereby obtaining the target asset information. The target asset information includes the device identifier, manufacturer identifier, and subsystem identifier of the target NIC. Then, based on the device identifier of the target NIC in the target asset information, it determines the target NIC type array corresponding to the target NIC from multiple pre-created NIC type arrays. Different NIC type arrays correspond to different device identifiers. Next, it checks whether there exists an identifier in the target NIC type array that is identical to the manufacturer identifier of the target NIC. If there is an identifier in the target NIC type array that is identical to the manufacturer identifier of the target NIC... If the target network interface card (NIC) type is determined by the identifier, the NIC type corresponding to the manufacturer identifier of the target NIC in the target NIC type array is used as the NIC type of the target NIC. If no identifier matching the manufacturer identifier exists in the target NIC type array, then an identifier matching the subsystem identifier of the target NIC is searched in the target NIC type array. If an identifier matching the subsystem identifier exists in the target NIC type array, then the NIC type corresponding to the subsystem identifier of the target NIC in the target NIC type array is used as the NIC type of the target NIC. This application divides the network interface card (NIC) type array into multiple NIC type arrays by using device identifiers. When identifying the NIC type, the target NIC type array corresponding to the target NIC is first determined based on the device identifier of the target NIC. Then, the NIC type of the target NIC is determined from the target NIC type array based on the manufacturer identifier and subsystem identifier of the target NIC. Compared with the traditional method of comparing four parameters simultaneously—device identifier, manufacturer identifier, subsystem manufacturer identifier, and subsystem device identifier—this application only needs to compare the manufacturer identifier and subsystem identifier one by one. Since the number of parameters to be compared is reduced, the number of array queries during NIC identification can be greatly reduced, improving the efficiency of NIC identification. In addition, since the arrays are classified, the data volume of a single array is reduced, which facilitates the maintenance of the arrays in the later stages. Attached Figure Description

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] This application discloses a method for identifying network interface card (NIC) types. See also... Figure 1 As shown, the method includes:

[0053] Step S11: Obtain the asset information of the target network card to be identified, and obtain the target asset information; wherein, the target asset information includes the device identifier, manufacturer identifier and subsystem identification code of the target network card.

[0054] In this embodiment, when it is necessary to identify the network card type of a target network card, such as an OCP (Open Compute Project) network card or a PCIe (peripheral component interconnect express) network card, the asset information of the target network card to be identified is first obtained. Specifically, the asset information may include the device identifier (Device ID), vendor identifier (Vendor ID), and subsystem identifier (SDID) of the target network card to be identified. The subsystem identifier includes, but is not limited to, the subsystem vendor identifier (SVID) and the subsystem device identifier (SDID).

[0055] Step S12: Based on the device identifier of the target network card in the target asset information, determine the target network card type array corresponding to the target network card from a plurality of pre-created network card type arrays; wherein, different network card type arrays correspond to different device identifiers.

[0056] In this embodiment, after obtaining the asset information of the target network interface card (NIC) to be identified, the target NIC type array corresponding to the target NIC can be directly determined from multiple pre-created NIC type arrays based on the device identifier of the target NIC contained in the target asset information. It should be noted that different NIC type arrays correspond to different device identifiers (i.e., Device IDs).

[0057] In this embodiment, before obtaining the asset information of the target network interface card (NIC) to be identified, the method further includes: collecting asset information of different types of NICs to obtain historical asset information; the historical asset information includes the device identifier, manufacturer identifier, and subsystem identifier of each of the different types of NICs; sending the historical asset information to the baseboard management controller through the basic input / output system; classifying the historical asset information according to the different device identifiers through the baseboard management controller to obtain multiple classified asset information; creating corresponding NIC type arrays for each of the different types of NICs based on each of the classified asset information to obtain multiple NIC type arrays; and storing all the NIC type arrays in the electrically erasable programmable read-only memory (EEPROM) of the motherboard. In this embodiment, before identifying the target network card, the server can collect historical asset information of different types of network cards in advance. Then, the server sends the collected historical asset information to the Baseboard Management Controller (BMC) through the Basic Input Output System (BIOS). After receiving the historical asset information, the BMC classifies the historical asset information according to the different device identifiers (i.e., Device IDs) to obtain multiple classified asset information. Furthermore, based on each of the classified asset information, a corresponding network card type array is created for each of the different types of network cards. That is, asset information with the same Device ID is grouped into one category and recorded as an array, thus obtaining multiple network card type arrays. In addition, for the convenience of subsequent use, all the above network card type arrays can be stored in the electrically erasable programmable read-only memory (EEPROM) of the motherboard. The historical asset information may include, but is not limited to, the device identifier, manufacturer identifier, and subsystem identification code of each of the different types of network cards.

