In other words, the interfaces and devices that the network card can logically adapt to are fixed and unchanged (for example, if it is determined to use configuration A for the interface), and since the physical storage space of the network card is limited, the devices that the network card can adapt to are also limited.

[0041] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0042] First, some terms involved in the embodiments of the present application are explained below to facilitate understanding by those skilled in the art.

[0043] FPGA: Field Programmable Gate Array, field programmable gate array.

[0044] NIOS: A soft-core processor running on an (Intel Altera) FPGA.

[0045] AOC: Active Optical Cables, active cables, mostly refers to optical fiber, optical transmission medium.

[0046] DAC: Direct Attach Cable, direct cable, multi-finger copper cable, electrical signal transmission medium.

[0047] FEC: Applicable to high-speed communications (25G, 40G, 100G, especially 40G and 100G), it is an error correction technology.

[0048] The foregoing introduces some terminology concepts involved in the embodiments of the present application. The following introduces the technical features involved in the embodiments of the present application.

[0049] like Figure 1 As shown, the network card 102 may be set in a hardware device (such as the first device 101), and the second device 103 may be linked to the network card to achieve communication between the first device and the second device. The network card may refer to a smart network card.

[0050] The first device and the second device may be arranged in an Ethernet network, but this application does not impose any limitation on this.

[0051] In some embodiments, the first device may be a server in the Ethernet, and the second device may be other network cards or switches in the Ethernet to obtain other hardware devices, etc., which is not limited in this application.

[0052] In the related art, each network card hardware can be equipped with an Ethernet hard core. Ethernet is a computer local area network technology that specifies the content of the physical layer connection, electronic signals and media access layer protocol. It is the most commonly used local area network technology. The network card needs to transmit the received and sent data packets to the CPU for processing through Ethernet (protocol). Among them, the network card can also include an Ethernet interface controller (configurable interface) which is a dedicated circuit module. There will be a large number of (dozens to hundreds) registers that need to be configured to meet the requirements.

[0053] In related technologies, such as Figure 2 As shown, the network card 202 in the first device 201 (which may be a server, for example) may be configured with an ASIC chip 204 (a special integrated circuit), and the configuration information of the interface controller 203 (such as an Ethernet interface controller) may be fixed in the ASIC chip using physical logic, so that the interface controller 203 may be configured when necessary, thereby realizing a logical connection with other devices through the interface. However, the configuration information in this method is fixedly written in the ASIC chip through physical logic, and cannot be modified and reconfigured unless it is re-threaded, and this method occupies the physical storage space of the ASIC chip, so that the types of devices that the network card can adapt to are limited. Figure 2The method of using physical logic to configure related parameters is usually suitable for static configuration, that is, specifying a set of optimal parameters and writing them into the configuration process. The advantage of this method is simplicity, but the disadvantages are also obvious, such as limited compatibility and poor flexibility.

[0054] In this embodiment, if Figure 3 As shown, an FPGA (field programmable logic device) chip can be set in the network card 302 of the first device 301, and a soft-core processor 304 can be set in the FPGA chip, and then the configuration information of the interface controller can be written into the soft-core processor 304 in advance, so that the configuration information in the soft-core processor can be used to configure the interface controller 303 when needed.

[0055] In some embodiments, relevant parameters can be set through the internal control logic of the FPGA chip to achieve a smooth negotiation link with an external peer network card or switch device, thereby performing data interaction.

[0056] Figure 4 FIG. 1 is a diagram showing a device connection architecture according to an exemplary embodiment. Figure 4 As shown, a smart network card 402 can be installed on the first device 401 (such as a server), and the following two components can be configured on the smart network card 402: an interface controller 403 (such as an Ethernet interface controller) and a nios soft-core processor 404. The Ethernet controller is a hard-core IP provided by Intel, which can be instantiated and used directly in the project, and the nios soft-core processor is a configurable processor optimized for programmable logic developed based on C language. The second device 405 (such as a switch) can be connected to the network card 402 through the Ethernet controller 403 (including physical connection and logical link). The second device can be physically connected to the network card in advance through cables and interfaces; then the network card configures the connection interface so that the second device and the network card can be logically negotiated to link.

[0057] The specific process of the network card configuring the connection interface so that the second device and the network card can logically negotiate a link may include reference to the following embodiments.

[0058] Figure 5 The present invention is a flowchart of a method for configuring a network card according to an exemplary embodiment.

[0059] Reference Figure 5 The network card configuration method provided by the embodiment of the present disclosure may include the following steps.

