The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0024] The technical terms in the embodiments of the present application are briefly explained below.

[0025] DPU: DPU is a major category of the latest developed special-purpose processors. It is data-centric, input / output (I / O) intensive, and uses software-defined technology to support infrastructure resource layer virtualization. It is a new generation of computing chips that can improve computing system efficiency, reduce the total cost of ownership of the overall system, improve data processing performance, and reduce the performance loss of other computing chips. It provides a computing engine for high-bandwidth, low-latency, and data-intensive computing scenarios.

[0026] Kubernetes: Also known as K8s, it is a portable, extensible open source platform for automatically deploying, scaling, and managing containerized applications. K8s combines the containers that make up the application into logical units for easy management and service discovery.

[0027] Pod: Pod is the smallest basic unit for deployment and management in a K8s cluster. Pod can be used for collaborative addressing and collaborative scheduling. Pod is a collection of one or more containers, an abstract collection of one or a group of services (processes). Network and storage can be shared in Pod.

[0028] Virtual Machine (VM): VM is a computer environment implemented by software or hardware, which creates a virtual computer system on a physical computer, including virtual CPU, memory, hard disk, network interface, etc. This allows a physical computer to run multiple independent operating system and application instances at the same time, each instance runs in its own virtual machine, isolated from each other and does not interfere with each other.

[0029] Virtual Private Cloud (VPC): VPC allows users to create an isolated network environment in the cloud, ensuring that the user's resources are isolated from other users' resources. Users can select the Internet Protocol (IP) address range assigned to the VPC to define the IP address space of the VPC internal network.

[0030] Open Virtual Network (OVN): OVN is an open source project that provides software defined network (SDN) capabilities and can be used in conjunction with the Open Virtual Switch (OVS). OVN provides powerful virtual network capabilities such as logical switching, logical routing, firewall rules, and load balancing.

[0031] Logical router: In OVN, a logical router is responsible for forwarding business traffic between different logical switches. It is equivalent to a virtual router that can route data packets between different virtual networks.

[0032] High availability of links: High availability of links refers to the ability of links to switch from one link to another. In particular, when a link fails, high availability of links can ensure the rapid recovery of the network.

[0033] Currently, electronic devices deployed in non-public networks can access public networks through DPU. Figure 1 The scenario of electronic devices accessing a public network is described.

[0034] Figure 1 This is a scenario diagram of an electronic device accessing a public network provided by this application Figure 1 .like Figure 1As shown, the K8s cluster may include an electronic device (not shown) and DPU1 103. The electronic device may be deployed in a non-public network 110. A logical switch 104, a logical router 105, and a container are deployed in the electronic device. The container may include Pod 106, VM 107, Pod 108, and Vm 109. The detailed process of the electronic device accessing the public network 101 may include:

[0035] First, configure the routing information of DPU1 103 and the routing information of the container (one or more of Pod106, VM107, Pod108 and Vm109) on the logical router 105;

[0036] Secondly, based on the routing information of DPU1 103 and the routing information of the container, a link between the logical router 105 and DPU1 103 is constructed; and a link between the logical router 105 and the container;

[0037] Then, the logical router 105 may receive the service traffic sent by the container based on the link between the logical router 105 and the container, and then send the service traffic to the DPU1 103 based on the link between the logical router 105 and the DPU1 103; wherein the logical switch 104 is used to associate the DPU1 103 and the logical router 105;

[0038] Finally, DPU1 103 sends business traffic to the public network 101, thereby enabling the electronic device to access the public network; wherein the physical switch 102 is used to associate DPU1 103 with the public network 101.

[0039] It can be understood that DPU1 103 can act as a gateway to enable electronic devices to access the public network 101.

[0040] Exemplarily, the non-public network 110 may be a VPC.

[0041] like Figure 1 As shown, due to the routing information of DPU1 103 configured on the logical router 105, a single link between the logical router 105 and the DPU is constructed. However, the single link may be at risk of failure, thereby affecting the access of the electronic device to the public network.

[0042] That is to say, in the event that a link between an electronic device and a DPU fails, the entire network may become abnormal, making it impossible to achieve interaction between the non-public network and the announcement network.

