Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the protection scope of the present disclosure.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in an "or" relationship.

[0063] In recent years, with the development of virtualization technology in public clouds and the rise of SDN technology, higher requirements are put forward for the protocol stack of end systems, and traditional high-performance network cards have been difficult to meet these requirements. Therefore, intelligent network card technology has begun to enter the public's field of vision. Intelligent network cards use custom chips, high-speed network interfaces, and powerful software support to provide faster, safer, and more reliable network connections and data transmission services for data centers and enterprise networks.

[0064] Intelligent network cards have the following advantages:

[0065] I. Improve network performance: Intelligent network cards can achieve ultra-high data processing speed, throughput, and flow control efficiency by using dedicated chips and high-speed network interfaces, thereby improving network performance and response speed.

[0066] II. Safe and reliable: Intelligent network cards not only accelerate data transmission, but also provide better security features and protection mechanisms, such as data encryption, access control, firewalls, etc., thereby enhancing the security and stability of the network.

[0067] III. Support distributed storage and computing: Intelligent network cards can be combined with distributed storage, computing, and other technologies to achieve more efficient data processing and analysis, while also reducing network latency and load pressure, thereby improving overall performance and efficiency.

[0068] Four, offloading network functions: SmartNICs are equipped with computing capabilities, allowing them to offload all network functions, security functions, and storage functions from host servers, freeing up valuable processing power. For example, functions such as routing, network address translation, telemetry, load balancing, firewalling, etc. can be handled by SmartNICs, reducing the burden on host server CPUs.

[0069] Five, virtualization, load balancing, and data path optimization: SmartNICs can perform functions such as virtualization, load balancing, and data path optimization, making the network more flexible and efficient.

[0070] Six, flexibility and programmability: SmartNICs allow users to update or upgrade their firmware, flexibly add / modify the functions they provide, and allow security upgrades when needed. This makes network configuration and management more flexible and convenient

[0071] Most traditional servers are single nodes or multi-node servers composed of multiple single nodes, each node has its own CPU, memory, and NIC hardware resources, and nodes are relatively independent. The traditional NIC testing method is generally through two servers, each server is equipped with a SmartNIC to be tested, connected to a switch for packet testing, performance testing, etc. However, it cannot provide a complete virtualization testing scheme, and it is difficult to adapt to the testing needs of SmartNICs, and there are technical limitations.

[0072] To solve the above technical problems, the present disclosure provides a NIC testing method, which can provide a complete virtualization testing scheme for SmartNICs and can well adapt to the characteristics of SmartNICs.

[0073] Figure 1 is a step schematic diagram of a NIC testing method according to an embodiment of the present disclosure. As shown in Figure 1 the NIC testing system includes a virtual platform and a hardware layer, the hardware layer includes a dual-node server, the dual-node server is installed with a dual-port SmartNIC, and the virtual platform is deployed with different image containers.

[0074] The NIC testing system is a platform integrating multiple testing resources and technologies, which can support virtualization testing, such as image containers, etc. The virtual platform is a component in the NIC testing system, which uses virtualization technology to create and manage multiple isolated testing environments. Each environment corresponds to a different image container, and the container image contains the application programs, libraries, and configurations required for testing. By deploying different image containers to simulate different testing environments, the effect of testing environment isolation is achieved.

[0075] The dual-node server comprises two server nodes, each of which is independent of each other and can independently perform network card testing by using a dual-port intelligent network card, and can provide a redundant configuration to prevent a single point of failure.

[0076] The network card testing method can specifically comprise the following steps:

[0077] Step S11: In response to a network card testing request, a target image container is determined from the virtual platform; the target image container represents an independent testing environment.

[0078] In the case of initiating a testing request for a dual-port intelligent network card, the network card testing system receives the network card testing request. The network card testing request is analyzed to obtain specific parameters of the testing, and the testing scenario and testing target are determined; the network card testing system selects one or more appropriate image containers from the virtual platform, and uses these image containers as target image containers for testing the current dual-port intelligent network card. Any target image container corresponds to a testing environment and testing tools required for testing.

