Computer network simulation and visualization tool for educational purpose

This paper describes a web-based simulation and visualization tool for computer network. System is realised in Java programming language. The system enables process visualization and simulation in computer networks with arbitrary topology. The purpose of the system is to help students comprehend the basic principles of acting of one TCP/IP computers network as a part of the educational system of the computer network. Processes that occur in the computer network during the data exchange between the network devices are complex and they are executed in very short time slices, since the consumer is not able to follow and understand what happens in the computer network. The main purpose of our simulator is to present these processes visually. In addition, its features like topology editor and simulation of real-time network scenarios make it a suitable tool for undergraduate teaching as well as for research.
