A signaling interaction diagram of another embodiment of a network function virtualization platform resource management method of the present disclosure is shown in fig. 3C.
VNFM or VIM is created initially, or when a change occurs:
when the VNFM/VIM is initially created or updated, the NFVO sends a backup request to the virtualized device, the device packages its own data and configuration information, and sends the data and configuration information to the storage module for backup, and then, as long as the VNF managed therein has a change, the corresponding content of the storage module is automatically updated, thereby improving the risk resistance.
In 321, a first tier Node (NFVO) sends a backup request to the second tier node (VNFM/VIM).
At 322, the second tier node checks itself for analysis if a backup is needed. The following signaling interaction procedure is performed in case a backup is needed.

The tier two node uploads the packaged backup data to the storage module at 324-325. In one embodiment, the storage module may feed back backup success information to the first tier node so that the first tier node determines that the backup was successful. In one embodiment, if the first layer node does not receive feedback information of successful backup after a predetermined time, the second layer node is controlled again to upload the packaged data to ensure successful backup.

At 334, the first tier node notifies the second tier node of the data recovery.
At 335, the storage module sends the backup data to the second tier node.
In 336-337, the second tier node performs a data recovery process using the acquired data. In one embodiment, the second tier node may feed back recovery success information to the associated first tier node after completion of data recovery, so that the first tier node confirms that the second tier node it manages has completed data recovery.
A flowchart of yet another embodiment of a network function virtualization platform resource management method of the present disclosure is shown in fig. 4A. The NFVO serves as a top layer of the network function virtualization platform, can perform self-backup and self-recovery, and automatically and periodically backs up own data and configuration to respective storage modules after being established.
In step 401, when the first layer node is initially created, the first layer node acquires data and configuration information of the initially accessed second layer node and uploads the data and configuration information to the storage module as initial backup information of the first layer node. In one embodiment, the storage module of the first layer node uploading information may be a storage module shared by multiple NFVOs. In one embodiment, memory modules shared by multiple NFVOs may be numbered for each NFVO to illustrate differentiation.
In step 402, when the first level node determines that the second level node managed by the first level node changes, the information of the changed second level node is obtained as updated backup information of the first level node, so as to update the backup information of the first level node.
In step 403, when the information of the first layer node is lost, the first layer backup information is acquired from the storage module and the first layer node recovers itself.
By the method, the NFVO can be used as a top layer for self-backup and self-recovery, and data and configuration of the NFVO can be automatically and periodically backed up to respective storage modules after the NFVO is created, so that the processing efficiency of the first layer node and the automation degree of the platform are improved.

and automatically backing up the information of the managed VNM and the VIM to a storage module shared by a plurality of NFVOs, and automatically updating the corresponding content of the storage module as long as the managed VNM or the VIM changes, wherein when the NFVO itself generates data, the corresponding data can be automatically requested to be restored to the storage module. The risk is avoided conveniently, and backup data recovery is carried out when needed.
