The increasing complexity of modern telecommunication systems causes difficulties in both teaching and learning computer networks. Students have to learn theories and specifications of different technologies but also need to practise configurations of specialized routers, switches and wireless access point which are not common devices. Usually such equipment is accessible only during classes and laboratory activities, thus students can use it in limited period of time. Network simulation software can resolve this problem.
The main idea and good practice examples of teaching computer networks using simulation software will be presented from the perspective of Cisco Networking Academy instructor with ten years experience
