Abstract: Methods, apparatuses and computer readable storage mediums provide virtual network slicing without duplicating network configuration data (also referred to as network configuration information) on a slice-by-slice basis by maintaining a single physical network datastore including network configuration information for all network entities in the physical network, but generating slice views for respective virtual network slices as needed over time. Methods, apparatuses and computer readable storage mediums also enable configuration of a plurality of virtual network slices sharing a physical network infrastructure.

Abstract: 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.

Abstract: 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.
