Description

Method and device for intelligent backup and recovery of network metadata in network management system

Technical field

Background technique

The user network service is increasing. When the development reaches a certain level, the original equipment cannot meet the requirements. It needs to perform the operation of adding points, and the original service needs to be switched to the newly added node. This is for expansion, and in the existing network, Due to the cancellation of the base station or the relocation of the base station, the tunnel needs to be penetrated through the tunnel of the device to cancel the service. This is to reduce the capacity or switch the service from the A port to the B port. This is port migration. When using the NMS for expansion and contraction, port migration, or migration and migration, it is inevitable that configuration failure will occur. Therefore, you must back up the NE data before expansion and contraction, port migration, and migration and migration. Use backup data to recover after expansion, port migration, or migration and migration failure.

The step of determining the backup network element of the pre-backup according to the connection topology relationship of the network element in the network;

That is, the network element affected by the network element is calculated according to the expansion and contraction, port migration, or migration to the network element. The network element is the backup network element, or it can be said that the network management client expands and shrinks all the resources. The network element affected by the port migration or migration is configured as a backup network element, for example, a network element that communicates with the expansion and contraction network element.

S102. Send a backup request to the network management server, so that the network management server backs up the network element data of the backup network element according to the backup request, where the backup request carries the network element information of the backup network element.

The step of the network management client generates a backup request according to the network element information, the user name, the operation name, the function ID, and the backup path of the backup network element, and sends the backup request to the network management server, where the network management is performed. The server classifies the backup request according to the backup mode, and the network element adapter completes the backup of the backup network element according to the classified backup request.

Navigation enters to trigger the recovery of the network element;

For the first trigger mode, the NMS client queries all the saved backup log files to allow the user to determine the recovery NEs that need to be restored. For the second trigger mode, the NMS client queries all backup log files and then navigates according to the navigation mode. The backup backup log file is filtered to select the recovery NE to be restored.

During the specific implementation, the user selects a log record in the backup log file, and displays information such as the NE name, version type, or recovery type of the backup log in the sub-list, and selects the recovery NE to be restored.

Of course, those skilled in the art can also select a specific recovery network element by other means according to actual needs. For example, the pre-recovered recovery network element is directly determined according to the network element topology relationship of the expansion and contraction network element, regardless of the backup network element that has been backed up.

S302. The network element information and the backup path of the recovery network element are used to generate a recovery request.
