[0059] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work are within the protection scope of the present application.

[0060] Figure 1 is a step flow chart of a test method of an intelligent network card provided by an embodiment of the present application, applied to a server, the server is deployed with an intelligent network card, and the intelligent network card is a network interface card that can process tasks by a system processor. The intelligent network card can complete combinations of encryption / decryption, firewall, TCP / IP, HTTP and any processing task by using the processor on the board.

[0061] As shown in Figure 1 , the method can include:

[0062] Step 101, dividing system resources of the server to obtain a plurality of system resource groups corresponding to a plurality of virtual network card ports; the plurality of system resource groups correspond to a plurality of resource limit thresholds, and the resource limit threshold corresponding to each system resource group is used to limit the resource usage of the system resources in each system resource group, the plurality of virtual network card ports are obtained based on virtualization of an intelligent network card in the server, and the plurality of system resource groups and the plurality of virtual network card ports correspond one by one.

[0063] In the embodiment of the present application, by setting the intelligent network card to be virtualized, a plurality of virtual network card ports (VF) can be obtained. For example, by enabling the single root I / O virtualization (SR-IOV) under the server basic input output system (BIOS) and the virtualization function of the network card, a plurality of virtual network card ports can be obtained based on the virtualization of the intelligent network card. The single root I / O virtualization interface is an extension of the peripheral component interconnect express (PCIE). The SR-IOV allows a device (such as a network card) to separate the access of its resources among various PCIe hardware functions. Based on a preset tool in the server, the system resources of the server are divided according to a preset division rule, so that the obtained system resource groups after division are one-to-one corresponding to the virtual network card ports. The preset division rule can be to allocate the system resources according to a preset ratio or a preset corresponding relationship to obtain a plurality of system resource groups. For example, based on the system resources corresponding to the plurality of virtual network card ports, the system resources of the server can be divided, that is, for any virtual network card port, the system resources corresponding to the virtual network card port can be divided into a system resource group, and the system resource group corresponds to the virtual network card port. It can be understood that the system resources corresponding to the virtual network card port refer to the system resources required by the processes running in the virtual terminal corresponding to the virtual network card port. Dividing the system resources corresponding to the virtual network card port into a system resource group means that the system resources required by the processes running in the virtual terminal corresponding to the virtual network card port are included in the same system resource group. Each system resource group corresponds to a resource limit threshold, which is used to limit the resource usage of the system resources in the system resource group. The system resource group corresponding to each virtual network card port corresponds to a resource limit threshold, that is, the system resources required by the processes running in the virtual terminal corresponding to each virtual network card port correspond to a resource limit threshold.

[0064] Among them, different system resource groups can correspond to different resource limit thresholds, or a plurality of system resource groups can correspond to the same resource limit threshold. It can be understood that the setting of the resource limit threshold can be set according to the test requirements, and the embodiment of the present application does not limit this. The system resources can include processor resources, memory resources, network resources, etc. The preset tool can be a tool for limiting, controlling and separating the resources of a process group, for example: the preset tool can be cgroup software, and accordingly, the system resource group can be a control group (cgroup).

[0065] In step 102, based on the preset test command, the traffic of the multiple virtual terminals corresponding to the multiple virtual network card ports is tested to obtain the test result corresponding to the intelligent network card.