[0079] The target image container is loaded and started, and an independent testing environment is created in the virtual platform.

[0080] Each image container can be managed by a virtual machine, which can be a KVM virtual machine or a Vmware virtual machine.

[0081] Figure 2 is a KVM virtual machine diagram shown by an embodiment of the present disclosure. According to Figure 2 , it is a user interface of a virtual machine manager. Through this interface, a user can manage and monitor multiple virtual machine instances. The left side of the interface is a menu bar, which contains standard menu options such as "File", "Edit", "View", "Help", etc., for performing file management, editing settings, view switching, and obtaining help, etc. On the right side of the interface, multiple virtual machine instances and their current states are listed, including virtual machines including "Virtual Machine 1", "Virtual Machine 2", and "Virtual Machine 3".

[0082] Figure 3 is a Vmware virtual machine diagram shown by an embodiment of the present disclosure. According to Figure 3 , it is a page for adding a host to a Vmware virtual machine. A host can be added to a Vmware virtual machine, and multiple properties can be configured, such as: name and location, connection settings, host summary, license allocation, lock mode, resource pool, etc.

[0083] Step S12: Determine a network card testing model according to the target image container.

[0084] After determining the target image container, the target image container respectively and independently tests the dual-port intelligent network card. The test environment corresponding to each target image container is determined. According to the characteristics and test requirements of the target image container, the network card test model corresponding to each target image container is determined.

[0085] Step S13: According to the network card test model, the dual-port intelligent network card is tested by virtualization, and test data is obtained.

[0086] The network card test model includes various test parameters for testing the intelligent network card, such as specific network traffic patterns, load conditions, or other test parameters. According to the test parameters corresponding to the network card test model, the dual-port intelligent network card is tested by virtualization. During the virtualization test process, the network card test system simulates various network scenarios and load conditions to observe the performance of the dual-port intelligent network card under different conditions and collect relevant performance indicators and stability data.

[0087] During the virtualization test process, the test process is monitored, and test data including performance indicators, error logs, etc. are recorded.

[0088] Step S14: The test data is processed by the hardware layer to obtain a processing result.

[0089] During the comprehensive virtualization test of the intelligent network card, the test content of the virtualization test can include throughput test, delay test, packet loss rate test, protocol compatibility test, etc. The transmission, reception and processing of network traffic corresponding to these test contents are actually performed on the hardware layer. The throughput test is used to measure the amount of data that the network card can process per unit time, i.e. the data transmission speed. The delay test is used to evaluate the time required for a data packet to be sent and received, reflecting the processing speed of the network card and network delay. The packet loss rate test is used to test the proportion of data packets lost by the network card under certain conditions, reflecting the stability and reliability of the network. The protocol compatibility test is used to verify whether the network card supports and correctly processes various network protocols, ensuring its compatibility with different systems and devices. The test parameters corresponding to the test content can be used as test data.

[0090] During the virtualization test process, the virtual platform serves as the test control and management center, and generates various test data according to the defined network card test model. The test data interacts with the hardware layer through virtualization technology, and the hardware layer captures each test data and processes it according to the test requirements of the test data, such as forwarding, analysis, storage, etc., and generates a processing result.

[0091] Step S15: The processing result is transmitted to the virtual platform through the virtual network card interface corresponding to the dual-port intelligent network card on the dual-node server.

[0092] The processing results are transmitted back to the virtual platform. The virtual platform comprehensively evaluates the performance of the intelligent network card according to the results, in combination with preset performance indicators and evaluation criteria.

[0093] By using the embodiments of the present disclosure, the dependence on physical resources is reduced through the virtualized test environment, and the test efficiency is improved. The diversified image containers and test models provide rich test scenarios and configurations, enhancing the comprehensiveness of the test. The accurate test models and comprehensive test scenarios ensure the accuracy and reliability of the test. Through the image container, the test environment can be quickly and flexibly deployed and built, improving the test efficiency and repeatability. The close cooperation between the hardware layer and the virtual platform can significantly improve the test efficiency. The virtualization layer can quickly deploy the test environment, while the hardware layer provides stable physical resource support, ensuring the smooth progress of the test. The hardware layer directly processes the test data of the intelligent network card, ensuring the accuracy and real-time performance of the data.

