A simulation environment for the evaluation of maintainability strategies in telecommunication networks based on satellite constellation

The paper presents a methodology for the application of the object-oriented approach to the modeling of telecommunication systems based on satellite constellation. The advent of these systems requires the design of suitable simulators able to consider the effect of the deterministic motion of the network elements. The proposed methodology has been effectively adopted by CSELT in the definition and design of a new simulation environment called CONSIM. The logical structures identified for the definition of the model of the specific system to be analyzed are described by presenting the functional architecture of the CONSIM environment and the characteristics of the main software modules and interfaces. The paper concludes by analyzing the actual development status and the candidate areas for possible further improvements.
