Object Oriented Hybrid Network Simulation

The simulation of complex contemporary hybrid communication networks is a daunting task and cannot be handled by the array of conventional network simulation tools available today. This paper discusses the key issues involved in the visualization and simulation of complex hybrid networks and presents the design of an object-oriented hybrid network simulator being developed at the Center for Satellite and Hybrid Communication Networks (a NASA center for the commercial development of space), University of Maryland at College Park. This software incorporates a complex system simulation paradigm, advanced visualization techniques, a flexible interface and an object-oriented database to allow the simulator to be used not only as a network simulation tool, but also as a network design tool, as a network performance evaluation tool, and as part of an intelligent network management software.