[0094] In an optional embodiment, the virtual platform includes a virtual switch; the virtual switch includes test software and a plurality of virtual network cards; the determining of the network card test model according to the target image container includes: the target image container running a test tool provided by the test software; the test software determining a network card test model according to the test tool, and determining a target virtual network card according to the test tool; the virtual network card is used to simulate a corresponding network environment; the virtualization test of the dual-port intelligent network card according to the network card test model includes: according to the target virtual network card and the virtual switch, the test software performs a virtualization test on the dual-port intelligent network card based on the network card test model.

[0095] The virtual switch can forward data packets between image containers and between virtual machines and physical networks. The virtual switch allows network traffic to flow effectively between different virtualization and physical network components, while providing necessary isolation and security. Figure 4 is a schematic diagram of a virtual switch according to an embodiment of the present disclosure. As shown in Figure 4 , the virtual switch can be configured through a Vmware virtual machine. The network connection settings of the virtual switch can be configured.

[0096] The test software can be DPDK (Data Plane Development Kit). DPDK is an open-source library and driver collection for accelerating user-space packet processing, which is used for network performance testing and benchmarking. The test software is used to measure the performance of data transmission between the virtual network card and the virtual switch.

[0097] A virtual network card is a simulation of a network interface card in a virtual environment, allowing a virtual machine or container to communicate with a physical network or other virtual network elements.

[0098] Figure 5 is a schematic diagram of a virtual platform according to an embodiment of the present disclosure. As shown in Figure 5 there are multiple image containers, including image container 1, image container 2, image container 3, and image container 4, and there are virtual network cards corresponding to the image containers; each image container includes a data forwarding layer for external data transmission; the virtual network cards are configured into a virtual switch, including virtual network card 1, virtual network card 2, virtual network card 3, and virtual network card 4, and the virtual switch also includes test software that determines a corresponding network card test model according to network card test parameters corresponding to each image container. The virtual network cards interact with the test software and the image containers respectively.

[0099] A virtual switch is configured in the virtual platform, and the virtual switch is used for data packet forwarding and processing. By communication among the various image containers, the virtual switch, and the virtual network cards, a real network environment is simulated.

[0100] The target image container responds to the received network card test request, determines the network card test parameters according to the network card test environment corresponding to the target image container, and determines the network card test parameters as the running parameters of the test tool; according to the running of the test tool, the test software determines the corresponding network card test model. The running parameters of the test tool can determine the target virtual network card participating in the network card test. Different virtual network cards correspond to different network test environments.

[0101] The network card test parameters can be pre-set or configured by a user through a command line when virtualizing testing of a dual-port intelligent network card.

[0102] In a specific embodiment, when the test software is DPDK and the test tool is testpmd, the following are two examples of using DPDK testpmd applications to define network card test models:

[0103] #. / testpmd-l 48-64-w 0000:9e:00.0----burst=128--nb-cores=8--txd=4096

[0104] --rxd=512--txq=64--rxq=64--forward-mode=io--disable-hw-vlan-filter--stats-period=1

[0105] #. / testpmd-l 0-48-w 0000:20:00.0----burst=64--nb-cores=8--txd=4096

[0106] --rxd=1024--txq=64--rxq=64--forward-mode=txonly--disable-hw-vlan-filter--txpkts 1400--stats-period=1

[0107] `-l`: Specifies which CPU cores the DPDK application will run on. For example: `-l 48-64`: Specifies the range of logical CPU cores from 48 to 64; `-l 0-48`: Specifies the range of logical CPU cores from 0 to 48.

[0108] `-w`: Specifies the test device. `-w 0000:9e:00.0`: Specifies the PCI address of the network interface card to be initialized and configured; `-w 0000:20:00.0`: Specifies the PCI address of the network interface card to be initialized and configured.

