According to the embodiment of the invention, the target equipment is locked through the registration center, the target equipment is ensured to be controlled by the same SDN controller at the same time, and the problem of repeated operation of the equipment under high concurrency is solved.
Considering that in order to ensure the continuous control of the device to implement various business operations, the method may further perform the following steps:
after the business operation is finished, releasing the lock to the target equipment through the registration center; sending a released notification to a target SDN controller; the released notification is used to prompt the target SDN controller to lock the target device.
In the embodiment of the present invention, the SDN controller controls the target device to execute the service operation, and when the service operation is completed, the target device is released from the lock through the registry, and then the target device becomes an unlocked state, which can be locked by another SDN controller through the registry. The SDN controllers can be mutually invoked, the invocation rule of the SDN can be preset, and after one SDN controller releases the lock on the target device, a released notice is sent to the target SDN controller according to the invocation rule, so that the target SDN controller locks the target device, and further, the target device is controlled to execute the service operation.
Considering that to facilitate controlling the locking process of the target device, the locking of the target device by the registry may be performed according to the following steps:
and sending a control instruction to the Agent client so that the Agent client locks the target equipment through the registry.
In the embodiment of the invention, the Agent client can be deployed in the network equipment operating system, and when the SDN controller is connected to the Agent client of the network equipment in a load distribution manner, the Agent client locks the network element equipment by the registry, so that other SDN controllers are prevented from operating the network element equipment.
It should be noted that the Agent client may be used in other steps in the embodiment of the present invention, for example, the Agent client may register the network element device in the registration center through manual configuration of an SN and network connection, the SDN controller may perform operations such as configuration issuing and service provisioning through the Agent client, and the Agent client may perform corresponding operations on the device through a command. After the business operation is completed, the agent informs the registry to release the lock, and the registry informs the waiting controller through the monitoring of the controller after releasing the lock. The controller that has aborted operation does not need to be notified.
In consideration of the process of re-executing the operation service due to the abnormal switching of the controller, etc., the following steps may also be performed in the process of controlling the locked target device to perform the service operation:
and recording the execution position information of the locked target equipment.
