Abstract

The network simulators and the network emulators have been worked out to avoid using the physical network components by testing of network applications and protocols. By means of them, we are able to test and to simulate behaviour of these protocols, applications and devices on any network, that can be created by the simulator. Without necessity of large investments, we are able to test these applications and to tune their possible deficiencies. The network simulators can be used principally to simulation of network behaviour and network protocols having certain properties. The network emulators are more fit for testing of behaviour of the respective network applications in specific conditions which can be created by the network emulator. This dissertation describes both the network simulators and the network emulators and gives an easy explanation to their function and their comparison.
