For the convenience of understanding and description, the following embodiments are described in detail with the server as an example.
[0025] It should be noted that the server can be a single device, or a system composed of multiple devices, i.e., a distributed server, and the present application does not make specific limitations thereon.
[0026] As shown in Figure 1, the embodiments of the present application provide an interworking method of an SDN controller and a network device, which comprises: Figure 1
[0027] S101: Obtain a topology relationship of a target storage network and a planning range; the topology relationship at least includes that the storage network is in the planning range and that the storage network is out of the planning range.
[0028] First, it is necessary to determine whether the target storage network vlan is in the planning range or out of the planning range, and the topology relationship here includes two cases that the storage network is in the planning range and that the storage network is out of the planning range.
[0029] S102: deploying a target application network corresponding to the target storage network at a corresponding preset position according to the topological relationship.
[0030] According to different topological relationships, different deployment processes are performed on the target application network. The difference between the deployment processes is mainly embodied in the deployment position of the application network.
[0031] In one embodiment, when deploying the target application network, the deployment position of the target application network is first determined according to the topological relationship, and the deployment position at least includes a cloud network system and an SDN system. If the storage network vlan is within the planning range, the vxlan network corresponding to the storage network vlan is created in the cloud network system, and if the storage network vlan is outside the planning range, the vxlan network corresponding to the storage network vlan is created in the SDN system. At the same time, if the storage network is established before the business network, according to whether the first flag with a specific identifier is carried in the business network, the target business network to be interconnected with the target storage network is determined; if the storage network is established after the business network, according to whether the second flag with a specific identifier is carried in the storage network, the target storage network to be interconnected with the target business network is determined. Finally, the route leakage configuration is issued through the listening mechanism.
[0032] It should be noted that the flag here refers to a single-bit flag used to record the state of the computer program. There are only two values, 1 (up) and 0 (down), which are usually stored in a fixed area in the memory. The program changes the value of the flag when the state changes, and the state is understood through the flag in other operations to determine the next operation. In other words, the flag can be used to help the program make complex conditional judgments.
[0033] The first flag refers to a mark variable that needs to be interconnected with the target storage network, and the second flag refers to a mark variable that needs to be interconnected with the target application network.
[0034] S103: Configuring a physical access port corresponding to the target storage network in the SDN system, and selecting the target storage network to issue an allowed configuration.
[0035] When configuring the storage device access port, the physical port of the storage network device access is configured in the SDN system, and the vlan allowed configuration is selected and issued by the storage network.
[0036] S104: judging whether the first determination flag in the target business network is turned on, if the first determination flag is turned on, the target business network is interconnected with the target storage network.
[0037] The target business network with the first determination flag turned on is interconnected with the target storage network.
[0038] In one embodiment, the target application network is a virtual extensible local area network corresponding to the target storage network, and the correspondence between the target storage network and the target application network is the same as the correspondence between a vlan network and a vxlan network.
[0039] In one embodiment, after interworking, traffic verification is also needed to confirm whether the target service network and the target storage network interwork successfully.
[0040] Further, when performing traffic verification, first, the traffic sent by the target storage device is acquired, and the traffic is attached with a request message of the target storage network vlan label; then, the SDN networking is used to add a message header of the target application network to the traffic, and the traffic is sent to a preset destination; after reaching the destination, the traffic is decapsulated to obtain the request message. The traffic of the storage device into the networking is a vlan label message, which is encapsulated with a vxlan message header after entering the SDN networking and forwarded to the destination. After reaching the destination, the traffic is decapsulated into a vlan message. One of the differences between the SDN networking and the ordinary networking is that the message is encapsulated and decapsulated in the networking.
[0041] In one embodiment, as shown in Figure 2 The SDN networking includes an external device layer, an access layer, a core device layer, and an external network layer. The corresponding physical access port is used to connect the external device, and the external device includes at least one of a storage device and a bare metal device.

[0043] A topology module is configured to acquire a topology relationship of a target storage network and a planning range, wherein the topology relationship at least includes the storage network in the planning range and the storage network outside the planning range.
[0044] A deployment module is configured to deploy a target application network corresponding to the target storage network at a corresponding preset position according to the topology relationship.
[0045] An issuing module is configured to configure a physical access port of the target storage network in an SDN system and select the target storage network to issue an allowed configuration.
[0046] An interworking module is configured to determine whether a first determination flag in the target service network is opened, and if the first determination flag is opened, the target service network and the target storage network are interworked.
[0047] As shown in Figure 4As shown, the embodiment of the present application further provides an interworking device of an SDN controller and a network device, comprising: at least one processor; and a memory in communication connection with the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to:
[0048] obtain a topology relationship between a target storage network and a planning range; the topology relationship at least includes that the storage network is in the planning range and that the storage network is out of the planning range; according to the topology relationship, deploy a target application network corresponding to the target storage network at a corresponding preset position; configure a physical access port corresponding to the target storage network in an SDN system, select the target storage network to issue an allowed configuration; judge whether a first judgment flag in the target service network is opened, if yes, interwork the target service network with the target storage network.
[0049] The embodiment of the present application further provides a nonvolatile computer storage medium, which stores computer executable instructions, and the computer executable instructions are set to:
[0050] obtain a topology relationship between a target storage network and a planning range; the topology relationship at least includes that the storage network is in the planning range and that the storage network is out of the planning range; according to the topology relationship, deploy a target application network corresponding to the target storage network at a corresponding preset position; configure a physical access port corresponding to the target storage network in an SDN system, select the target storage network to issue an allowed configuration; judge whether a first judgment flag in the target service network is opened, if yes, interwork the target service network with the target storage network.
