Ontology-based Shared Management Information Modeling And Applications In The SDH Network

With the development and maturity of network management architecture, the problem of information sharing and interoperability between Operation Supporting Systems (OSS) has become more and more critical nowadays. Therefore, how to build shared information models aiming at facilitating information sharing has become a research topic that is under heated discussion in the field of network management. Many researchers are trying to solve this problem by leveraging Ontology theory which will definitely increase the expressive completeness of management information models and make it possible to build intelligent network management systems.Under this circumstance, this research dissertation focuses on and investigates into theoretical and technical issues related to ontology-based shared information modeling, model, and applications. First, with the help of ontology modeling and engineering, this paper proposes an ontology-based shared information modeling methodology, which is guided by the UTRAD (Unified TMN Requirements, Analysis and Design) and based on TMF SID (Shared Information Model). In this modeling methodology, we use OWL-DL as the description language. The whole management information modeling process works in a iterative manner, which evolves by modifying and improving the information model during previous iterations. Then, this research paper studies how to build shared management information model which is common to all networks and which is dedicated to SDH networks. Finally, we take a deeper look at the storage technologies of ontology-based management information model, and propose the mapping rules to store ontologies in relational database.