[0043] Based on this, an embodiment of the present application provides a DPU-based link switching method, which is applied to an electronic device, and the electronic device is deployed in a non-public network. The method may include: based on the routing information of multiple DPUs, constructing a target link between the electronic device and the target DPU, and an alternative link between the electronic device and the alternative DPU, so that in the event of a failure in the target link, the target link is switched to the alternative link, and service traffic is sent to the alternative DPU through the alternative link. In this way, in the event of a failure in the target link, the link switching can be used to enable the electronic device to access the public network through the alternative DPU, thereby realizing the interaction between the non-public network and the public network, and ensuring the high availability of the link and the rapid recovery capability of the network.

[0044] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0045] Figure 2 1 is a flow chart of a link switching method based on a DPU provided in an embodiment of the present application, the method is applied to an electronic device, and the electronic device is deployed in a non-public network. Figure 2 As shown, the method may include the following steps.

[0046] S210: Determine routing information of multiple DPUs.

[0047] It should be noted that, in the embodiments of the present application, the DPU-based link switching method can be applied to a DPU-based link switching device, or an electronic device integrated with the device.

[0048] It should also be noted that multiple DPUs can be connected to electronic devices via network cables or optical fibers, or multiple DPUs can be connected to electronic devices via other methods, which is not limited in the embodiments of the present application.

[0049] Exemplarily, the routing information of the multiple DPUs may be obtained through a logical router in the electronic device. For example, the multiple DPUs may send their respective routing information to the logical router.

[0050] In some embodiments, determining routing information of multiple DPUs may include: creating multiple network cards on the multiple DPUs, obtaining media access control (MAC) addresses of the multiple network cards, wherein a network card is created on each of the multiple DPUs; obtaining IP addresses of the multiple DPUs; and determining routing information of the multiple DPUs based on the MAC addresses of the multiple network cards and / or the IP addresses of the multiple DPUs.

[0051] Exemplarily, the routing information of the multiple DPUs may include MAC addresses of multiple network cards and / or IP addresses of multiple DPUs.

[0052] Through this method, the routing information of multiple DPUs can be determined based on the MAC addresses of multiple network cards and / or the IP addresses of multiple DPUs. Subsequently, based on the routing information of multiple DPUs, links between electronic devices and multiple DPUs can be built, thereby facilitating link switching when a link fails, ensuring high availability of the link and rapid recovery capabilities of the network.

[0053] S220: Construct a target link between the electronic device and the target DPU, and an alternative link between the electronic device and the alternative DPU, using routing information of multiple DPUs.

[0054] The multiple DPUs include a target DPU and candidate DPUs.

[0055] It should be noted that after the electronic device obtains the routing information of multiple DPUs, it can know the location of a certain DPU when sending business traffic to the DPU, so that it can establish links with multiple DPUs.

[0056] It should also be noted that the link between the logical router in the electronic device and the container in the electronic device has been established. In other words, the logical router has learned the routing information of the container, and the container can also accurately send the service traffic to the logical router. Based on this, after the logical router learns the routing information of multiple DPUs, it can forward the service traffic received from the container to a certain DPU.

[0057] S230. When a target link fails, switch the target link to an alternative link, and send service traffic to an alternative DPU through the alternative link, so as to access a public network through the alternative DPU.

[0058] In some embodiments, the target link fails, which may include:

[0059] The target link is disconnected; and / or,

[0060] The peak bandwidth of the target link is less than the preset peak bandwidth; and / or,

[0061] The target DPU hardware is damaged.

[0062] It is understandable that the target link failure may also be caused by a power outage or a crash of the server of the target DPU.

[0063] It should be noted that, when the bandwidth peak of the target link is less than the preset bandwidth peak, and / or the hardware of the target DPU is damaged, the target link may not be disconnected.

[0064] It should also be noted that the preset bandwidth peak value may be set manually or by other means, and the embodiments of the present application are not limited to this.

[0065] It should be understood that if the bandwidth peak of the target link is less than the preset bandwidth peak, it means that the transmission capacity of the target link is limited and the service traffic cannot be transmitted.