[0060] Step S502, the network card determines the medium type of the cable that is physically connected to the network card in contact in response to the configuration instruction, the network card is provided with at least one configuration parameter group, the at least one configuration parameter group includes a first type of configuration parameter group, and the cable is used to physically connect the network card and the target device.

[0061] The above network card may refer to a smart network card, and the above smart network card may refer to a high-performance access card with a network processor as the core.

[0062] In some embodiments, when it is detected that the network card is powered on (ie, the device where the network card is located is powered on) or there is a cable plugging and unplugging operation on the network card or the interface controller of the network card is reset, a configuration instruction may be generated.

[0063] In some embodiments, the network card detects the media type of the cable directly connected to the network card in response to the configuration instruction. For example, the network card can detect the media type of the cable inserted into the network card. The above-mentioned cable can include an optical fiber cable, a copper cable, etc., and this application does not limit this.

[0064] In some embodiments, the cable can be used to physically connect the network card to a target device, which can be Figure 4 The second device 405 in FIG. 4. It is understandable that if the network card is to communicate with the target device, it is also necessary to control the network card to perform a logical negotiation link with the target device after the network card is physically connected with the target device.

[0065] In some embodiments, interface configuration information (such as at least one configuration parameter group) corresponding to all devices that need to be connected to the network card may be pre-stored in the network card.

[0066] It is understandable that if the same device is connected to the network card through different cables, the information in the corresponding interface configuration parameter group may be different. Therefore, the same device may correspond to different configuration parameter groups due to different connection cables.

[0067] Step S504: The network card determines a first type of configuration parameter group that matches the medium type of the cable from at least one configuration parameter group, wherein different medium types correspond to different types of configuration parameter groups.

[0068] In some embodiments, a first type of configuration parameter group matching the medium type of the cable may be determined from the at least one configuration parameter group.

[0069] Step S506: The network card traverses the first type of configuration parameter group and configures the physical connection interface between the network card and the cable so that the network card and the target device can perform a logical negotiation link.

[0070] In some embodiments, a traversal can be performed in the first type of configuration parameter group, and the traversal results can be used to configure the physical connection interface between the cable and the network card until a configuration parameter group matching the target device is found in the first type of configuration parameter group, so that the network card and the target device can perform a logical negotiation link.

[0071] The network card configuration method provided by the embodiment of the present disclosure realizes the logical link between the network card and the target device by identifying the medium type of the cable, finding the first type of configuration parameter group matching the cable medium type, traversing the first type of configuration parameter group, etc. The above embodiment realizes the dynamic configuration of the interface through the network card, and improves the logical compatibility between the network card and the target device.

[0072] Figure 6 The present invention is a flowchart of a method for configuring a network card according to an exemplary embodiment.

[0073] In some embodiments, the first type of configuration parameter group may include configuration parameter group one and configuration parameter group two.

[0074] refer to Figure 6 , the above network card configuration method may include the following steps.

[0075] Step S602, the network card determines the medium type of the cable that is physically connected to the network card in contact in response to the configuration instruction, the network card is provided with at least one configuration parameter group, the at least one configuration parameter group includes a first type of configuration parameter group, and the cable is used to physically connect the network card and the target device.

[0076] Step S604: The network card determines a first type of configuration parameter group that matches the medium type of the cable in at least one configuration parameter group, wherein the first type of configuration parameter group includes configuration parameter group one and configuration parameter group two, wherein different medium types correspond to different types of configuration parameter groups.

[0077] The network card will traverse the first type of configuration parameter group to configure the physical connection interface between the network card and the cable, which may specifically include the following steps.

[0078] Step S606: configure the physical connection interface between the network card and the cable by configuring a pair of parameter groups.

[0079] Step S608: If the negotiation link between the network card and the target device is unsuccessful under the configuration of the configuration parameter group 1, the physical connection interface between the network card and the cable is configured by continuing to use the configuration parameter group 2.

[0080] In some embodiments, if the network card fails to negotiate with the target device under the configuration of configuration parameter group one, configuration parameter group two is continued to be used to configure the physical connection interface between the network card and the cable.

[0081] In the above embodiment, the physical connection interface between the network card and the cable is configured by configuration parameter group 1 and configuration parameter group 2 in the first type configuration parameter group to implement a logical negotiation link between the network card and the target device, thereby improving the compatibility of the network card.

[0082] Figure 7 The present invention is a flowchart of a method for configuring a network card according to an exemplary embodiment.

