[0026] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only the parts related to the present application, rather than all structures, are shown in the accompanying drawings.

[0027] Embodiment 1

[0028] Figure 1 A flowchart of a method for interconnecting virtual and real devices provided in Example 1 of the present application is shown in FIG. Figure 1 As shown, the virtual-real device interconnection method provided in this embodiment can be applied to a virtual-real device networking system, where the virtual-real device networking system is provided with an SDN device, and the SDN device is connected to multiple physical devices, and specifically may include the following steps:

[0029] Step 101: upon receiving a user's networking requirement for a target virtual device, obtain interface information of the target virtual device from an SDN device according to the networking requirement.

[0030] In this step, the target virtual device includes a target virtual device and a target physical device, and the target physical device is at least one physical device among multiple physical devices connected to the SDN device. That is, there may be one or more target virtual devices involved in this embodiment, and there may also be one or more target physical devices.

[0031] In a specific example, the target virtual device may be an MES, ERP or other system, and the target physical device may be a local physical device that is directly accessed through the fixed interface, physical port or VLAN of the SDN device, or a remote physical device that requires VPN resources or dedicated lines to be opened.

[0032] In addition, the networking requirements include the connectivity requirements between the target virtual device and the target physical device. Users can input the networking requirements for the target virtual and physical devices in text or graphic form. In text form, the identifier of the target virtual device and the identifier of the target physical device as well as the connectivity requirements between them can be indicated so that they can be processed correctly after receiving the networking requirements.

[0033] In a graphical manner, virtual devices and physical devices can be graphically visualized in advance, and the user can connect the virtual devices and physical devices. By identifying the two ends of the connection line, the identifier of the target virtual device and the identifier of the target physical device that need to be connected can be obtained, wherein a connection line represents a connectivity requirement.

[0034] In this step, after receiving the networking requirements, the virtual interface information of the target virtual device and the port information of the target physical device connected to the SDN device will be obtained from the SDN device based on the identifier of the target virtual device and the identifier of the target physical device involved in the networking requirements. The virtual interface information and port information are the interface information of the target virtual and real devices obtained in this step.

[0035] Step 102: Create a virtual connection device according to the networking requirements and the interface information of the target virtual and real devices.

[0036] In this step, the virtual connection device may be a virtual switch and / or a virtual router, wherein the virtual switch is mainly used for layer 2 networking, and the virtual router is used for layer 3 networking.

[0037] Specifically, the network hierarchy between each target physical device and each target virtual device may be determined based on the interface information and connectivity requirements of the target virtual and real devices; and then a virtual connection device may be created based on the network hierarchy.

[0038] Since the number of target entity devices involved in this embodiment may be multiple, and the network segments between the target entity devices may be the same or different, when determining the network hierarchy architecture, it will involve the second-layer networking for the same network segment and the third-layer networking for different network segments.

[0039] Therefore, when determining the network hierarchy architecture, it is possible to determine whether the target physical device is in the same network segment. Specifically, at least one target physical device that needs to be connected to the same target virtual device can be determined based on connectivity requirements to obtain a set of physical devices corresponding to the target virtual device; then, for the set of physical devices corresponding to any target virtual device, determine whether the target physical devices in the set of physical devices belong to the same network segment.

[0040] If so, a two-layer network architecture is determined between the target virtual device and the target physical device in the corresponding physical device set; otherwise, a three-layer network architecture is determined between the target virtual device and the target physical device in the corresponding physical device set.

[0041] Among them, the network segment determination is only required when connecting to the same target virtual device. Therefore, in order to facilitate the determination, the target physical devices connected to the same target virtual device can be regarded as a set, and then the target physical devices in the set are determined to be in the same network segment.

[0042] It should be noted that the method of determining the same network segment can refer to the network segment-related technologies, which will not be repeated here.

[0043] If they belong to the same network segment, only Layer 2 networking is required to achieve connectivity, corresponding to the Layer 2 networking architecture. If they do not belong to the same network segment, Layer 3 networking is required to achieve connectivity, corresponding to the Layer 3 networking architecture.

