Based on the OPNET Modeler V.14 NetDoctor application program package, the security policy method of switched networks
The publication is devoted to development, security of modeling technology of switched local area networks on the basis of the program package OPNET Modeler v.14. using the NetDoctor module. In this work the switched local area networks will be created using two different switching devices: hubs and switches. A hub transfers a package that has arrived at one of its inputs to all outputs regardless of the purpose of the package. On the other hand, the switch transfers the package to one or more outputs depending on the purpose of the package. In the recommended work for analysis and modeling of various networks the application program package of application program package of OPNET Modeller 14.0, performing the role of the commercial version offered free to educational use. The novelty is the method of modeling of local area networks on OPNET Modeler 14.0 with its subsequent extension and carrying out of research of modeled extended switched network.