[0109] `-n` or `--numa`: Specifies which NUMA node the application runs on. For example, `-n 1` binds the application to NUMA node 1.

[0110] `-m` or `--socket-mem`: Specifies the memory allocation for each NUMA node. For example, `-m1024,1024` means that each NUMA node is allocated 1024MB of memory.

[0111] `-i` or `--interactive`: Enables interactive mode, allowing commands to be entered at runtime.

[0112] `--nb-cores`: Specifies the number of cores to use, limiting the actual number of cores used for forwarding.

[0113] `--txd` and `--rxd`: specify the number of send and receive queues for each port, respectively.

[0114] `--burst`: Specifies the burst size of the data packets to be sent.

[0115] `--rxdpkt`: Specifies the number of buffers for each receive queue.

[0116] After determining the network interface card (NIC) test model, the test software performs virtualization testing on the dual-port smart NIC, executing the data transmission required for the virtualization test.

[0117] With the embodiments of the present disclosure, the required test environment, including virtual switches, virtual network cards, etc., can be quickly configured and deployed through the virtual platform, without waiting for or configuring physical hardware, and multiple network environments can be simulated on the same physical hardware, improving the utilization of hardware resources. Each virtual network card can simulate an independent network environment, ensuring the independence and isolation of the test process and avoiding mutual interference between different tests. The test tools provided by the test software can automatically execute the test process, reducing the complexity and error rate of manual operation. Various parameters in the test process can be configured and adjusted as needed, enhancing the controllability of the test.

[0118] In an optional embodiment, the mirror container is configured by the following steps, including: installing container software and test software; performing a compilation operation through the test software to obtain test tools; the test tools include various test parameters; performing a mapping operation through the container software to obtain various mirror containers; the mapping operation includes: mapping device directories, mapping memories, mapping node information, and mapping device files; copying the test tools into the mirror containers; configuring each network card test parameter in the test tools according to the network card test environment corresponding to the mirror container to obtain a test script corresponding to the mirror container.

[0119] Run the container software installation command to install the container software. After executing the installation command, the container detection command can be run to determine whether the installation is successful.

[0120] For example, if the container software adopted by the present disclosure is a Docker container. Then execute the following command to install the container software:

[0121] # yum install-y docker-ce docker-ce-cli containerd.io –allowerasing Install container software

[0122] The following command can be executed to check whether the Docker container is installed:

[0123] # docker info command to check whether the installation is successful

[0124] Run the installation command of the test software to install the test software. Select the compilation platform of the test software. After the compilation platform is selected, the test software is compiled.

[0125] After the test software is compiled, a test tool is obtained, and the test tool includes various test parameters. In the case of testing a network card, various test parameters in the test tool need to be configured. For example, when the test software is DPDK, the test tool is testpmd obtained by compilation.

[0126] After the container software is installed, various container instances, that is, image containers in the present disclosure, need to be created by the container software. First, an image file is pulled, and the image file can be centos.

[0127] After the image file is pulled, a mapping operation is performed by the container software to obtain an image container. The mapping operation enables the container to access resources in the host or network while maintaining the isolation of the resources and avoiding resource conflicts. The following is a specific command for creating an image container:

[0128] docker run-dit--privileged\

[0129] -v / sys / bus / pci / devices: / sys / bus / pci / devices\

[0130] -v / sys / kernel / mm / hugepages: / sys / kernel / mm / hugepages\

[0131] -v / sys / devices / system / node: / sys / devices / system / node\

[0132] -v / dev: / dev--name centos2 5d0da3dc9764 / usr / sbin / init

[0133] Among them, -dit: create a container, connect a terminal, and run in the background; --privileged: increase system permissions; -v / sys / bus / pci / devices: / sys / bus / pci / devices: pass SR-IOV virtual machine network cards to the container; -v / sys / kernel / mm / hugepages: / sys / kernel / mm / hugepages: mount large page memory to the container; -v / sys / devices / system / node: / sys / devices / system / node: mount numa node information to the container; -v / dev: / dev: mount the igb_uio driver to the container.

