Abstract: [slo] [eng]
Diplomová práca sa zaoberá architektúrou siete IMS a analýzou vplyvu zaťaženia na túto sieť. Architektúra IMS je sieťou novej generácie. Konverguje pevné a mobilné siete a umožňuje rýchle zavádzanie nových multimediálnych služieb. Prvá kapitola je zameraná na popis architektúry IMS, jej jednotlivých prvkov a ich funkciu. Druhá kapitola je venovaná základným protokolom v systéme IMS, hlavne signalizačnému protokolu SIP. Tretia kapitola sa zameriava na problematiku teórie front. Pre simuláciu siete IMS bolo vybrané prostredie Open IMS Core popísané v štvrtej kapitole. Ďalšia kapitola je venovaná nástroju IMS Bench SIPp slúžiacemu ku generovaniu a testovaniu protokolu SIP so zameraním na IMS. Záverečná kapitola sa venuje realizácii vlastnej IMS siete. Začiatok tejto kapitoly sa zaoberá popisom jednotlivých spojení, generovaných nástrojom IMS Bench SIPp. V ďalšej časti sú vytvorené a podrobne analyzované záťažové testy zamerané na realizovanú IMS sieť. V závere kapitoly popisujeme realizáciu reálneho hovoru medzi zariadeniami s operačným systémom Android. This master’s thesis deals with architecture of the IMS network and analysis of the affects when loading the network. Architecture of IMS is a network of new generation. It convergates fixed and mobile networks and it enables quick installation of new multimedia services. The first chapter is focused on the description of the IMS architecture, its components and their function. The next chapter is devoted to the main protocols in the IMS system. It is mainly about signalization protocol SIP. The third chapter focuses on the queueing theory. For simulation of the IMS network, Open IMS Core enviroment was chosen, described in the fourth chapter. Next chapter is dedicated to the IMS Bench SIPp tool used for generating and testing the SIP protocol with focus on the IMS. The final chapter dedicates to the realization of an IMS network. The begining of this chapter deals with the description of individual conections generated by the IMS Bench SIPp tool. In the next part load tests focused on the created IMS network are created and analyzed in detail. The end of the chapter describes the implementation of the real finished call between devices and the Android operating system.
