As the Internet continues to grow, the tasks of network management are becoming more and more difficult. Over the past few years, much effort has been given to implement the automation of network management. Ontology seems to be a promising technology for that purpose. However, only ontology alone may not easily achieve the goal of automatic network management. Thus under this background, policies may be added to enhance ontology-based network management. This paper just aims in the integration of ontology-based and policy-based approaches to automate network management. A common model for this integrated automatic network management is then proposed in the paper. To check the feasibility of this model, the paper provides a possible scenario.