[0044] After the hierarchical architecture is determined, the corresponding virtual connection devices to be created will also be clearly identified. That is, if it is a two-layer networking architecture, a virtual switch is created between the target virtual device and the target physical device, and the virtual switch is the virtual connection device; if it is a three-layer networking architecture, a virtual router is created between the target virtual device and the target physical device, and the virtual router is the virtual connection device.

[0045] It should be noted that in a certain set, there are multiple target physical devices in the same network segment and at least one target physical device in another network segment. At this time, the corresponding hierarchical architecture can be a complex hierarchical architecture. For this complex hierarchical architecture, it is necessary to create a virtual switch and a virtual router. You can first connect multiple target physical devices in the same network segment to a virtual switch, and then connect the virtual switch and the target physical devices in other network segments to the virtual router.

[0046] Furthermore, if there are multiple target physical device groups (ie, multiple target physical devices) in the same network segment, each target physical device group needs to create its own corresponding virtual switch.

[0047] It should be noted that the virtual connection device in this step is dynamically created based on the networking requirements. In order to more clearly describe the dynamic creation process, a specific example can be used for illustration. Figure 4 , Figure 4 A structural diagram of the interconnection between virtual and real devices provided in Example 1 of the present application.

[0048] like Figure 4 As shown, the physical device includes local physical resource 1, local physical resource 2 and remote physical resource. The networking requirement may be to connect local physical resource 1 to the ERP system, and to connect local physical resource 1, local physical resource 2 and remote physical resource to the MES system. Based on the records of the SDN device, local physical resource 1, local physical resource 2 and remote physical resource are all in different network segments.

[0049] Based on the requirement of connecting local entity resource 1 to the ERP system, a virtual switch can be created for local entity resource 1; based on the requirement of connecting local entity resource 1, local entity resource 2 and remote entity resources to the MES system, since local entity resource 1, local entity resource 2 and remote entity resources are in different network segments, a virtual switch needs to be set for each physical device, and then a virtual router is set to connect each virtual switch to form a three-layer network.

[0050] Based on the above creation strategies, it is concluded that a virtual switch is created for each of the local entity resource 1, the local entity resource 2 and the remote entity resource, namely the local network 1, the local network 2 and the remote network, and then a virtual router is created to connect the local network 1, the local network 2 and the remote network. Then the local network 1 is connected to the ERP system to realize the connection between the local entity resource 1 and the ERP system, and the virtual router is connected to the MES system to realize the connection between the local entity resource 1, the local entity resource 2 and the remote entity resource to the MES system.

[0051] Step 103: Connect the target virtual and real device to the virtual connection device to connect the target virtual and real devices.

[0052] In this step, after the aforementioned virtual connection device is created, the target virtual device and the target physical device can be connected according to the aforementioned network hierarchy. If it is a two-layer networking architecture, the target virtual device and the target physical device are connected to the virtual switch; if it is a three-layer networking architecture, the target virtual device and the target physical device are connected to the virtual router.

[0053] In a specific example, if a layer-2 networking architecture is formed between the target physical device and the target virtual device, the target physical device and the target virtual device may be connected to the created virtual switch.

[0054] If a three-layer network architecture is formed between the target physical device and the target virtual device, the target physical device and the target virtual device can be connected to the created virtual router.

[0055] If it is the aforementioned complex networking architecture, multiple target physical devices in the same network segment are first connected to a virtual switch, and then the virtual switch and the target physical devices in other network segments are connected to a virtual router.

[0056] In this embodiment, it is applied to a virtual-real device networking system, in which an SDN device is provided, and the SDN device is connected to a plurality of physical devices. When the user's networking requirements for the target virtual-real device are received, the interface information of the target virtual-real device is obtained from the SDN device according to the networking requirements; then a virtual connection device is created according to the networking requirements and the interface information of the target virtual-real device; finally, the target virtual-real device is connected to the virtual connection device to connect the target virtual-real device. Based on this, in this embodiment, as long as the physical device is connected to the SDN device and the networking requirements are directly input, a virtual connection device can be created, so that the virtual-real device can be successfully interconnected through the virtual connection device, without the need for manual configuration, and the interconnection efficiency is higher, and only the networking requirements need to be input to perform networking according to the networking requirements, which is more flexible.