[0083] In some embodiments, the above-mentioned configuration parameter group 1 may include at least two cable rate parameters and at least two coding error correction configuration parameters.

[0084] refer to Figure 7 The configuration method for configuring a network card by configuring a parameter group may include the following steps.

[0085] Step S702: When configuring the physical connection interface between the network card and the cable through a configuration parameter group, the network card switches between at least two cable rate parameters to determine a cable rate parameter suitable for the cable.

[0086] Step S704: When configuring the physical connection interface between the network card and the cable through the configuration parameter group, the network card also switches between at least two coding error correction configuration parameters to determine coding error correction configuration parameters suitable for the cable.

[0087] Step S706: If there is a cable rate parameter suitable for the cable among the at least two cable rate parameters and there is a coding error correction configuration parameter suitable for the cable among the at least two coding error correction configuration parameters, the physical connection interface between the network card and the cable is configured successfully.

[0088] In the above embodiment, the configuration of the physical connection interface between the network card and the cable is realized by switching the cable rate parameters and the coding error correction parameters, thereby determining whether the configuration of the physical connection interface between the network card and the cable is successful.

[0089] Figure 8 The present invention is a flowchart of a method for configuring a network card according to an exemplary embodiment.

[0090] In some embodiments, the network card may include an interface controller and a processor (eg, Figure 4 The interface controller 403 and the soft core processor 404 are shown).

[0091] refer to Figure 8 , the above network card configuration method may include the following process.

[0092] Step S802: In response to the configuration instruction, the processor of the network card detects through the interface controller whether the medium type of the cable physically connected to the network card is an optical fiber type or a copper type.

[0093] Step S804: The processor of the network card determines a first type of configuration parameter group corresponding to the optical fiber type or the copper type in at least one configuration parameter group.

[0094] Step S806: The processor of the network card traverses the first type of configuration parameter group and configures the interface controller of the network card so that the network card and the target device can perform a logical negotiation link.

[0095] In the above embodiment, on the one hand, at least one configuration parameter group is written into the processor, so that the configuration parameter group no longer occupies the physical content of the network card, thereby optimizing the physical memory usage of the network card; on the other hand, dynamic configuration of the interface is realized through the network card, thereby improving the logical compatibility between the network card and the target device.

[0096] Fig. 9 The present invention is a flowchart of a method for configuring a network card according to an exemplary embodiment.

[0097] In some embodiments, the network card may include a processor, which may be a read-write processor.

[0098] refer to Fig. 9 , the above network card configuration method may include the following steps.

[0099] Step S902, the network card determines the medium type of the cable that is physically connected to the network card in contact in response to the configuration instruction, the network card is provided with at least one configuration parameter group, the at least one configuration parameter group includes a first type of configuration parameter group, and the cable is used to physically connect the network card and the target device.

[0100] Step S904: The network card determines a first type of configuration parameter group that matches the medium type of the cable from at least one configuration parameter group, wherein different medium types correspond to different types of configuration parameter groups.

[0101] Step S906: The network card traverses the first type of configuration parameter group and configures the physical connection interface between the network card and the cable so that the network card and the target device can perform a logical negotiation link.

[0102] Step S908: When the network card traverses the first type of configuration parameter group to configure the physical connection interface between the network card and the cable and the configuration fails, a target configuration parameter group corresponding to the target device and the cable is obtained.

[0103] Step S910, write the target configuration parameter group corresponding to the target device and the cable into the processor in the network card, so that the processor configures the physical connection interface between the network card and the cable through the target configuration parameter group, so that the network card and the target device can perform a logical negotiation link.

[0104] The above embodiment can obtain the target configuration parameter group corresponding to the target device and write the target configuration parameter group into the processor of the network card when traversing at least one configuration parameter group and failing to configure the physical connection interface, so as to perform interface configuration on the cable corresponding to the target device (or a device of the same type as the target device) next time.

[0105] Fig.10 The present invention is a flowchart of a method for configuring a network card according to an exemplary embodiment.

[0106] In some embodiments, the above network card configuration method can be executed before the network card responds to the configuration instruction.

[0107] refer to Fig.10 , the above network card configuration method may include the following steps.

[0108] Step S1002: receiving device configuration parameters corresponding to at least one device, where the at least one device includes a target device.

[0109] Step S1004: generating at least one configuration parameter group according to different media types of the cable and device configuration parameters corresponding to at least one device, wherein the at least one configuration parameter group includes a first type configuration parameter group.

