Abstract

Završni rad se bavi detaljnom analizom i obradom sustava usmjeravanja, interoperabilnosti te protokolima VoIP tehnologije. Usmjeravanje u telekomunikacijskoj mreži predstavlja način prosljeđivanja paketa od izvorišta do krajnjeg odredišta. VoIP (eng. Voice over Internet Protocol) predstavlja proces digitaliziranja i slanja glasovnih podataka preko IP mreža. Algoritmi usmjeravanja izgrađuju tablice usmjeravanja i u njih pohranjuju podatke na temelju kojih se određuje najbolja ruta prosljeđivanja do krajnjeg odredišta. Konvergencija je nužna karakteristika svakog algoritma usmjeravanja, predstavlja postupak gdje se svi usmjerivači slažu oko najbolje rute za podatkovni prijenos. Usmjerivači razmjenjuju ažurirajuće poruke koje širenjem kroz mrežu potiču ponovni proračun ruta koje postupno konvergiraju u optimalan raspored. Proces usmjeravanja se odvija u mrežnom sloju OSI (eng. Open Systems InterconnectionI) referentnog modela. Za uspostavu podatkovne komunikacije VoIP tehnologija koristi protokole koji se implementiraju u aplikacijskom sloju za prijenos zvuka i pokretnih slika. VoIP sustav ima integraciju sa javnom telefonskom mrežom (PSTN). Rad između VoIP i PSTN mreže predstavlja uspostavljanje poziva u telefonskoj mreži te završetak na Internet mreži i obrnuto.

Abstract (english)

This paper discusses detailed analysis and processing of routing system, interoperability and protocols for VoIP (Voice over Internet Protocol) technology. VoIP is defined as process of digitalizing and sending voice data through IP network. Routing in telecommunication network represents a method of forwarding packets from source to endpoint and is no less important in real-time communication network such as VoIP. Routing algorithms play a central role in generating a routing table for storing data that fundamental for choosing the optimal route. Convergence is necessary characteristic of updating process of routing table which represents a state where a set of routers reached a consensus on topology information. Therefore, routers constantly exchange update information which, by spreading across the network, continuously encourage estimation of routes until an optimal routing schedule is reached. Routing is carried on a network layer of OSI reference model. Another important topic from a technological point of view and discussed in this paper is VoIP-PSTN interoperability. This is because This, in turn, enables establishing a call that originates in PSTN and ends in Internet network and vice versa.