[0066] Exemplarily, the hardware damage of the target DPU may be caused by a loose network cable or optical fiber of the target DPU, or may be caused by other reasons, which is not limited in the embodiments of the present application.

[0067] In some embodiments, there are multiple alternative DPUs; switching the target link to the alternative link may include: determining the priorities of multiple alternative DPUs; sorting the priorities of the multiple alternative DPUs from small to large, and selecting the DPU with the highest priority from the multiple alternative DPUs; switching the target link to: the alternative link between the electronic device and the DPU with the highest priority.

[0068] It should be noted that the priorities of multiple alternative DPUs can be determined based on the configuration information of multiple alternative DPUs (such as the memory used by the alternative DPUs, and the historical usage time), and / or the user's setting information (such as the alternative DPUs that the user prefers to use, and the service type used by the user).

[0069] For example, if a candidate DPU has used a large amount of memory, has been used for a long time, is not preferred by the user, and does not match the service type used by the user, it means that the priority of the candidate DPU is low.

[0070] It is understandable that the priorities of multiple candidate DPUs can be updated based on the configuration information of the multiple candidate DPUs and / or the user's setting information, so as to further meet the user's usage needs and improve the user's usage experience.

[0071] Through this method, since the alternative link is the link between the electronic device and the DPU with the highest priority, by switching the target link to the alternative link, the stability of business traffic transmission can be guaranteed when business traffic is subsequently transmitted based on the DPU with the highest priority.

[0072] It should be understood that, when the target link is not faulty, the target link may be congested due to excessive traffic. Based on this, two possible implementations of reducing the traffic on the target link are given below.

[0073] A possible implementation method is to divert the business traffic to obtain a first part of business traffic and a second part of business traffic when the target link has not failed; send the first part of business traffic to the target DPU through the target link, and send the second part of business traffic to the alternative DPU through the alternative link, so as to access the public network through the target DPU and the alternative DPU.

[0074] It should be noted that when diverting business traffic, the first part of the business traffic and the second part of the business traffic obtained by diversion can be made to be the same size, or the first part of the business traffic can be greater than the second part of the business traffic, or the second part of the business traffic can be greater than the first part of the business traffic. The embodiments of the present application are not limited to this.

[0075] Through this method, when the target link has not failed, the business traffic can be diverted so that the target link and the alternative link transmit the business traffic together, thereby avoiding link congestion caused by excessive business traffic on the target link and achieving load (i.e., target DPU and alternative DPU) balancing.

[0076] Another possible implementation method is to determine the priorities of the alternative DPU and the target DPU when the target link is not faulty; when the priority of the alternative DPU is higher than that of the target DPU, switch the target link to the alternative link, and send service traffic to the alternative DPU through the alternative link to access the public network through the alternative DPU.

[0077] It should be noted that the priority of the alternative DPU and the target DPU can be determined based on the configuration information of the alternative DPU and the target DPU (such as the memory used by the two DPUs, and the historical usage time of the two DPUs), and / or the user's setting information (such as the DPU that the user prefers to use, and the type of service used by the user).

[0078] Through this method, when the target link is not faulty, the target link can be switched to an alternative link between the electronic device and an alternative DPU with a higher priority. In this way, on the one hand, excessive service traffic on the target link can be avoided to cause link congestion; on the other hand, when the service traffic is subsequently transmitted based on the alternative DPU with the highest priority, the stability of service traffic transmission can be guaranteed.

[0079] In some embodiments, a container and a logical router are deployed in an electronic device; business traffic is sent to an alternative DPU through an alternative link to access a public network through the alternative DPU, including: the container sends business traffic to the logical router; the logical router sends business traffic to the alternative DPU through the alternative link to enable the container to access the public network through the alternative DPU.

[0080] It should be noted that the container and the logical switch can be associated through the logical switch, and the alternative DPU and the public network can be associated through the physical switch.

[0081] Through this method, the container deployed on the electronic device can access the public network through the alternative DPU, thereby realizing the interaction between the non-public network and the public network.