[0058] Furthermore, after creating corresponding network interface card (NIC) type arrays for each of the different types of NICs based on the categorized asset information, resulting in multiple NIC type arrays, the process may further include: determining the device identifier corresponding to each of the categorized asset information; and naming the corresponding NIC type arrays according to a naming convention that includes the device identifier corresponding to the categorized asset information, to obtain the array name corresponding to each NIC type array. For example, when the device identifier corresponding to the categorized asset information is / dev / eth0, the corresponding NIC type array can be named according to the naming format / dev / eth0+ncsi+map, thereby obtaining the corresponding array name.

[0059] Accordingly, determining the target network interface card (NIC) type array corresponding to the target NIC from a pre-created plurality of NIC type arrays based on the device identifier of the target NIC in the target asset information may specifically include: reading all the NIC type arrays from the electrically erasable programmable read-only memory (EEPROM), and determining the target NIC type array corresponding to the target NIC from the pre-created plurality of NIC type arrays based on the device identifier of the target NIC in the target asset information. That is, when performing NIC type identification, it is necessary to first read the pre-created NIC type array containing asset information for multiple different types of NICs from the EEPROM, and then determine the target NIC type array that has the same device identifier as the target NIC from the plurality of NIC type arrays based on the device identifier of the target NIC.

[0060] In one specific implementation, determining the target network interface card (NIC) type array corresponding to the target NIC from a pre-created plurality of NIC type arrays based on the device identifier of the target NIC in the target asset information may specifically include: checking whether the array names corresponding to the pre-created plurality of NIC type arrays contain the device identifier from the target asset information; if the array names corresponding to the plurality of NIC type arrays contain the device identifier from the target asset information, then the corresponding NIC type array is used as the target NIC type array of the target NIC. In this embodiment, it is possible to first check whether the array names corresponding to the pre-created plurality of NIC type arrays contain the device identifier of the target NIC in the target asset information; if the array names corresponding to the plurality of NIC type arrays contain the device identifier of the target NIC in the target asset information, then the corresponding NIC type array is used as the target NIC type array of the target NIC.

[0061] Step S13: Check if there is an identifier in the target network card type array that is the same as the manufacturer identifier of the target network card.

[0062] In this embodiment, after determining the target network card type array corresponding to the target network card from multiple pre-created network card type arrays, the system first searches the target network card type array to see if there is an identifier that is the same as the vendor identifier (i.e., Vendor ID) of the target network card.

[0063] Step S14: If there is an identifier in the target network card type array that is the same as the manufacturer identifier of the target network card, then the network card type in the target network card type array that corresponds to the manufacturer identifier of the target network card is taken as the network card type of the target network card, and the target network card type is obtained.

[0064] In this embodiment, if there is an identifier in the target network card type array that is the same as the manufacturer identifier of the target network card, then the network card type corresponding to the manufacturer identifier of the target network card in the target network card type array is directly used as the network card type of the target network card, thereby obtaining the target network card type.

[0065] Step S15: If there is no identifier in the target network card type array that is the same as the manufacturer identifier of the target network card, then check if there is an identifier in the target network card type array that is the same as the subsystem identifier of the target network card.

[0066] In this embodiment, if there is no identifier in the target network card type array that is the same as the manufacturer identifier of the target network card, then it is possible to further search in the target network card type array for an identifier that is the same as the subsystem identifier of the target network card.

[0067] Step S16: If there is an identification code in the target network card type array that is the same as the subsystem identification code of the target network card, then the network card type in the target network card type array that corresponds to the subsystem identification code of the target network card is taken as the network card type of the target network card, and the target network card type is obtained.

[0068] In this embodiment, if there is an identification code in the target network card type array that is the same as the subsystem identification code of the target network card, then the network card type in the target network card type array that corresponds to the subsystem identification code of the target network card is taken as the network card type of the target network card, thereby obtaining the target network card type.

[0069] Furthermore, after identifying the network interface card (NIC) type of the target NIC, the process may further include: determining whether the target NIC supports the Network Controller Sideband Interface (NCSI) communication mode; if the target NIC supports the NCSI communication mode, then determining the temperature information acquisition method and characteristic information of the target NIC, and acquiring the temperature information of the target NIC using the temperature information acquisition method and the characteristic information. In this embodiment, after identifying the NIC type, it is further possible to determine whether the target NIC supports the NCSI communication mode. If the target NIC supports the NCSI communication mode, then determining the temperature information acquisition method and characteristic information of the target NIC, and then acquiring the temperature information of the target NIC using the temperature information acquisition method and the characteristic information.

