Virtualization technology has been popularly used in teaching computer network works. In general, there are two tools that could be used when creating virtualized networks: simulators and emulators. Simulators mimic the basic functions of network devices but do not provide all the properties of the devices, whereas emulators behave exactly like the realistic network. Moreover, virtual computer systems, such as Windows and Linux could be connected to the network devices, such as routers and switches.
There are two well-known network simulation and emulation tools that are widely used in teaching network computer courses. They are PT (Packet Tracer) and GNS3 (Graphical Network Simulator), both addressing different features. PT is a network simulator that is designed by Cisco Networking Academy. It only implements limited real network device features and is mainly used to teach CCNA level courses. GNS3, based on Dynamips, Dynagen, and Qemu, is capable of building realistic networks.
In this paper, PT and GNS3 will be compared from the perspectives of capability and complexity. Strengths and weaknesses of each will be discussed. In addition, networks will be built in order to illustrate the points of our discussion.