[0134] The test tool obtained by installing the test software is copied to each image container, so that the image container can use the test tool, and a corresponding network card test model is generated by the test software to perform virtualization testing on the dual-port intelligent network card.

[0135] The test tool includes various network card test parameters, which can be configured to develop personalized dual-port intelligent network card testing strategies. The various network card test parameters can be configured in advance according to the network card test environment corresponding to the image container, to obtain a test script corresponding to the image container, and to enable the image container to access the corresponding test script. When any image container runs the test software, the various test parameters are obtained from the test script, without the need to configure various network card test parameters during testing. The network card test parameters can include: test target, hardware resources, test environment, etc.

[0136] According to the embodiments of the present disclosure, the container software and the test software are automatically installed, reducing the complexity and error rate of manual deployment. Multiple image containers can be quickly created, each of which can independently run tests, thereby executing multiple test scenarios in parallel, significantly improving test efficiency. The test parameters are dynamically configured according to the network card test environment corresponding to the image container, enabling the test to accurately simulate the application behavior under actual network conditions, improving the accuracy and effectiveness of the test. The container technology allows efficient use of system resources, and reduces resource consumption and waste through a lightweight container isolation mechanism.

[0137] In an optional embodiment, the method further comprises: obtaining a virtualization test result according to the processing result; and transmitting the test result to an image container different from the target image container.

[0138] At the hardware layer, data transmission required for a series of dual-port intelligent network card performance tests is performed according to test data, such as throughput, delay, packet loss rate, etc. After the test is completed, the hardware layer packages the test result data and prepares to transmit it to the virtual platform.

[0139] A stable data transmission channel is established between the virtual platform and the hardware layer to ensure that the test result data can be transmitted safely and quickly. The virtual platform receives the test result data packet from the hardware layer and performs preliminary data verification to ensure the integrity and correctness of the data.

[0140] The virtual platform analyzes the received test result data and extracts key performance indicators such as throughput and delay. According to a preset evaluation standard or algorithm, the performance of the dual-port intelligent network card is comprehensively evaluated to obtain a virtualization test result. The virtualization test result can be converted into a specific data format or protocol for subsequent processing and transmission.

[0141] The virtual platform identifies another image container different from the target image container as the receiver of the virtualization test result. The virtualization test result is transmitted to the designated image container through the inter-container communication mechanism. In the receiving image container, the virtualization test result is further processed or displayed, such as generating a test report, triggering an alarm, etc.

[0142] For example, the processing result can be the number of data packets processed per second (PPS, Packets Per Second) and the test packet length of the receiving end. The receiving bandwidth of the current network can be calculated according to the number of data packets processed per second and the test packet length, so as to determine the performance of the dual-port intelligent network card in the network card test environment corresponding to the target image container. The following calculation formula can be used to calculate the bandwidth:

[0143] PPS x packet length x 8bit / B x 10-9 = bandwidth

[0144] The test packet length can be 1400B. According to the test data, the current bandwidth can be obtained as:

[0145] 16036490 pps x 1400B x 8bit / B x 10-9 ≈ 179Gbp

[0146] By using the embodiments of the present disclosure, the test period is greatly shortened and the test efficiency is improved through automatic testing and data transmission. The accuracy and reliability of the test results are ensured by using professional test tools and stable data transmission channels. The test results are arranged into structured reports and transmitted to designated image containers, which facilitates subsequent analysis and utilization. Based on the virtualization test results, the performance of the dual-port intelligent network card can be optimized and improved to enhance its performance in actual applications.

[0147] Figure 6 is a hardware layer configuration schematic diagram shown by an embodiment of the present disclosure. As shown in Figure 6 the hardware layer further includes a switch; the server nodes of the dual-node server integrate the virtual network card interfaces corresponding to the network card interfaces of the dual-port intelligent network card; and the switch ports of the switch are dynamically linked to the network card interfaces.

