[0047] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0049] At present, in the related art, the network card device based on the bonding mode establishes a bonding relationship between two ports of the same network card device, and then performs remote direct memory access with other devices. For details, please refer to Figure 1 A schematic diagram of a communication architecture of remote direct memory access of a related technology is shown.

[0050] For a clearer explanation, please refer to the following glossary:

[0051] Remote Direct Memory Access (RDMA) is one of the important supporting technologies for realizing the potential of DPU solutions. It is a computer network technology that allows two nodes on the network to directly access each other's memory and complete data communication without the involvement of the operating system. Therefore, it has the advantages of low latency, high bandwidth, and reduced system resource consumption. From the perspective of system software design, RDMA can be directly regarded as a faster network. The current implementations of RDMA mainly include InfiniBand, RoCE (RDMA over Converged Ethernet) and iWARP (Internet Wide Area RDMA Protocol). Among them, RoCE can achieve high-performance data transmission on Ethernet by encapsulating RDMA operations in the Ethernet protocol and is the most widely used.

[0052] The Data Processing Unit (DPU) is a new generation of computing chip that is data-centric, I / O intensive, and uses software-defined technology to support infrastructure resource layer virtualization. It has the capabilities of improving computing system efficiency, reducing the total cost of ownership of the overall system, improving data processing performance, and reducing performance losses of other computing chips.

[0053] Linux bonding: The Linux bonding driver provides a way to bundle multiple network interface devices into a single network interface setting for use in network load balancing and network redundancy.

[0054] A memory region (MR) is a continuous memory managed by RDMA. RDMA controls the access rights of the memory for remote access. Each memory has a set of lkey and rkey, which are two 32-bit numbers used to represent the memory region. lkey and rkey are required when sending and receiving data.

[0055] The RDMA doorbell mechanism (DB for short) is a technology used in RDMA communication. It directly communicates between user state and kernel state, thus avoiding the bottleneck of CPU participation and data copying commonly seen in traditional network communication. The core advantage of this mechanism is that it can significantly reduce the latency of data transmission and improve the efficiency of data transmission.

[0056] Multiple network cards are virtualized into one to achieve redundancy; multiple network cards appear as one card with the same IP address; the network configuration uses Bonding technology to provide redundancy at the network port hardware level to prevent single point failure of a single network port application.

[0057] For multiple physical network cards, one of the physical network cards will be set as the Master, and the other network cards are Slaves. The MAC address of the Bond network card is taken from the physical network card marked as the Master, and then this MAC address is copied to the other physical network cards.

[0058] The active-standby mode is commonly used in daily life. In this mode, only one slave device is activated. Only when the interface of the working slave device fails, the other slave device interface will be activated. When a failover occurs in the active-standby mode, one or more gratuitous ARPs will be sent on the newly activated slave device interface. Gratuitous ARPs will be sent on the master and slave device interfaces and all VLAN interfaces configured on the interface. At least one IP address needs to be configured on these interfaces. The gratuitous ARPs sent on the VLAN interface will be attached with the appropriate VLAN id, so this mode provides fault tolerance.

[0059] from Figure 1 It can be seen that the related technology cannot realize the switching between multiple network card devices and has limitations. Figure 2 A schematic diagram of a communication architecture for remote direct memory access provided by an embodiment of the present disclosure is shown.

[0060] Figure 3a 1 is a flow chart of a switching method of a network card device in bonding mode provided by an embodiment of the present disclosure, and the method can be executed by a network card device. Figure 3a As shown, the method provided in this embodiment includes the following steps:

[0061] S301. In response to a switching operation of a network card device in bonding mode, a switching operation message is generated, and the switching operation message is passed to a preset callback interface; wherein the switching operation message is used to indicate switching a first network card device to a second network card device; the first network card device and the second network card device are network card devices in bonding mode.

[0062] In one example, the network card device based on the bonding mode includes a first network card device and a second network card device. The first network card device and the second network card device have the same hardware structure and the same resource ID. For details, see Figure 3b A schematic diagram of resource ID management is shown. The advantage of such a setting is that after the network card device is switched, it can be ensured that the network card device after the switch can use the index information of the network card device before the switch.

