Abstract
Ovaj rad jest napravljen s ciljem opažanja važnosti podvorbenih sustava u kontekstu telekomunikacijskih mreža. Razrađena je tematika pojma podvorbenih sustava, vrste te njihovih načina ponašanja. Iznimno važna je uloga paketnog čvora te je razrađena u zasebnom poglavlju. Za potrebe izrade ovog rada napravljeni su modeli sustava s prioritetnim posluživanjem s jednim, dva te s tri poslužitelja. Mreže su konfigurirane i sastavljene kako bi se na njima mogle odvijati simulacije u cilju opažanja ponašanja sustava u raznim uvjetima pri čemu je ključan parametar kašnjenje. Glavni dio rada predstavljaju simulacije provedene na stvorenim modelima u Simulinku. Provedene su simulacije na način da su se ispitivale performanse sustava u ovisnosti o intenzitetu dolazaka korisnika na svakom poslužitelju, pa posebno provjeravajući performanse za svaku klasu korisnika. U posljednjim poglavljima su predstavljeni i komentirani rezultati dobiveni analizom. Najvažniji zaključci koji se izvlače nakon izrade ovog rada su da kod sustava s više poslužitelja i načinom prioritetnog posluživanja prvi poslužitelj u najvećoj mjeri diktira ponašanje sustava, a prosječno vrijeme zadržavanja direktno ovisi o intenzitetu dolazaka korisnika te s njegovim povećanjem raste. Kada su analizirane klase zasebno, može se zaključiti da klase s nižim prioritetima imaju sve oštrije poraste vremena zadržavanja u sustavu što je bio i očekivan rezultat.
Abstract (english)
This paper was made with the aim of observing the importance of sub-system systems in the context of telecommunication networks. The topic of the concept of queuing systems, types and their ways of behavior is elaborated. The role of the packet node is extremely important and is elaborated in a separate chapter. For the purposes of this paper, system models with priority serving with one, two and three servers were made. Networks are configured and assembled so that simulations can take place on them to observe the behavior of the system in various conditions, where the key parameter is the delay. The main part of the paper is the simulations performed on the created models in Simulink. Simulations were performed by examining the performance of the system depending on the intensity of user arrivals on each server, and checking the performance for each class. In the last chapters, the results obtained by the analysis are presented and commented. The most important conclusions drawn after this paper are that in multi-server systems and priority serving, the first server dictates the behavior of the system, and the average delay time directly depends on the intensity of user arrivals and increases with its increase. When the classes are analyzed separately, it can be concluded that the classes with lower priorities have ever sharper increases in the delay time in the system which was also the expected result.
