[0038] As can be seen, the edge device in this application can create multiple sets of virtual network configurations corresponding to multiple dial-up lines. Each virtual network configuration includes a virtual network interface card (NIC), a virtual bridge, and a policy routing table. Local virtual machines can connect to the same group of virtual bridges through the virtual NICs in various virtual network configurations. This allows virtual machines to connect to the corresponding dial-up lines through each set of virtual network configurations and simultaneously use multiple dial-up lines to connect to the network.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] In traditional cluster environments, worker nodes typically have identical hardware and network resources, allowing virtual machines (VMs) to be configured using a uniform template. However, in edge computing scenarios, edge devices have varying network resources, such as different numbers of dial-up lines. Configuring VMs on an edge device using a uniform template can lead to insufficient utilization of all dial-up lines, resulting in wasted network resources. Therefore, this application provides a network configuration method that creates virtual network configurations for each dial-up line on the edge device. This allows VMs to simultaneously connect to the network using multiple dial-up lines, ensuring that VMs on the edge device fully utilize all dial-up networks on the device and avoiding network resource waste.

[0047] It should be noted that this method is applied to edge devices, which can run in a cluster environment. It should also be noted that the embodiments of this application do not limit the specific form of the edge device; for example, it can be a personal computer, a server, or other dedicated equipment. Furthermore, the embodiments of this application do not limit the specific cluster environment; for example, it can be k8s (Kubernetes) or other cluster environments.

[0048] Please refer to Figure 1 , Figure 1 A flowchart illustrating a network configuration method provided in an embodiment of this application. This method may include:

[0049] S101. Create multiple virtual network configurations corresponding to multiple dial-up lines; the virtual network configurations include virtual network cards, virtual bridges, and policy routing tables.

[0050] In this embodiment, the edge device can create multiple sets of virtual network configurations corresponding to multiple dial-up lines. Each virtual network configuration can include a virtual network interface card (NIC), a virtual bridge, and a policy routing table. Specifically, each dial-up line is configured with a corresponding virtual NIC, a virtual bridge, and a policy routing table. The virtual NIC can be deployed in a virtual machine to enable network communication. The virtual bridge connects the virtual NIC to the corresponding dial-up line and acts as a gateway between the virtual NIC and the dial-up line. The policy routing table establishes a one-to-one mapping between the virtual bridge, the virtual NIC, and the dial-up line, ensuring that traffic generated by the virtual NIC is only sent to the corresponding dial-up line via the virtual bridge, and traffic returned by the dial-up line is only sent to the corresponding virtual NIC via the virtual bridge. In this way, the edge device can ensure that the virtual machine can connect to each dial-up line through each set of virtual NICs, virtual bridges, and policy routing tables, and can simultaneously connect to the external network through these multiple dial-up lines.

[0051] Furthermore, to ensure that virtual network interface cards (NICs) and virtual bridges corresponding to the same dial-up line can communicate with each other, and that the virtual NIC can correctly send traffic to the virtual bridge, the virtual NIC and the virtual bridge need to be configured to the same virtual network, and the virtual bridge needs to be set as the default gateway of the virtual network. In addition, to ensure that the virtual network can exchange traffic with the corresponding dial-up line, the policy routing table corresponding to the dial-up line needs to record the mapping relationship between the virtual network and the default gateway of the dial-up line. Therefore, the edge device only needs to forward traffic in the virtual network to the default gateway of the corresponding dial-up line according to the policy routing table, and return traffic sent by the default gateway of the dial-up line to the corresponding virtual network. It should be noted that the configuration method of the virtual network in this application embodiment is not limited, as long as it can be determined that the IP addresses of the virtual NIC and the virtual bridge are configured based on the same network segment. The creation method of the policy routing table in this application embodiment is also not limited; relevant technologies of policy routing can be referred to.

