20.500.12556/DKUM-66627 Simulations of VoIP applications in INET framework Simuliranje aplikacij VoIP v ogrodju INET This master's thesis describes the support for modelling Voice over Internet Protocol (VoIP) applications in the INET Framework. First, it briefly presents the VoIP technology and factors responsible for the VoIP quality of service. Next, the thesis moves on to discuss the OMNeT++ environment and the INET Framework, their installation and usage. Following this, it examines all of the INET packages and modules available for VoIP modelling, with all VoIP-related INET examples then shortly described and tested. By using INET, our own network and application models are created and simulated using different parameters. Comparisons of the simulation results are carried out and some of the best-found parameters for the VoIP communications are presented. At last, the calculation of jitter by using the obtained simulation results and Excel program is described, because jitter is not shown in the simulation results in INET. Internetna telefonija temelji na tehnologiji VoIP (“Voice over Internet Protocol”- govor preko medmrežnega protokola), ki omogoča prenos avdio signalov preko interneta. Pretvarja analogne telefonske signale v bite in te nato v paketih IP (“Internet Protocol” - medmrežni protokol) prenese preko interneta do cilja, kjer se ti biti ponovno pretvorijo v analogni zvok, ki ga je možno poslušati preko zvočnikov ali s slušalkami. Klici VoIP so vedno boljši, zanesljivejši in se vse pogosteje uporabljajo. Cilj tega magistrskega dela je bil raziskati, kako dobro je VoIP podprt v ogrodju INET. Na kratko je opisan omrežni simulator OMNeT++.Potem je podrobno opisana podprtost VoIP-a v okolju INET. Opisani so paketi in moduli INET-a, pomembni za raziskavo. Opisani so primeri aplikacij v povezavi z VoIP-om, ki so že na voljo v INET-u, pa potem naših lastnih modelov in simulacij. Prikazan je bil način računanja trepetanja s pomočjo programa Excel in dobljenih rezultatov za primere z RTP in UDP. voice over internet protocol performance analysis simulation real-time transport protocol user datagram protocol govor preko medmrežnega protokola analiza učinkovitosti simulacija transportni protokol za realni čas uporabniški datagramski protokol true true false S.