[0066] In the embodiment of the present application, the preset test command can be used to instruct the server to run the network card test program to test the traffic of the multiple virtual terminals corresponding to the multiple virtual network card ports of the server. The test type can include performance test, stress test, packet loss rate test, etc. The network card test program can be deployed in the server. In response to the preset test command, the network card test program is run to test the traffic of the multiple virtual terminals corresponding to the multiple virtual network card ports based on the preset network card test script file. The network card test program can include network card performance test program, network card stress test program, etc. The corresponding network card test script file can include network card performance test script file, network card stress test script file, etc. Since the multiple virtual network card ports are obtained based on the virtualization of the intelligent network card, testing the traffic of the multiple virtual terminals corresponding to the multiple virtual network card ports can realize the test of the intelligent network card, and further obtain the test result corresponding to the intelligent network card. For example, in the case of performance test instructed by the preset test command, the corresponding parameters of the network card performance test script file are set according to actual needs, the test task is generated and the network card performance test script file is run to perform the network card performance test. Through the network automatic packet sending tool, different size data packets can be continuously sent to the multiple virtual terminals corresponding to the multiple virtual network card ports for testing. When the test is completed, the network card performance test parameters of the multiple virtual terminals corresponding to the intelligent network card are generated and saved. It can be understood that based on the network card performance test parameters of the multiple virtual terminals corresponding to all the virtual network card ports, the network card performance test result corresponding to the intelligent network card can be obtained.

[0067] In summary, in the embodiment of the present application, by dividing the system resources of the server, a plurality of system resource groups corresponding to a plurality of virtual network card ports are obtained; the plurality of system resource groups correspond to a plurality of resource limit thresholds, the resource limit threshold corresponding to each system resource group is used to limit the resource usage of the system resources in each system resource group, the plurality of virtual network card ports are obtained based on the virtualization of the intelligent network card in the server, and the plurality of system resource groups and the plurality of virtual network card ports correspond one by one; based on a preset test command, the traffic of a plurality of virtual terminals corresponding to the plurality of virtual network card ports is tested, and a test result corresponding to the intelligent network card is obtained. In this way, by dividing the system resources of the server, a plurality of system resource groups corresponding to a plurality of virtual network card ports are obtained, and in the case of testing the traffic of a plurality of virtual terminals corresponding to the plurality of virtual network card ports, the system resources corresponding to each virtual network card port are independent and do not interfere with each other. Further, the resource usage of the system resources of the system resource group corresponding to the virtual network card port reflects the resource load corresponding to the virtual network card port, that is, by limiting the resource usage of the system resources, the resource load corresponding to the virtual network card port can be reduced to a certain extent. In this way, by setting the resource limit threshold to limit the resource usage of the system resources of the system resource group, the system resource load corresponding to each virtual network card port can also be limited to a certain extent, and then a diversified test scene for testing different system resource loads can be constructed to meet diversified test requirements, and the comprehensiveness of the network card test is improved to a certain extent.

[0068] Further, in the case of testing a plurality of virtual terminals corresponding to a plurality of virtual network card ports, it is not necessary to deploy upper virtualization software such as kvm, xen, vmware and the like, and by dividing the system resources of the server and setting the resource limit threshold, a test environment can be quickly deployed, the test period is shortened to a certain extent, and the time spent for the network card test is reduced.

[0069] Optionally, the embodiment of the present application can further include the following steps:

[0070] Step 201, based on a target processing instruction, the intelligent network card is virtualized to obtain the plurality of virtual network card ports.

[0071] In the embodiment of the present application, the target processing instruction can be used to instruct the virtualization of the intelligent network card. In response to the target processing instruction, the intelligent network card is configured for virtualization through the intelligent network card driver to obtain a plurality of virtual network card ports. The intelligent network card driver is a driver corresponding to the intelligent network card, which is generally provided by the manufacturer of the intelligent network card and is not limited here. For example, the SR-IOV technology supported by the network card can be used to allow the intelligent network card to map the physical port to a plurality of virtual network card ports, so that each virtual network card port can be bound to a virtual machine, thereby saving processor resources and improving network latency and overall performance. It can be understood that the creation method of the virtual network card port is different for network cards produced by different manufacturers, and the number of virtual network card ports that can be created may also be different. The number of virtual network card ports can be set according to the test requirements in combination with the characteristics of the network card, for example, the number of virtual network card ports can be set to the maximum number of ports supported by the intelligent network card, such as 8.

[0072] Correspondingly, step 101 can include the following steps:

[0073] Step 202, for any virtual network card port in the plurality of virtual network card ports, the system resources used by the virtual terminal corresponding to the virtual network card port in the system resources of the server are divided into the same system resource group.