[0052] Based on this, multiple virtual network configurations can be created corresponding to multiple dial-up lines, which may include:

[0053] Step 11: Create virtual network cards and virtual bridges for each dial-up line;

[0054] Step 12: Configure virtual networks for the virtual network card and virtual bridge corresponding to the same dial-up line, and set the virtual bridge as the default gateway of the virtual network;

[0055] Step 13: Create a policy routing table between the virtual network and the default gateway of the corresponding dial-up line, so as to map the virtual network card and virtual bridge corresponding to the dial-up line to the default gateway of the dial-up line one by one through the policy routing table.

[0056] Step 14: Configure a virtual network using the virtual network card, virtual bridge, and policy routing table corresponding to the same dial-up line.

[0057] Furthermore, the embodiments of this application do not limit the specific methods for creating virtual network interfaces and virtual bridges; for details, please refer to relevant technologies of virtual network interfaces and virtual bridges (such as Linux Bridge). For ease of management, a dedicated network management service for creating virtual network interfaces, virtual bridges, and policy routing tables can be set up in the edge device, allowing the edge device to create the aforementioned objects. The embodiments of this application also do not limit whether the virtual network interface is created inside or outside the virtual machine; it can be set according to actual application requirements.

[0058] S102. Connect the virtual machine to the virtual bridge in the same group through the virtual network card in each group's virtual network configuration, so that the virtual machine can connect to each dial-up line through each group's virtual network configuration and use multiple dial-up lines to connect to the network at the same time.

[0059] After creating the virtual network adapter and virtual bridge, the virtual machine needs to be connected to the virtual bridge in the same group through the virtual network adapter in each group's virtual network configuration, so as to connect the virtual machine to multiple dial-up lines and ensure that the virtual machine can communicate with multiple dial-up lines at the same time.

[0060] As mentioned above, virtual network adapters can be created outside the virtual machine. In this case, to connect the virtual machine to a virtual bridge via the virtual network adapter, the virtual network adapter must first be connected to a virtual bridge in the same group, and then the network adapter must be configured inside the virtual machine.

[0061] Based on this, creating virtual network cards and virtual bridges corresponding to each dial-up line can include:

[0062] Step 21: Create virtual network cards and virtual bridges for each dial-up line outside the virtual machine, and connect the virtual network cards and virtual bridges for the same dial-up line.

[0063] Correspondingly, connecting virtual machines to virtual bridges within the same group via virtual network adapters in each group's virtual network configuration can include:

[0064] Step 22: Configure the virtual network adapters in each group of virtual network configurations to the virtual machines.

[0065] As mentioned above, virtual network adapters can also be created inside the virtual machine. In this case, simply connect the network adapter to a virtual bridge in the same group outside the virtual machine.

[0066] Based on this, creating virtual network cards and virtual bridges corresponding to each dial-up line can include:

[0067] Step 31: Create virtual network cards corresponding to each dial-up line inside the virtual machine, and create virtual bridges corresponding to each dial-up line outside the virtual machine;

[0068] Correspondingly, connecting virtual machines to virtual bridges within the same group via virtual network adapters in each group's virtual network configuration can include:

[0069] Step 32: Connect each virtual network card in the virtual machine to the virtual bridge in the same group.

[0070] Furthermore, to facilitate virtual machine management, a virtual machine management service can also be set up in the edge device. Specifically, the virtual machine management service can initiate a virtual machine network card configuration request to the aforementioned network management service based on the dial-up line information of each dial-up line. Upon receiving the request, the network management service can obtain the dial-up line information of multiple dial-up lines from the dial-up management program, create corresponding virtual network cards, virtual bridges, and policy routing tables for each dial-up line, and send the network card configuration information of the virtual network cards (such as IPv4 address, subnet mask, MAC address, gateway address, etc.) to the virtual machine management service. The virtual machine management service can then configure the virtual network cards for the virtual machines according to the network card configuration information.

[0071] Based on the above embodiments, the edge device in this application can create multiple sets of virtual network cards, virtual bridges and policy routing tables corresponding to multiple dial-up lines, and can connect local virtual machines through the virtual network cards and virtual bridges. This allows virtual machines to connect to the corresponding dial-up lines through each set of virtual network cards, virtual bridges and policy routing tables, and can use these multiple dial-up lines to connect to the network simultaneously. This makes full use of all dial-up lines on the edge device and avoids network resource waste on the edge device.