[0070] Specifically, the temperature information acquisition method can be any one of the following: a first information acquisition method based on an integrated circuit bus (I2C, Inter-Integrated Circuit); a second information acquisition method based on a management component transport protocol at the upper layer and a fast peripheral component interconnect protocol (MCTP-OVER-PCIE) at the lower hardware interface; or a third information acquisition method based on a management component transport protocol at the upper layer and an integrated circuit bus (MCTP-OVER-I2C) at the lower hardware interface.

[0071] As can be seen, this embodiment first obtains the asset information of the target network interface card (NIC) to be identified to obtain target asset information. The target asset information includes the device identifier, manufacturer identifier, and subsystem identifier of the target NIC. Then, based on the device identifier of the target NIC in the target asset information, the target NIC type array corresponding to the target NIC is determined from multiple pre-created NIC type arrays. Different NIC type arrays correspond to different device identifiers. Next, it checks whether there is an identifier in the target NIC type array that is the same as the manufacturer identifier of the target NIC. If there is an identifier in the target NIC type array that is the same as the manufacturer identifier of the target NIC... If the target network interface card (NIC) type is not found in the target NIC type array, then the NIC type corresponding to the manufacturer identifier of the target NIC is taken as the NIC type of the target NIC. If the target NIC type array does not contain an identifier that is the same as the manufacturer identifier of the target NIC, then the target NIC type array is searched for an identifier that is the same as the subsystem identifier of the target NIC. If the target NIC type array contains an identifier that is the same as the subsystem identifier of the target NIC, then the NIC type corresponding to the subsystem identifier of the target NIC is taken as the NIC type of the target NIC. This application embodiment divides the network interface card (NIC) type array into multiple NIC type arrays by using device identifiers. When identifying the NIC type, the target NIC type array corresponding to the target NIC is first determined based on the device identifier of the target NIC. Then, the NIC type of the target NIC is determined from the target NIC type array based on the manufacturer identifier and subsystem identifier of the target NIC. Compared to the traditional method of comparing four parameters simultaneously—device identifier, manufacturer identifier, subsystem manufacturer identifier, and subsystem device identifier—this application only needs to compare the manufacturer identifier and subsystem identifier one by one. Since the number of parameters to be compared is reduced, the number of array queries during NIC identification can be greatly reduced, improving the efficiency of NIC identification. In addition, since the arrays are classified, the data volume of a single array is reduced, which facilitates the maintenance of the arrays in the later stages.

[0072] This application discloses a specific method for identifying network interface card (NIC) types. See also... Figure 2 As shown, the method includes:

[0073] Step S21: Obtain the asset information of the target network card to be identified, and obtain the target asset information; wherein, the target asset information includes the device identifier, manufacturer identifier and subsystem identification code of the target network card, and the subsystem identification code includes the subsystem manufacturer identification code and the subsystem device identification code.

[0074] In this embodiment, the asset information of the target network card to be identified is first obtained, resulting in target asset information including device identifier, vendor identifier, subsystem vendor identifier (SVID), and subsystem device identifier (SDID).

[0075] Step S22: Based on the device identifier of the target network card in the target asset information, determine the target network card type array corresponding to the target network card from a plurality of pre-created network card type arrays; wherein, different network card type arrays correspond to different device identifiers.

[0076] Step S23: Check if there is an identifier in the target network card type array that is the same as the manufacturer identifier of the target network card.

[0077] Step S24: If there is an identifier in the target network card type array that is the same as the manufacturer identifier of the target network card, then the network card type in the target network card type array that corresponds to the manufacturer identifier of the target network card is taken as the network card type of the target network card, and the target network card type is obtained.

[0078] Step S25: If there is no identifier in the target network card type array that is the same as the manufacturer identifier of the target network card, then check if there is an identifier in the target network card type array that is the same as the subsystem identifier of the target network card.

[0079] Step S26: If there is an identification code in the target network card type array that is the same as the subsystem manufacturer identification code of the target network card, then the network card type in the target network card type array that corresponds to the subsystem manufacturer identification code of the target network card is taken as the network card type of the target network card, and the target network card type is obtained.

[0080] In this embodiment, if there is an identification code in the target network card type array that is the same as the subsystem vendor identification code (SVID) of the target network card, then the network card type corresponding to the subsystem vendor identification code of the target network card in the target network card type array is directly used as the network card type of the target network card, thereby obtaining the target network card type.

[0081] Step S27: If there is an identification code in the target network card type array that is the same as the subsystem device identification code of the target network card, then the network card type in the target network card type array that corresponds to the subsystem device identification code of the target network card is taken as the network card type of the target network card, and the target network card type is obtained.