[0074] In the embodiment of the present application, in the case of obtaining a plurality of virtual network card ports, the processes running in the virtual terminal corresponding to each virtual network card port will occupy a part of the system resources in the server, therefore, the system resources used by the virtual terminal corresponding to the virtual network card port can be used as the basis for dividing the system resource group, that is, the system resource group contains the system resources used by the virtual terminal corresponding to the same virtual network card port, such as processor resources, memory resources, network resources, etc.

[0075] In the embodiment of the present application, by virtualizing the intelligent network card to obtain a plurality of virtual network card ports, and dividing the system resources used by the virtual terminal corresponding to the virtual network card port into the same system resource group, the system resources used by the virtual terminal corresponding to the virtual network card port can be isolated and split to a certain extent, which facilitates different resource load settings for the system resources used by the virtual terminal corresponding to different virtual network card ports, and further constructs different load test scenarios.

[0076] Optionally, the resource limit threshold includes a first threshold and a second threshold.

[0077] Step 202 can include the following steps:

[0078] Step 2021, create a control resource pool for the virtual network card port, and assign the processes in the virtual terminal corresponding to the virtual network card port to the control resource pool.

[0079] In the embodiment of the present application, for any virtual network card port in the plurality of virtual network card ports, a control resource pool is created for the virtual network card port. Resource pool is considered as a design pattern, and the resources here mainly refer to system resources, which are not exclusively owned by a process or internal resources. A client requests resources from the pool and uses the returned resources for specified operations. When the client finishes using the resources, the resources are put back into the pool instead of being released or discarded. Illustratively, the creation of the control resource pool can be achieved by the following steps: mkdir / sys / fs / cgroup / cpuset / disk_resources_cpu. Each virtual terminal corresponding to a virtual network card port runs a process, and the processes in the virtual terminal corresponding to the virtual network card port can be assigned to the control resource pool. The processes in the virtual terminal can include the processes currently running on the virtual terminal and the processes to be subsequently run on the virtual terminal. Illustratively, the assignment of the processes in the virtual terminal to the control resource pool can be achieved by the following steps: echo$$> / sys / fs / cgroup / cpuset / disk_resources_cpu / tasks.

[0080] Step 2022, set the first threshold and the second threshold for the control resource pool, and divide the system resources used by the processes assigned to the control resource pool into the same system resource group; the first threshold is used to limit the processor resources used by the processes, and the second threshold is used to limit the memory resources used by the processes.

[0081] In this embodiment of the invention, a first threshold is set for the control resource pool to limit the processor resource usage of processes in the virtual terminal corresponding to the virtual network interface card port within the control resource pool. The first threshold includes at least a threshold for limiting the amount of processor resources used, a threshold for limiting the number of processor cores used, and a threshold for limiting processor utilization. The first threshold is used to limit the amount of processor resources used, the number of processor cores, and the processor utilization of processes in the virtual terminal corresponding to the virtual network interface card port within the control resource pool. By setting the first threshold, the processor resource usage, such as the amount of processor resources used, the number of processor cores, and the processor utilization of processes in the virtual terminal corresponding to the virtual network interface card port within the control resource pool, can be controlled within the first threshold range. A second threshold is set for the control resource pool to limit the memory resource usage of processes in the virtual terminal corresponding to the virtual network interface card port within the control resource pool. The second threshold may include a threshold for limiting the amount of memory resources used. The second threshold is used to limit the amount of memory resources used by processes in the virtual terminal corresponding to the virtual network interface card port within the control resource pool. By setting the second threshold, the memory resource usage, such as the amount of memory resources used by processes in the virtual terminal corresponding to the virtual network interface card port within the control resource pool, can be controlled within the first threshold range.