[0072] Based on the above embodiments, considering that a cluster environment can simultaneously have traditional worker nodes and edge nodes, in order to configure virtual machines in the edge nodes individually, the cluster control device can send a special configuration file to the edge device to trigger the edge device to execute the network configuration method provided in this application. The specific details of the configuration file and the method for triggering the edge device to execute this network configuration method will be described below. In one possible case, this method may further include:

[0073] S201. When it is determined that the configuration information issued by the control device contains the edge virtual machine flag, obtain multiple dial-up lines.

[0074] In this embodiment, when the edge device receives configuration information for configuring a virtual machine from the control device, it only acquires multiple local dial-up lines if it determines that the configuration information contains an edge virtual machine identifier. If the edge device determines that the configuration information does not contain the edge virtual machine identifier, it can directly create a virtual machine network card according to the configuration file. In this way, the control device can ensure that the worker nodes and edge devices can use different methods to configure the network for the virtual machine by setting different configuration files for the worker nodes and edge devices, thus adapting to different configuration conditions on the worker nodes and edge devices. It should be noted that this embodiment does not limit the specific way the control device adds the edge virtual machine identifier to the configuration information; it depends on the type of configuration information. For example, when the configuration information is YAML configuration information, the control device can add the edge virtual machine identifier to the configuration information through annotations.

[0075] Furthermore, the embodiments of this application do not limit the dialing line obtained in this step to a pre-dialed dialing line. It also requires a dialing line dialed on-site based on the dialing configuration information, which can be selected according to actual application needs. For example, in some embodiments, the user can pre-diale on the edge device, and the edge device can directly obtain the pre-dialed dialing line; in other embodiments, the edge device can also obtain the dialing configuration information and perform on-site dialing based on that information to obtain the dialing line. It is worth noting that a dedicated dialing management program can be pre-set in the edge device, allowing the user or the edge device to dial based on this program.

[0076] Furthermore, this application embodiment does not limit the source of the dialing configuration information. It can be uploaded by the user to the control device and then distributed to the edge device by the control device through configuration information; or it can be directly input by the user into the dialing management program of the edge device. In the former case, when the edge device receives the configuration information distributed by the control device and determines that the information contains the edge virtual machine flag, it will further extract multiple sets of dialing configuration information from the configuration information and send them to the dialing management program for dialing. Subsequently, the edge device can either directly determine these multiple dialing lines according to the dialing configuration information in the configuration information, or determine multiple dialing lines according to the dialing line information of successfully dialed lines returned by the dialing management program.

[0077] Therefore, obtaining multiple dial-up lines can include:

[0078] Step 41: Send multiple sets of dialing configuration information from the configuration information to the dialing management program so that the dialing management program can make dialing based on the multiple sets of dialing configuration information;

[0079] Step 42: Determine multiple dialing lines based on multiple sets of dialing configuration information; or, determine multiple dialing lines based on the dialing line information of successfully dialed lines returned by the dialing management program.

[0080] It should be noted that the embodiments of this application do not limit the specific dialing process, nor do they limit the specific source of dialing configuration information (such as account, password, network port, etc.), which can be set according to actual application needs. It is worth pointing out that the dialing management program can be set up with a dedicated interface to receive dialing configuration information transmitted from edge devices. The embodiments of this application do not limit the specific form of this interface; for example, it can be an HTTP interface (Hypertext Transfer Protocol) or a CLI interface (command-line interface).

[0081] Furthermore, when the dialing configuration information can be directly entered by the user into the dialing management program of the edge device, the edge device can also directly obtain the dialing line information of successfully dialed lines from the program, and determine these multiple dialing lines based on this dialing line information.

[0082] Therefore, obtaining multiple dial-up lines can include:

[0083] Step 51: Receive the dialing line information returned by the dialing management program after completing the dialing based on the multiple sets of dialing configuration information entered by the user, and determine multiple dialing lines based on the dialing line information.