[0148] The dual-port intelligent network card installed on the dual-node server can be a Multi Host intelligent network card. The Multi Host intelligent network card can virtually obtain multiple virtual network card interfaces under the computer system from actual network card interfaces. The virtual network card interfaces are configured to the corresponding nodes of the dual-node server. Dynamic link aggregation is performed on the network card interfaces of the dual-node server and the switch ports of the switch, so that the switch ports of the switch and the network card interfaces are dynamically aggregated. The bandwidth can be stacked and the link can be redundant, thereby improving the efficiency and reliability of data transmission.

[0149] As shown in Figure 6 The virtual network card interfaces of the dual-port intelligent network card are configured on the server nodes, for example, the virtual network card interface 0 and the virtual network card interface 1 are configured on the server node 0, and the virtual network card interface 0 and the virtual network card interface 1 are configured on the server node 1. The switch includes two switch binding ports, and each switch binding port includes multiple switch ports, which are physical ports on the switch. The switch and the dual-node server perform data interaction through the virtual network card interfaces on the server side and the switch binding ports on the switch side.

[0150] In an optional embodiment, the server nodes of the dual-node server integrate the virtual network card interfaces corresponding to the network card interfaces of the dual-port intelligent network card, including: performing virtual operation on the network card interfaces of the dual-port intelligent network card to obtain virtual network card interfaces; the number of virtual network card interfaces corresponding to any network card interface is equal to the number of nodes corresponding to the server; the virtual network card interfaces corresponding to the same network card interface are respectively corresponding to different nodes of the server, so that the server nodes of the dual-node server integrate one virtual network card interface corresponding to each network card interface.

[0151] The two network card interfaces of the dual-port intelligent network card are respectively configured to the server nodes of the dual-node server, and one server node is configured with one network card interface. The network card interface is the actual interface of the dual-port intelligent network card.

[0152] The number of server nodes on the dual-node server is determined. According to the number of server nodes, the network card interfaces on the dual-port intelligent network card are virtually operated. After virtually operating on any network card interface, a virtual network card interface corresponding to the network card interface is obtained. It is required that the number of virtual network card interfaces corresponding to any network card interface is the same as the number of server nodes.

[0153] The virtual network card interfaces corresponding to the same network card interface are respectively deployed on different server nodes. Each server node is configured with a complete set of virtual network card interfaces, and the complete set of virtual network card interfaces means that each server node is configured with a virtual network card interface corresponding to each network card interface.

[0154] By virtualizing the network card interfaces of the intelligent network card according to the number of server nodes, it can be ensured that each node can obtain necessary network resources. The virtual network card interfaces can be easily configured and managed, and the number of network interfaces can be expanded as needed to meet the needs of high concurrency and large data transmission. The virtual network card interfaces on each node are independent, which helps to realize the security isolation of data. By respectively deploying the virtual network card interfaces corresponding to the same network card interface on different server nodes, load balancing and redundant backup of network traffic can be realized.

[0155] In an optional embodiment, the switch ports of the switch are dynamically linked and aggregated with the network card interfaces, including: on the server side, creating a first binding interface and naming the first binding interface; adding each network card interface of the dual-port intelligent network card corresponding to the dual-node server to the first binding interface; on the switch side, creating each second binding interface and naming the second binding interface; adding each switch port to the second binding interface; the second binding interface includes at least two switch ports; determining the second binding interface as a switch binding port; adding each switch binding port to the bridge domain; the bridge domain allows each switch binding port to communicate within the same network hierarchy.

[0156] The dynamic link aggregation operation on each network card interface on the dual-node server and the switch port on the switch needs to be configured respectively from the server side and the switch side, so as to realize the dynamic link aggregation of the switch ports of the switch with the network card interfaces. Dynamic link aggregation can realize the functions of improving network bandwidth, reducing delay, enhancing the reliability and stability of data transmission, etc.

[0157] On the server side, a virtual interface for binding, that is, a first binding interface, needs to be created, and the first binding interface serves as an aggregation point for multiple network card interfaces. The first binding interface is named for easy management and maintenance. The multiple network card interfaces of the dual-port intelligent network card in the dual-node server are logically added to the previously created binding interface.