[0082] Binding a control resource pool to a system resource group (cgroup) enables resource management. System resources used by processes allocated to the control resource pool are grouped into the same system resource group. These system resources can include processor resources, memory resources, and network resources used by processes in the virtual terminal corresponding to the virtual network interface port.

[0083] In this embodiment of the invention, by allocating the processes in the virtual terminal corresponding to the virtual network interface card port to the control resource pool, and setting a first threshold to limit the processor resources used by the processes and a second threshold to limit the memory resources used by the processes in the control resource pool, the resource quota used by the processes in the virtual terminal corresponding to the virtual network interface card port can be controlled, thus preventing a certain process from occupying too many system resources and balancing the occupation of system resources.

[0084] Optionally, the system resource group includes network resources used by processes running in the control resource pool.

[0085] Embodiments of the present invention may further include the following steps:

[0086] Step 301: Create a corresponding network namespace for the virtual network interface card (NIC) port; different virtual NIC ports correspond to different network namespaces, and different network namespaces are isolated from each other.

[0087] In this embodiment of the invention, a corresponding network namespace is created for each virtual network interface card (NIC) port. A network namespace (ns) is a code organization method used in many programming languages. Namespaces are used to categorize and distinguish different code functions, preventing conflicts caused by identical variable names when different code snippets (typically used by different people collaborating or calling existing code snippets) are used simultaneously. For each virtual NIC port, a corresponding network namespace is created. Different network namespaces are isolated from each other; that is, the network resources used by processes running in virtual terminals corresponding to different virtual NIC ports are isolated and do not interfere with each other.

[0088] Step 302: Allocate the network resources in the system resource group allocated to the virtual network card port to the network namespace.

[0089] In this embodiment of the invention, the network resources used by the processes running in the virtual terminal corresponding to the virtual network interface card (NIC) port in the system resource group are allocated to the network namespace created for that NIC port. Further, a target virtual interface corresponding to the NIC port can be created within the network namespace to assign the NIC port to the network namespace. For example, a blank virtual interface can be created within the network namespace and connected to the NIC port to be assigned (i.e., the NIC port corresponding to the network namespace), using this blank virtual interface as the target virtual interface. An Internet Protocol Address (IP address) is configured for the current network namespace, and a virtual LAN name is configured for the NIC port. After configuration, the NIC port is marked as assigned.

[0090] In this embodiment of the invention, by allocating network resources to network namespaces, each network namespace has its own independent network resources. Therefore, different processes running in different virtual terminals corresponding to different virtual network card ports do not interfere with each other's use of the same resource in their respective network namespaces, thus avoiding a process occupying too many network resources and affecting the test results of the network card.

[0091] Optionally, embodiments of the present invention may further include the following steps:

[0092] Step 401: Set the multiple virtual network interface card ports to the same network segment, and establish a communication connection between the multiple virtual network interface card ports based on the virtual switch in the server.

[0093] In this embodiment of the invention, a virtual switch (openvswitch, OVS) can be deployed in the server. The mapped ports of multiple virtual network interface cards (NICs) are added to the bridge of the virtual switch configured in the smart NIC. By setting the IP addresses of multiple virtual NICs in the same network segment, communication between the multiple virtual NICs can be ensured.

[0094] For example, allocating network resources used by processes running in a virtual terminal corresponding to a virtual network interface card port in a system resource group to the network namespace can be achieved through the following steps:

[0095] Taking virtual network interface cards (NICs) as vf1 and vf2 as examples, network namespace 1 (ns1) is created for vf1 and network namespace 2 (ns2) is created for vf2 respectively:

[0096] 1) Create a network namespace 1

[0097] 1. Create a netns application named ns1

[0098] #ip netns add ns1

[0099] 2. Start the loopback interface in the namespace.

[0100] #ip netns exec ns1 ip link set lo up

[0101] 2) Add vf1 to namespace 1

[0102] 1. Add virtual interface 1 to the created network namespace.