[0063] In one example, the first network card device represents the network card device before switching, and the second network card device represents the network card device after switching. Specifically, the switching operation can be triggered by a port exception in the first network card device. Further, the switching operation message can be a preset instruction message, a preset code file, or a preset identifier. The preset callback interface can be accessed in real time by the remote direct memory access driver module.

[0064] S302: Retrieve a switching operation message from a preset callback interface based on the remote direct memory access driver module.

[0065] In one example, after the remote direct memory access driver module finds that the switching operation message exists in the preset callback interface, it retrieves the switching operation message from the preset callback interface.

[0066] S303. Based on the remote direct memory access driver module, according to the switching operation message, the current data information of the first network card device is switched to the second network card device via the shared memory, and the current data information is executed in the second network card device; wherein the first network card device and the second network card device have the same hardware structure; and the shared memory is pre-created by the remote direct memory access driver module.

[0067] In one example, the shared memory can be accessed by the first network card device and can also be accessed by the second network card device. The current data information is the data information being processed by the first network card device. After obtaining the switching operation message, the remote direct memory access driver module first stores the current data information of the first network card device in the shared memory, then switches the first network card device to the second network card device, and then the second network card device executes the current data information.

[0068] The disclosed embodiment provides a switching method for a network card device in bonding mode, the method comprising: generating a switching operation message in response to a switching operation of the network card device in bonding mode, and transmitting the switching operation message to a preset callback interface; wherein the switching operation message is used to indicate that the first network card device is switched to the second network card device; the first network card device and the second network card device are network card devices in bonding mode; calling the switching operation message from the preset callback interface based on the remote direct memory access driver module; switching the current data information of the first network card device to the second network card device via the shared memory based on the remote direct memory access driver module according to the switching operation message, and executing the current data information in the second network card device; wherein the first network card device and the second network card device have the same hardware structure; and the shared memory is pre-created by the remote direct memory access driver module. By adopting this technical solution, when a network card device has only one port, it can also communicate with other devices in a remote direct memory access manner, thereby improving the stability of data transmission.

[0069] Figure 4a The flowchart of a method for switching a network card device in bonding mode provided by an embodiment of the present disclosure is shown. The embodiment of the present disclosure is optimized based on the above embodiment, and the embodiment of the present disclosure can be combined with various optional solutions in one or more of the above embodiments.

[0070] like Figure 4a As shown, the switching method of the network card device based on the bonding mode may include the following steps:

[0071] S401. In response to a switching operation of a network card device in bonding mode, a switching operation message is generated, and the switching operation message is passed to a preset callback interface; wherein the switching operation message is used to indicate switching a first network card device to a second network card device; the first network card device and the second network card device are network card devices in bonding mode.

[0072] In an example, this step may refer to the description of step S301.

[0073] S402: Retrieve a switching operation message from a preset callback interface based on the remote direct memory access driver module.

[0074] In an example, this step may refer to the description of step S302.

[0075] S403: Send a switching operation message to the first network card device and the second network card device based on the remote direct memory access driver module.

[0076] In one example, after receiving the switching operation message, the remote direct memory access driver module sends the switching operation message to the first network card device and the second network card device, thereby causing the first network card device to perform the corresponding operation and the second network card device to also perform the corresponding operation.

[0077] S404: After receiving the switching operation message, the first network card device suspends processing of current data information.

[0078] In one example, after receiving the switching operation message, the first network card device no longer processes the current data information and prepares for switching to the second network card device.

[0079] S405: The first network card device stores the current data information in the shared memory according to the switching operation message, and changes the state identifier of the shared memory from the first identifier to the second identifier after the transmission is completed.

[0080] In one example, the first network card device suspends processing of current data information and stores the current data information in a shared memory, and then after completing the storage of all current data information, modifies the state flag of the shared memory from a first flag to a second flag, wherein the second flag indicates that the shared memory completes the storage operation of all current data information.

[0081] S406: When the second network card device detects that the state identifier of the shared memory is the second identifier, it obtains current data information from the shared memory and switches the first network card device to the second network card device.