[0158] Switch ports are physical interfaces on a switch. At the switch end, multiple virtual interfaces for bonding, i.e. second bonding interfaces, are created, and the switch ports on the switch are respectively added to the corresponding second bonding interfaces, and each second bonding interface includes at least two switch ports. Each second bonding interface is respectively named, and the names of the second bonding interfaces are different from each other, so as to facilitate management.

[0159] After the addition of the switch ports is completed, it is confirmed that the switch ports have been correctly aggregated into a logical bonding port, i.e. a second bonding interface, and the second bonding interface is determined as a switch bonding port. Each switch bonding port is added to a bridge domain; the bridge domain is used to allow each switch bonding port to communicate in the same network layer.

[0160] In one scenario, the dynamic link aggregation of the switch ports of the switch and the network card interfaces can be performed through the following code:

[0161] Server end:

[0162] A first bonding interface is created, and the name of the first bonding interface is bond30

[0163] # nmcli con add type bond ifname bond30 bond.options "mode=4,miimon=100,lacp_rate=fast,xmit_hash_policy=layer3+4"

[0164] Two network card interfaces are added under bond30:

[0165] # nmcli connection add type ethernet ifname ens30f0np0 master bond30

[0166] # nmcli connection add type ethernet ifname ens30f1np1 master bond30

[0167] Switch end:

[0168] The settings of the switch ports are deleted:

[0169] # nv unset interface swp1-32

[0170] Swp1 swp3 is configured as a bonding mode and is added to a switch bonding port

[0171] #nv set interface bond1 bond member swp1 swp3

[0172] Add each switch binding port to the same bridge domain

[0173] #nv set interface bond1-16 bridge domain br_default

[0174] Switch applies the above configuration and checks the configuration

[0175] #nv config apply

[0176] With the embodiments of the present disclosure, by performing dynamic link aggregation configuration on the server side and the switch side respectively, the performance of the entire network system can be significantly improved. As the business demand grows, more network card interfaces or switch ports can be easily added to the corresponding binding interfaces to meet higher network bandwidth and performance requirements. When the network fails, since the dynamic link aggregation technology is adopted, it is easier to locate the problem, and due to the existence of standby interfaces and redundant paths, the fault recovery process will also be more rapid and efficient.

[0177] In an optional embodiment, the hardware layer configured as above can be used to implement the following method for processing virtualization test on the hardware layer. The test data is processed through the hardware layer to obtain a processing result, including: the first switch binding port of the switch receives the test data and transmits the test data to each network card interface of the dual-port intelligent network card; the first virtual network card interface corresponding to the network card interface receives the test data and processes the test data through the dual-port intelligent network card to obtain a processing result; the processing result is transmitted to the virtual platform, including: the dual-port intelligent network card transmits the processing result to the second switch binding port of the switch through the second virtual network card interface located in the same server node as the first virtual network card interface; the second switch binding port transmits the processing result to the virtual platform; wherein, after performing dynamic link aggregation on the switch port, the first switch binding port and the second switch binding port are obtained.

[0178] On the basis of dynamic link aggregation of the switch port of the switch and the network card interface, after determining the test data generated by the virtualization test, a first switch binding port is determined from each switch binding port of the switch to receive the test data. The first switch binding port is any one of the switch binding ports of the switch.

[0179] After the first switch binding port receives the test data, the test data is transmitted to each network card interface through the first switch binding port via the aggregation link. The transmitting network card interface needs to be dynamically aggregated with the switch port of the switch. If there is a network card interface that is not dynamically aggregated with the switch port, the first switch binding port does not transmit the test data to the network card interface.

[0180] For any network card interface that receives the test data, the test data is transmitted to any virtual network card interface corresponding to the network card interface. The virtual network card interface is configured on a server node of the dual-node server, and the test data is processed by the dual-port intelligent network card on the server node. The server nodes of the dual-node server are independent of each other, and the receiving and sending of the same test data correspond to the same server node.