[0103] #ip link set eth1 netns ns1

[0104] 2. Enable namespace ns1

[0105] &&ip netns exec ns1 ip link set eth1 up

[0106] 3. Configure IP addresses for the current namespace.

[0107] ip netns exec ns1 ip addr add 1.1.1.10 / 24dev eth1

[0108] 3) Create a network namespace 2

[0109] 1. Create a netns application named ns2

[0110] #ip netns add ns2

[0111] 2. Start the loopback interface in the namespace.

[0112] #ip netns exec ns2 ip link set lo up

[0113] 4) Add network port 2 to namespace 2

[0114] 1. Add virtual interface 2 to the created network namespace.

[0115] #ip link set eth2 netns ns2

[0116] 2. Enable namespace ns2

[0117] &&ip netns exec ns2 ip link set eth2 up

[0118] 3. Configure IP addresses for the current namespace.

[0119] #ip netns exec ns2 ip addr add 1.1.1.20 / 24dev eth2

[0120] Accordingly, embodiments of the present invention may further include the following steps:

[0121] For example, Figure 2 This illustrates a system topology diagram of the server's internal structure, such as... Figure 2 As shown, different system resource groups correspond to different virtual network interface card (NIC) terminals, and correspondingly, different network namespaces. In the diagram, VF1, VF2, VF3, and VF4 represent different virtual NIC terminals, while netns1, netns2, netns3, and netns4 represent different network namespaces. Different IP addresses are configured for these different network namespaces: 1.1.1.10 / 24, 1.1.1.20 / 24, 1.1.1.30 / 24, and 1.1.1.40 / 24. Communication connections are established between the different virtual NIC ports through a virtual switch (openvswitch in the diagram).

[0122] Step 402: Based on the preset test command, control the multiple virtual terminals corresponding to the multiple virtual network card ports that have established communication connections to continuously send and receive data, and obtain the test results corresponding to the smart network card.

[0123] In this embodiment of the invention, a test network card script file is pre-set according to testing needs. Based on a preset test command, the network card test script file in the network card test program is run. A sending virtual network card port and a receiving virtual network card port are selected from multiple virtual network card ports. The network card test script file is used to make the sending virtual network card port send the test file to the receiving virtual network card port in a loop, and the sending time and receiving time are recorded. The consistency between the file received by the receiving virtual network card port and the test file is verified. Based on the data during the data transmission and reception process, the performance of the smart network card is obtained, so as to realize the testing of the smart network card and obtain the corresponding test results.

[0124] In this embodiment of the invention, a virtual switch is used to establish communication connections between different virtual network interface card (NIC) ports. NIC testing is then performed based on preset test commands. This allows for functional performance testing of multiple virtual NICs on a single server, eliminating the need for multiple servers to test multiple virtual NICs and reducing hardware investment. Furthermore, by automatically testing multiple virtual NIC ports connected to the virtual switch, the workload of testing personnel is reduced, saving testing time.

[0125] Optionally, step 402 may include the following steps:

[0126] Step 4021: Based on the first test command and the first test model indicated by the first test command, control the multiple virtual network card ports to continuously send and receive data, and obtain the bandwidth data during the data sending and receiving process as the network bandwidth test result corresponding to the smart network card.

[0127] In this embodiment of the invention, the test operation can be performed using software for traffic testing, such as iperf software. A first test command is used to instruct the network bandwidth of multiple virtual network interface card (NIC) ports to be tested. The first test command can be a TCP-based test command, such as: iperf -c 100.14.4.253 -t 60. Correspondingly, the first test model indicated by the first test command can be a TCP model. Based on the first test model indicated by the first test command, multiple virtual NIC ports are controlled to continuously send and receive data, and bandwidth data during the data transmission and reception process is obtained as the network bandwidth test result corresponding to the smart NIC.

[0128] Step 4022: Based on the second test command and the second test model indicated by the second test command, control the multiple virtual network interface card ports to continuously send and receive data, and obtain the data packet throughput, packet loss rate and transmission delay jitter time during the data sending and receiving process as the data loss test results corresponding to the smart network interface card.

