Simulace počítačové sítě v programu OPNET

Abstract

Intention of thesis is to approach the functions of the OPNET Modeler program, creating simulations of data transmission in different types of computer networks using this program, as well as instructions for the creation of simulations and compare the results obtained with results measured on real devices in the school laboratory. Compared are networks using OSPF and RIP protocol, and wireless network using Wi-Fi connection. The delay of connected network was measured with the program ping and troughput of network with the program iperf. These two values were measured in simulations in OPNET Modeler program and eventually compared with real values.
