Discrete-Event Simulation of Network Systems Using Distributed Object Computing

A modeling and simulation environment supporting scalable network system analysis and design is described. The environment, called DEVS/DOC, enables simulation modeling of network systems where hardware and software layers of the system are modeled separately and combined based on the concept of quantum Distributed Object Computing. The key benefit of this reengineered simulation environment is support for scalability. Of particular interest is the ability to evaluate alternative network configurations where many software and hardware components of a system can be accounted for and analyzed simultaneously. A series of simulations are developed to show the capabilities of distributed object computing modeling and its realization using the DEVSJAVA modeling and simulation environment.