[0181] The dual-port intelligent network card obtains the test data through the first virtual network card interface and processes the test data to obtain a test result of the test data. The test data can be processed by using the built-in processor and the special hardware acceleration unit of the dual-port intelligent network card, such as performing data packet analysis, protocol processing, and flow control. The processing result can reflect the performance of the dual-port intelligent network card under specific test conditions.

[0182] The test result is sent to the switch through a second virtual network card interface on the same server node as the first virtual network card interface. The first virtual network card interface and the second virtual network card interface are respectively virtually obtained from different network card interfaces. For example, the first virtual network card interface is obtained from network card interface A, and the second virtual network card interface is obtained from network card interface B.

[0183] The second switch binding port different from the first switch binding port on the switch receives the processing result and transmits the processing result to the virtual platform.

[0184] By using the embodiments of the present disclosure, the dynamic link aggregation operation binds multiple physical links or ports into a logical link, which significantly improves the overall bandwidth. The dynamic link aggregation provides link redundancy function, so that even if part of the link fails, the remaining link can still maintain the continuity of data transmission, thereby improving the reliability of the network. After the dual-port intelligent network card processes the test data, the test result is fed back to the switch through different virtual network card interfaces, which realizes the closed-loop processing of the test data and helps to evaluate and optimize the network performance. The nodes of the dual-node server are independent of each other, and the receiving and sending of the same test data correspond to the same server node, which ensures the consistency and accuracy of data processing.

[0185] In an optional embodiment, different users or test teams can be allowed to run tests independently in the same network card test system without interfering with each other, while improving resource utilization. An independent virtual network environment and resource pool are created for each tenant in the virtual platform, including image containers, virtual switches, virtual network cards, etc. Resource allocation is automatically adjusted according to test requirements to improve test efficiency and resource utilization.

[0186] Figure 7 is a schematic diagram of the overall architecture of a network card test system according to an embodiment of the present disclosure. As shown in Figure 7 , it includes image containers, virtual switches, a resource control center, a switch, and a dual-node server. The image containers include image container 1, image container 2, image container 3, and image container 4. The virtual switch includes four interaction interfaces, including interaction interface 1, interaction interface 2, interaction interface 3, and interaction interface 4. Data transmission between the virtual switch and the image containers is achieved through the interaction interfaces. The switch includes two switch binding ports, switch binding port 1 and switch binding port 2. The dual-node server includes two server nodes, such as server node 0 and server node 1. Each server node includes two virtual network card interfaces, virtual network card interface 0 and virtual network card interface 1. The virtual network card interfaces 0 or 1 of the two server nodes correspond to the same network card interface.

Figure 7The illustrated network card test system performs virtualization testing on a dual-port intelligent network card. In the case where the mirror container 1 needs to perform virtualization testing on a dual-port intelligent network card, an interaction interface, for example, the interaction interface 1, is determined on the virtual switch, the network card test parameters corresponding to the mirror container 1 are transmitted to the virtual switch, the virtual switch determines a network card test model through the network card test parameters, and performs virtualization testing on the dual-port intelligent network card through the network card test model; the test data generated in the virtualization testing is determined; the test data is transmitted to any switch binding port, for example, the switch binding port 1, on the switch through the resource control center; the switch binding port 1 transmits the test data to each network card interface of the dual-port intelligent network card on the server again; the network card interface receives the test data through the corresponding virtual network card interface, for example, the virtual network card interface 0 on the server node 0 and the virtual network card interface 1 on the server node 1; after the virtual network card interface 0 on the server node 0 and the virtual network card interface 1 on the server node 1 receive the test data, the test data is processed to obtain a processing result; the processing result corresponding to the test data received by the virtual network card interface 0 on the server node 0 is transmitted to the switch binding port 2 through the network card test interface 1 on the server node 0; the processing result corresponding to the test data received by the virtual network card interface 1 on the server node 1 is transmitted to the switch binding port 2 through the network card test interface 0 on the server node 1; the switch binding port 2 transmits the test result to the virtual switch through the resource control center again, and the virtual switch obtains a virtualization testing result according to the processing result and transmits the virtualization testing result to any mirror container different from the mirror container 1, for example, the mirror container 3.