[0082] In one example, when the second network card device detects that the state identifier of the shared memory is the second identifier, it means that the second network card device knows that the shared memory has completed the storage operation of all current data information. Then the current data information is obtained from the shared memory, and the first network card device is switched to the second network card device.

[0083] In one example, the current data information includes sq information, rq information, cq information, etc.

[0084] In one example, the first network card device and the second network card device can access the MR memory and the shared memory. For a clearer description, see Figure 4b A schematic diagram of a memory structure is shown in FIG. Figure 4b It can be seen that both the first network card device and the second network card device can access MR memory, sq information, rq information, cq information, etc.

[0085] S407: Send a notification message to the remote direct memory access driver module based on the second network card device; wherein the notification message is used to indicate that the switching from the first network card device to the second network card device is completed.

[0086] In an example, the second network card device sends a notification message to the remote direct memory access driver module to notify the remote direct memory access driver module that the switching from the first network card device to the second network card device is completed.

[0087] S408, executing the current data information in the second network card device; wherein the first network card device and the second network card device have the same hardware structure; and the shared memory is pre-created by the remote direct memory access driver module.

[0088] In one example, the method further includes:

[0089] A shared memory is created based on the remote direct memory access driver module, and the shared memory state identifier is determined as the first identifier.

[0090] In an example, the shared memory is a physical address, and the first identifier indicates that the shared memory can be used.

[0091] The disclosed embodiment provides a switching method for a network card device in a bonding mode, the method comprising: the first network card device stores the current data information in a shared memory according to a switching operation message, and changes the state identifier of the shared memory from the first identifier to the second identifier after the transmission is completed. When the second network card device detects that the state identifier of the shared memory is the second identifier, it obtains the current data information from the shared memory and switches the first network card device to the second network card device. By adopting this technical solution, the network card device can be switched in time through the identifier of the shared memory, and the data import and export can be completed autonomously within the hardware, the driver is not aware of it, and the switching is smoother.

[0092] Figure 5 1 is a schematic diagram of a switching device based on a network card device in bonding mode provided by an embodiment of the present disclosure. The switching device based on a network card device in bonding mode can be understood as the network card device based on bonding mode or some functional modules in the network card device based on bonding mode. Figure 5 As shown, the switching device 50 based on the network card device in bonding mode includes:

[0093] The bonding module 501 is used to generate a switching operation message in response to a switching operation of a network card device in a bonding mode, and transmit the switching operation message to a preset callback interface; wherein the switching operation message is used to indicate that the first network card device is switched to the second network card device; the first network card device and the second network card device are network card devices in a bonding mode;

[0094] A remote direct memory access driver module 502 is used to retrieve a switching operation message from a preset callback interface;

[0095] The remote direct memory access driver module 502 is used to switch the current data information of the first network card device to the second network card device via the shared memory according to the switching operation message, and execute the current data information in the second network card device; wherein the first network card device and the second network card device have the same hardware structure; the shared memory is pre-created by the remote direct memory access driver module.

[0097] The first network card device 503 is used to store the current data information in the shared memory according to the switching operation message, and change the state identifier of the shared memory from the first identifier to the second identifier after the transmission is completed;

[0098] The second network card device 504 is used to obtain current data information from the shared memory and switch the first network card device to the second network card device when detecting that the state identifier of the shared memory is the second identifier.

In the RAM 1003, various programs and data required for the operation of the network card device 1000 based on the bonding mode are also stored. The processing device 1001, the ROM 1002 and the RAM 1003 are connected to each other through a bus 1004. An input / output (I / O) interface 1005 is also connected to the bus 1004.

[0109] Typically, the following devices may be connected to the I / O interface 1005: input devices 1006 including, for example, a touch screen, a touch pad, a keyboard, a mouse, a camera, a microphone, an accelerometer, a gyroscope, etc.; output devices 1007 including, for example, a liquid crystal display (LCD), a speaker, a vibrator, etc.; storage devices 1008 including, for example, a magnetic tape, a hard disk, etc.; and communication devices 1009.