[0082] The embodiment of the present application provides a link switching method based on DPU, which is applied to an electronic device, and the electronic device is deployed in a non-public network. The method may include: based on the routing information of multiple DPUs, constructing a target link between the electronic device and the target DPU, and an alternative link between the electronic device and the alternative DPU, so that in the case of a failure of the target link, the target link is switched to the alternative link, and service traffic is sent to the alternative DPU through the alternative link. In this way, in the case of a failure of the target link, the link switching can be used to enable the electronic device to access the public network through the alternative DPU, thereby realizing the interaction between the non-public network and the public network, ensuring the high availability of the link and the rapid recovery capability of the network.

[0083] The following describes in detail the DPU-based link switching method provided in the above embodiment in combination with specific application scenarios.

[0084] Figure 3 This is a schematic diagram of a scenario in which an electronic device accesses a public network provided by an embodiment of the present application. Figure 2 .like Figure 3As shown, the K8s cluster may include an electronic device (not shown), DPU2 303 and DPU3 304. The electronic device may be deployed in a non-public network 311. A logical switch 305, a logical router 306 and a container are deployed in the electronic device. The container may include Pod 307, VM 308, Pod 309 and Vm 310. The detailed process of the electronic device accessing the public network 301 may include:

[0085] First, the routing information of DPU2 303, DPU3 304 and the routing information of the container (one or more of Pod307, VM308, Pod309 and Vm310) are configured on the logical router 306;

[0086] Secondly, based on the routing information of DPU2 303 and DPU3 304 and the routing information of the container, a target link between the logical router 306 and DPU2 303, an alternative link between the logical router 306 and DPU3 304, and a link between the logical router 306 and the container are constructed;

[0087] Then, the logical router 306 can receive the service traffic sent by the container based on the link between the container and the logical router 306, and send the service traffic to DPU2 303 through the target link. In the event of a target link failure, the target link is switched to an alternative link, and the service traffic is sent to DPU3 304 through the alternative link. The logical switch 305 is used to associate DPU2 303, DPU3 304 and the logical router 306;

[0088] Finally, DPU2 303 sends service traffic to the public network 301; in the event of a target link failure, DPU3 304 sends service traffic to the public network 301, thereby enabling electronic devices to access the public network. The physical switch 302 is used to associate DPU2 303, DPU3 304, and the public network 301.

[0089] It can be understood that DPU2 303 and DPU3 304 can act as gateways to enable electronic devices to access the public network 101.

[0090] like Figure 1 As shown, since the routing information of DPU2 303 and DPU3 304 is configured on the logical router 306, multiple links between the logical router 306 and the DPU are constructed. Therefore, in the event of a link failure, the electronic device can still access the public network through another link.

[0091] In addition, when there is no failure in the target link, the logical router 306 can divert the business traffic received from the container, send a part of the business traffic to DPU2 303 through the target link, and then send another part of the business traffic to DPU3 304 through the alternative link, so that the electronic device can access the public network through DPU2 303 and DPU3 304, thereby avoiding link congestion caused by excessive business traffic on the target link, and achieving load balancing on DPU2 303 and DPU3 304.

[0092] When there is no failure in the target link, the priorities of DPU2 303 and DPU3 304 can also be determined; when the priority of DPU3 304 is higher than that of DPU2 303, the target link is switched to the alternative link, and business traffic is sent to DPU3 304 through the alternative link, so that the electronic device can access the public network through DPU3 304, thereby avoiding link congestion caused by excessive business traffic on the target link, and ensuring the stability of business traffic transmission when business traffic is subsequently transmitted based on the DPU3 304 with the highest priority.

[0093] An embodiment of the present application provides a DPU-based link switching method, which can configure the routing information of multiple DPUs on a logical router, thereby building multiple links based on the multiple DPUs to access the public network. In the event of a link failure, the link can still be switched to use another link to access the public network, and the link switching is imperceptible to the container, ensuring the normal transmission of business traffic.

[0094] The preferred embodiments of the present application are described in detail above in conjunction with the accompanying drawings.

[0096] Based on the same inventive concept as the above embodiments, Figure 4 is a schematic diagram of the structure of a link switching device based on a DPU provided in an embodiment of the present application, such as Figure 4 As shown, the DPU-based link switching device 400 is applied to an electronic device, and the electronic device is deployed in a non-public network.
