Reconciling network management data

A system for managing network management data, the system comprising:

• a memory;
• a processor communicatively coupled to the memory;
• and
• a network manager communicatively coupled to the memory and the processor, the network manager is configured for performing a method comprising:
• determining that a first version of a set of network management data and a second version of the set of network management data have been created, the first and second versions of the set of network management data each being associated with a plurality of managed entities in a network and comprising at least an identifier of each of the plurality of managed entities;
• determining that the identifier of at least one of the plurality of managed entities in the first version of the set of network management data fails to match any of the identifiers in the second version of the set of network management data;
• creating, based on the determining the identifier of at least one of the plurality of managed entities in the first version of the set of network management data fails to match any of the identifiers in the second version of the set of network management data, a first network graph based on the first version of the set of network management data, the first network graph comprising a first set of entities in the plurality of managed entities;
• creating, based on the determining the identifier of at least one of the plurality of managed entities in the first version of the set of network management data fails to match any of the identifiers in the second version of the set of network management data, a second network graph based on the second version of the set of network management data, the second network graph comprising a second set of entities in the plurality of managed entities;
• assigning a similarity metric between at least one or more entities in the first set of entities and one or more entities in the second set of entities;
• and
• determining that at least a first entity in the first set of entities and at least a second entity in the second set of entities are identical entities based on the similarity metric assigned between the first entity and the second entity being one of equal to and above a first given threshold.

A computer program product managing network management data, the computer program product comprising:

• a non-transitory storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
• determining that a first version of a set of network management data and a second version of the set of network management data have been created, the first and second versions of the set of network management data each being associated with a plurality of managed entities in a network and comprising at least an identifier of each of the plurality of managed entities;
• creating, based on the determining the identifier of at least one of the plurality of managed entities in the first version of the set of network management data fails to match any of the identifiers in the second version of the set of network management data, a first network graph based on the first version of the set of network management data, the first network graph comprising a first set of entities in the plurality of managed entities;
• creating, based on the determining the identifier of at least one of the plurality of managed entities in the first version of the set of network management data fails to match any of the identifiers in the second version of the set of network management data, a second network graph based on the second version of the set of network management data, the second network graph comprising a second set of entities in the plurality of managed entities;
• assigning a similarity metric between at least one or more entities in the first set of entities and one or more entities in the second set of entities;
• and
• determining that at least a first entity in the first set of entities and at least a second entity in the second set of entities are identical entities based on the similarity metric assigned between the first entity and the second entity being one of equal to and above a first given threshold.