[0129] In this embodiment of the invention, the second test command is used to instruct tests on the packet throughput, packet loss, and transmission delay jitter of multiple virtual network interface card (NIC) ports. The first test command can be a UDP-based test command, such as `iperf -c 100.14.4.253-t60 –u`. Correspondingly, the second test command indicates a UDP-based test model. Based on the second test command, multiple virtual NIC ports are controlled to continuously send and receive data, and the packet throughput, packet loss rate, and transmission delay jitter time during the data transmission and reception process are obtained as the data loss test results corresponding to the smart NIC. The data loss test results may include packet throughput, packet loss rate, and latency metrics.

[0130] In this embodiment of the invention, different types of tests can be performed on the smart network card based on different test commands, thereby improving the diversity of test types.

[0131] Optionally, embodiments of the present invention may further include the following steps:

[0132] Step 501: Evaluate the performance of the smart network card based on the network bandwidth test results and the data loss test results.

[0133] In this embodiment of the invention, based on network bandwidth test results and data loss test results, if the network bandwidth test results and data loss test results meet the expected results, the performance of the smart network card is evaluated as good; if the network bandwidth test results and data loss test results do not meet the expected results, the performance of the smart network card is evaluated as poor. For example, a packet loss rate of less than 1% can be considered as good performance of the smart network card. It is understood that the expected results can be set according to the test requirements, and this embodiment of the invention does not impose any limitations on this.

[0134] In one possible implementation, multiple virtual network interface card (NIC) ports can be controlled to continuously send and receive data, perform stress tests and load tests on the smart NIC, and other tests are not limited in this embodiment of the present invention.

[0135] For example, Figure 3 A flowchart illustrating a testing method for a smart network interface card is shown, such as... Figure 3As shown, the server hardware environment is initialized, enabling Single Root I / O Virtualization (SR-IOV) and network interface card (NIC) virtualization in the server's Basic Input Output System (BIOS). Multiple virtual NIC ports are obtained based on the virtualization of the smart NIC. The server's system resources are partitioned based on the system resources used by the processes in the virtual terminals corresponding to each virtual NIC port, resulting in system resource groups corresponding to the multiple virtual NIC terminals. Using a virtual switch, the network resources used by the processes in the virtual terminals corresponding to each virtual NIC port are allocated to different network namespaces to isolate them. Traffic tests are conducted on the virtual terminals corresponding to different virtual NIC ports to obtain the test results for the smart NIC.

[0158] In summary, the smart network interface card (NIC) testing device provided in this embodiment of the invention divides the server's system resources to obtain multiple system resource groups corresponding to multiple virtual NIC ports. These multiple system resource groups correspond to multiple resource limitation thresholds, which are used to limit the resource usage of system resources within each group. The multiple virtual NIC ports are obtained based on the virtualization of the smart NICs in the server, and each system resource group corresponds one-to-one with a virtual NIC port. Based on preset test commands, the traffic of multiple virtual terminals corresponding to the multiple virtual NIC ports is tested, yielding test results for the smart NICs. Thus, by dividing the server's system resources to obtain multiple system resource groups corresponding to multiple virtual NIC ports, the system resources corresponding to each virtual NIC port are independent and do not interfere with each other when testing the traffic of multiple virtual terminals corresponding to multiple virtual NIC ports. Furthermore, the resource usage of the system resources in the system resource groups corresponding to the virtual NIC ports reflects the resource load of the virtual NIC ports; that is, by limiting the resource usage of system resources, the resource load of the virtual NIC ports can be reduced to a certain extent. In this way, by setting resource limit thresholds to restrict the resource usage of system resources in system resource groups, the system resource load corresponding to each virtual network card port can also be limited to a certain extent. This allows for the construction of diverse test scenarios for testing different system resource loads, meeting diverse testing needs and improving the comprehensiveness of network card testing to a certain extent.
