Teaching and training of network protocols with DEVS-suite

This paper presents a robust simulation environment targeted for teaching and learning the complex dynamics of computer networks. The general-purpose DEVS-suite simulator supports animation with I/O and state trajectories of computer network models developed using parallel DEVS modeling approach. The simulator offers high-level model abstraction as compared with simulators such as NS-2. The combined capabilities afforded by the robust DEVS-suite simulator assists in understanding the fundamentals of computer network topologies and the logics of communication protocols. This newly developed DEVS-Suite offers an expressive, yet relatively simple to use, simulation environment for students and educators to develop and experiment with computer network models.
