The ever-increasing heterogeneity of network elements, user devices, access technologies and services keeps posing requirements for the efficient management of infrastructures and resources. Autonomic network management is a promising paradigm but autonomic solutions are still far from being widely adopted, although self-organising capabilities have been introduced to network elements. The main reason for this is that autonomicity may raise serious trust and robustness issues. To address this, the need for appropriate coordination schemes is apparent. We propose a generic coordination scheme and a validation model which comes to verify that the desired correctness requirements are satisfied.
