A network node may transmit a configuration message to at least one network device of a plurality of network devices, the configuration message including updated configuration information for the at least one network device, determine whether to update a network inventory system based on a response to the configuration message, and update a record included in the network inventory system associated with the at least one network device based on results of the determination, the updating including updating the record with the updated configuration information.

Mechanism of obtaining up-to-date network inventory reliably and optimally

A method for restoring a network slice includes receiving a request to restore the network slice to a previous configuration, the previous configuration and a current configuration of the network slice being stored in a datastore, generating sets of subtrees from device-specific data in the current configuration and the previous configuration to be added, removed, or replaced in the current configuration, and restoring the network slice to the previous configuration based on the sets of subtrees.

Restoration of a network slice

In a method for managing a physical network, whether a slice owner of a virtual network slice in the physical network is allowed to view a network information message is determined based on at least one of classification metadata or allocation metadata associated with the virtual network slice. The network information message, which is received from the physical network, includes at least one of (i) an autonomous notification from a network node in the physical network or (ii) operational data for the network node in the physical network. The network information message is provided to the slice owner in response to determining that the slice owner is allowed to view the network information message.