[0082] In this embodiment, if there is no identification code in the target network card type array that is the same as the subsystem vendor identification code (SVID) of the target network card, then it is further determined whether there is an identification code in the target network card type array that is the same as the subsystem device identification code (SDID) of the target network card. If there is, the network card type in the target network card type array that corresponds to the subsystem device identification code of the target network card is taken as the network card type of the target network card, thereby obtaining the target network card type.

[0083] For more detailed processing procedures of steps S22 to S25, please refer to the relevant content disclosed in the foregoing embodiments, which will not be repeated here.

[0084] As can be seen, the network interface card (NIC) type identification scheme proposed in this application pre-configures multiple NIC type arrays in the BMC identification code based on different Device IDs. When identifying the NIC type of a target NIC, it first matches a target NIC type array based on the NIC's Device ID, and then matches based on the Vendor ID. If no identifier matching the Vendor ID is found, it then matches the SVID and SDID one by one. Since a large array is split into multiple smaller arrays based on the Device ID, the amount of data for array matching is reduced, improving the efficiency of NIC identification. Furthermore, it facilitates the maintenance and management of each small data set. Since no hardware modifications are required, hardware costs are saved, while still meeting the performance requirements of NICs used in servers.

[0085] Accordingly, this application also discloses a network card type identification device, see [link to relevant documentation]. Figure 3 As shown, the device includes:

[0086] The information acquisition module 11 is used to acquire asset information of the target network card to be identified, and obtain target asset information; wherein, the target asset information includes the device identifier, manufacturer identifier and subsystem identification code of the target network card;

[0087] The array determination module 12 is used to determine the target network card type array corresponding to the target network card from a plurality of pre-created network card type arrays based on the device identifier of the target network card in the target asset information; wherein, different network card type arrays correspond to different device identifiers;

[0088] The first search module 13 is used to search whether there is an identifier in the target network card type array that is the same as the manufacturer identifier of the target network card;

[0089] The first type determination module 14 is used to determine the target network card type by taking the network card type corresponding to the manufacturer identifier of the target network card in the target network card type array as the network card type of the target network card if there is an identifier in the target network card type array that is the same as the manufacturer identifier of the target network card.

[0090] The second search module 15 is used to search for an identifier in the target network card type array that is the same as the subsystem identifier of the target network card if there is no identifier in the target network card type array that is the same as the manufacturer identifier of the target network card.

[0091] The second type determination module 16 is used to determine the target network card type by taking the network card type corresponding to the subsystem identification code of the target network card in the target network card type array as the network card type of the target network card if there is an identification code in the target network card type array that is the same as the subsystem identification code of the target network card.

[0092] The specific workflow of each of the above modules can be found in the relevant content disclosed in the foregoing embodiments, and will not be repeated here.

[0093] As can be seen, in this embodiment, the asset information of the target network card to be identified is first obtained to obtain the target asset information; wherein, the target asset information includes the device identifier, manufacturer identifier, and subsystem identifier of the target network card; then, based on the device identifier of the target network card in the target asset information, the target network card type array corresponding to the target network card is determined from a plurality of pre-created network card type arrays; wherein, different network card type arrays correspond to different device identifiers; next, it is checked whether there is an identifier in the target network card type array that is the same as the manufacturer identifier of the target network card; if there is an identifier in the target network card type array that is the same as the manufacturer identifier of the target network card... If the target network interface card (NIC) has the same identifier as the target NIC, then the NIC type corresponding to the manufacturer identifier of the target NIC in the target NIC type array is taken as the NIC type of the target NIC, thus obtaining the target NIC type. If there is no identifier in the target NIC type array that is the same as the manufacturer identifier of the target NIC, then the target NIC type array is searched for an identifier that is the same as the subsystem identifier of the target NIC. If there is an identifier in the target NIC type array that is the same as the subsystem identifier of the target NIC, then the NIC type corresponding to the subsystem identifier of the target NIC in the target NIC type array is taken as the NIC type of the target NIC, thus obtaining the target NIC type. This application embodiment divides the network interface card (NIC) type array into multiple NIC type arrays by using device identifiers. When identifying the NIC type, the target NIC type array corresponding to the target NIC is first determined based on the device identifier of the target NIC. Then, the NIC type of the target NIC is determined from the target NIC type array based on the manufacturer identifier and subsystem identifier of the target NIC. Compared to the traditional method of comparing four parameters simultaneously—device identifier, manufacturer identifier, subsystem manufacturer identifier, and subsystem device identifier—this application only needs to compare the manufacturer identifier and subsystem identifier one by one. Since the number of parameters to be compared is reduced, the number of array queries during NIC identification can be greatly reduced, improving the efficiency of NIC identification. In addition, since the arrays are classified, the data volume of a single array is reduced, which facilitates the maintenance of the arrays in the later stages.
