Integrating heterogeneous IT/network management models using linked data

Today's ICT system necessarily involves multiple system domains complying with different management models. Integration of domain-specific management models is required to achieve, for example, agile fault localization in a huge ICT system, but this has not been efficiently achieved due to the difficulty in bridging multiple management models. To address this issue, we propose a systems management architecture reusing an existing standardized system management model for each domain and integrating them by introducing meta-data modeling. To show the feasibility of our proposal, we demonstrate that managed data of IT and network resources modeled by Common Information Model (CIM) and Shared Information Data (SID) model are bridged by meta-data modeling based on Resource Description Framework (RDF). The architectural design implies reduced effort thanks to use of well-deployed and standardized models and meta-data modeling language with its easy-to-use query language.