[0110] Step S1006: write at least one configuration parameter group into a processor of the network card, so that the network card configures the logical link of the network card, the cable, and the target device according to the at least one configuration parameter group.

[0111] In the above embodiment, the configuration parameters of all devices that may be connected to the network card can be dynamically written into the network card in advance, so that when the device is connected to the network card, the network card can dynamically configure the connection interface, thereby improving the compatibility of the network card.

[0112] Fig.11 The present invention is a flowchart of a method for configuring a network card according to an exemplary embodiment.

[0113] In some embodiments, Figure 4 As shown, the network card can be set on the first device (such as a server), and the network card can include an interface controller (such as an Ethernet interface controller) and a soft-core processor (such as a nios soft-core processor). The second device can be physically and logically connected to the network card through the interface controller.

[0114] In some embodiments, before executing the following network card configuration method, the configuration parameter groups corresponding to each device (such as a switch) that needs to be connected to the network card under different cable types (for example, optical fiber type cables and copper type cables) can be written into the network card through read-write technology.

[0115] refer to Fig.11 , the above network card configuration method may include the following steps.

[0116] S1101: The smart network card is powered on, the Ethernet controller is reset as a whole, or a cable hot plug is detected.

[0119] The nios soft-core processor controls the Ethernet controller to read relevant register parameters to detect the type of cable connected to the network card and determine whether it is DAC (copper cable) or AOC (optical fiber).

[0120] In some embodiments, if the cable is determined to be a fiber optic cable, steps S1103 to S1109 are executed; if the cable is determined to be a copper cable, steps S1110 to S1116 are executed.

[0121] Among them, the configuration parameter group corresponding to the optical fiber cable may include configuration parameter groups A1~An. When configuring the interface corresponding to the optical fiber cable, the configuration parameter groups A1~An can be traversed to configure the interface until a configuration parameter group that enables a successful logical link between the network card and the second device is found.

[0122] refer to Fig.11 , steps S1103 to S1109 may include the following process.

[0123] S1103, configure parameter group A1.

[0124] If an AOC cable is detected, the prepared parameter group A1 is configured.

[0125] S1104, switching of rate and error correction configuration parameters is supported, and determining whether the link is successful.

[0126] After the parameter configuration is completed, the cable rate (25G / 10G) and FEC (coding error correction) related configurations are switched. If the link with the current second device (such as a switch) is successful, the loop is exited, otherwise step S1105 is continued.

[0127] S1105, configure parameter group A2.

[0128] Similarly, if the connection with the current second device is successful through the configuration parameter group A2, the loop can be exited, otherwise the next round of parameter group configuration can be continued.

[0129] S1106, switching of rate and error correction configuration parameters is supported, and determining whether the link is successful.

[0130] S1107, perform rate and error correction configuration parameter support switching, and determine whether the link is successful.

[0131] S1108, configure parameter group An.

[0132] S1109, switching of rate and error correction configuration parameters is supported, and determining whether the link is successful.

[0133] It is understandable that, since docking training has been performed with all second devices in advance, the link will inevitably be successful on a certain set of parameters.

[0134] In some embodiments, the configuration parameter group corresponding to the copper cable may include configuration parameter groups B1 to Bn. When configuring the interface corresponding to the copper cable, the configuration parameter groups B1 to Bn may be traversed to configure the interface until a configuration parameter group is found that enables a successful logical link between the network card and the second device.

[0135] refer to Fig.11 , steps S1110 to S1116 may include the following process.

[0136] S1110, configure parameter group B1.

[0137] Similarly, if a DAC cable is detected, the prepared parameter group B1 is configured. The subsequent configuration process is similar to the above-mentioned AOC cable and will not be repeated here.

[0138] S1111, rate and error correction configuration parameter support switching is performed, and it is determined whether the link is successful.

[0139] S1112, configuration parameter group B2

[0140] S1113, switching of rate and error correction configuration parameters is supported, and determining whether the link is successful.

[0141] S1114, rate and error correction configuration parameter support switching is performed, and it is determined whether the link is successful.

[0142] S1115, configure parameter group Bn.

[0143] S1116, rate and error correction configuration parameter support switching is performed, and it is determined whether the link is successful.

[0144] In some embodiments, if a second device type is added midway, and all parameter groups corresponding to the second device and the cable medium type fail to link, it is necessary to obtain the configuration parameter group corresponding to the second device, write the configuration parameter group into the network card through coding, and re-execute Fig.11 The technical solution corresponding to the embodiment shown.
