Automated modeling of LonWorks building automation networks

Developing building automation systems requires careful planning of the applications and the network topology. Editing a model with up to 32,000 nodes manually is very time-consuming. In this paper, an automated approach for modeling LonWorks networks is presented. As a basis the existing LNS network operating system which is suited for integration and management purposes is used. It contains all information implicitly. Therefore, certain data has to be extracted to generate an explicit model for performance evaluation. The approach requires no additional effort for the network developer to acquire a complete model of the LonWorks network. The model is used for accumulated arrival rate estimation and is a basis for later queuing analysis