[0084] It should be noted that the dial-up lines mentioned in step 51 are all dial-up lines that have been pre-dialed on the edge device and are already connected to the external network. As mentioned above, a dial-up management program can be set up in the edge device to perform dialing and manage dial-up lines. Thus, the device only needs to obtain the aforementioned multiple dial-up lines from this dial-up management program.

[0085] Combining the two dialing methods mentioned above, this application can flexibly handle dialing tasks, thereby meeting various dialing needs.

[0086] S202. Create multiple virtual network configurations corresponding to multiple dial-up lines; the virtual network configurations include virtual network cards, virtual bridges, and policy routing tables.

[0087] S203. Connect the virtual machine to the virtual bridge in the same group through the virtual network card in each group's virtual network configuration, so that the virtual machine can connect to each dial-up line through each group's virtual network configuration and use multiple dial-up lines to connect to the network at the same time.

[0088] It should be noted that the descriptions of steps S202 and S203 are consistent with those of S101 and S102, and will not be repeated here.

[0089] Based on the above embodiments, the cluster control device in this application can specially issue configuration files with edge virtual machine flags to edge nodes, so as to trigger the edge devices to create corresponding virtual network configurations based on multiple local dial-up lines, thereby enabling individual configuration of edge devices.

[0090] Based on the above embodiments, the network configuration method described below will be fully explained with reference to specific flowcharts. Please refer to... Figure 2 , Figure 2 A flowchart illustrating another network configuration method provided in this application embodiment, the method may include:

[0091] 1. The network administrator of the Kubernetes edge device submits dial-up-related account, password, network port and other information to the dial-up program using the interface (HTTP and CLI) provided by the dial-up management program on the edge device, according to the dial-up configuration assigned by the telecom operator.

[0092] 2. The dial-up management program of the Kubernetes edge device dials up to the external network according to the dial-up configuration set by the administrator;

[0093] 3. When the Kubernetes control device distributes virtual machine YAML configuration files, it includes the edge virtual machine flag in the annotations of the YAML file: vm.xycloud.com / edge:'true';

[0094] 4. After receiving the virtual machine YAML configuration file from the Kubernetes control device, the virtual machine management service of the Kubernetes edge device checks whether the annotation of the configuration file contains the edge virtual machine flag vm.xycloud.com / edge:'true'. If it does not exist, it generates a direct virtual machine network card according to the configuration; otherwise, it proceeds to the next step.

[0095] 5. The virtual machine management service of the Kubernetes edge device initiates a request to the network management service to allocate virtual machine network interface card configurations;

[0096] 6. After receiving the request from the virtual machine management service, the Kubernetes edge device network management service reads the dial-up line information stored in the dial-up management program and obtains all dial-up line names.

[0097] 7. The Kubernetes edge device network management service creates a virtual bridge (Linux bridge) and a virtual network interface card (NIC) for each dial-up line, and adds the virtual NIC to the virtual bridge. Both the virtual NIC and the virtual bridge have statically configured IPv4 addresses, and the virtual bridge serves as the default gateway within that virtual network. The Kubernetes edge device network management service adds a policy route based on the source IP address (network segment) for each virtual network (the network connected by the virtual bridge). The default gateway in the policy routing table is the same as the default gateway obtained by the dial-up management program on that line. The purpose of this step is to ensure a strict one-to-one mapping between the virtual machine's virtual NIC and the dial-up line; that is, traffic from the virtual NIC will only pass through the corresponding dial-up line.

[0098] 8. The Kubernetes edge device network management service returns the generated list of virtual network interface card (NIC) configurations to the virtual machine management service. The configurations include the virtual NIC name, IPv4 address, subnet mask, MAC address, gateway address, etc.

[0099] 9. After receiving the virtual machine network card configuration returned from the network management service, the virtual machine management service of the Kubernetes edge device adds the virtual network card to the virtual machine.
