This project concerns a study of performance analysis tools dedicated to computer networking. This investigation was carried out in order to assess the abilities of these tools to represent and simulate models under real-time constraints. Two software packages have been tested and evaluated QASE RT, an information system simulator, and OPNET, a communication system simulator. The method employed consisted in four steps: theoretical studies, simulation tool evaluation, simulation and reporting. Two networks have been used to illustrate the tools' functionalities: the actual network at the Department of Computer and Information Science (IDA) and a client/server-oriented network. The results of the simulations applied on these models are discussed. The advantages and disadvantages of the evaluated tools are presented at the end of this document.
