A method for managing a physical network, the method comprising: receiving a network information message from the physical network, the network information message including 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; identifying (S2202) an entity instance at the network node having originated the network information message; determining whether a slice owner (110-S) of a virtual network slice in the physical network is allowed to view the network information message based on at least one of network entity classification metadata stored as a classification entry in network configuration information for network entities in a physical network datastore , said classification entry comprising an entity's unique identifier, and a model schema required to identify the network entity including key definitions, or allocation metadata stored as an allocation entry in the network configuration information for network entities in the physical network datastore , said allocation metadata comprising a virtual network slice, a unique identifier matching a classification entry being referred to, a set of unique keys identifying the network entity instances and accessibility information for the allocation metadata; identifying a classification entry for an entity type based on the entity instance; determining whether the slice owner (110-S) is allowed to view the network information message based on the classification entry for the entity type in the classification metadata; and providing the network information message to the slice owner (110-S) in response to determining that the slice owner (110-S) is allowed to view the network information message. receiving a network information message from the physical network, the network information message including 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; identifying (S2202) an entity instance at the network node having originated the network information message; determining whether a slice owner (110-S) of a virtual network slice in the physical network is allowed to view the network information message based on at least one of network entity classification metadata stored as a classification entry in network configuration information for network entities in a physical network datastore , said classification entry comprising an entity's unique identifier, and a model schema required to identify the network entity including key definitions, or allocation metadata stored as an allocation entry in the network configuration information for network entities in the physical network datastore , said allocation metadata comprising a virtual network slice, a unique identifier matching a classification entry being referred to, a set of unique keys identifying the network entity instances and accessibility information for the allocation metadata; identifying a classification entry for an entity type based on the entity instance; determining whether the slice owner (110-S) is allowed to view the network information message based on the classification entry for the entity type in the classification metadata; and providing the network information message to the slice owner (110-S) in response to determining that the slice owner (110-S) is allowed to view the network information message. <EOS>
