Management functionality in a communications network is integrated using a design module for constructing a management information base (MIB). A unit of manageable physical resources is represented in the MIB by a management unit comprising a collection of managed objects representing actual physical and logical resources in the network. The functionality provided by those physical and logical resources is represented separately and independently from the objects representing those physical and logical resources. A realisation model associates classes of objects representing the functionality with classes of objects representing the physical and logical resources. In an embodiment, an Application model represents the functionality of network resources. An Implementation model represents the actual, specific implementation of how that functionality is carried out. A set of realisation associations links an application model to an implementation model to form a realisation model. Division and representation of physical and logical resources in the MIB by the management unit method allows substitution of physical and logical resources by different implementations of similar resource components without reconfiguring the parts of the MIB representing the functionality.
