Abstract: The present invention relates to a method for reconfiguring data network nodes (3, 5, 7) in a data network (1), the method comprising the steps of: storing information comprising: a first set of data (25I-25V) representing a current configuration of the data network nodes (3, 5, 7), and a second set of data (27I-27V) representing a desired configuration of the data network nodes (3, 5, 7); generating, from the first set of data (25I-25V) and the second set of data (27I-27V), an information entity (33, 33I-33V) representing a difference between the current configuration and the desired configuration, and reconfiguring at least one of the data network nodes (3, 5, 7) using the information entity (33, 33I-33V).

Abstract: The present disclosure relates to a network management system node for re-configuring a set of data network nodes in a data network in response to a change management request requesting a creation of a network service to be performed in the data network. The network management system node is characterized in that it includes a processing unit configured to store each change of network service information in created, added and/or updated data network nodes in the resulting set of data network nodes established by the re-configuration of the set of data network nodes based on the change management request requesting the creation of the network service as a change-set of network service information, and associate the change-set of network service information with a network service instance indicating the moment of the creation of the network service.
