For the security of telecommunication networks on the application program package OPNET Modeler v.14.5 and the use of the NetDoctor module

Abstract

The work is focused on modeling in OPNET Modeler v.14.5 wireless subscriber access network for its analysis and research by using and applying the NetDoctor module to ensure the security of the built network. Wireless communication is used, as it is accepted, in networks, connecting and wired (cable) means, and give the opportunity to take a convenient, fast and economical solution of problems arising in the process of solution and modernization of cable networks. Wireless communications, therefore, should be considered not a complete alternative to cable networks, but only an alternative technology for the implementation of individual segments or even entire levels of the designed, extensible or modernizing computer network. Detection of used erroneous technologies in the process of building and modeling of telecommunication networks ensures the security of their functioning and predicts their reliable building structure at their design. In our work we use the NetDoctor module of the program package of OPNET Modeler v.14.5 to test the security of the built wireless network.
