Abstract

Uvođenje ISDN-a u hrvatsku telefonsku mrežu osnovna je tema ovoga rada. Opisana je telefonska mreža kao osnova za ISDN te aspekti ISDN-a. Navedeni su primjeri primjene ISDN usluga te koju je ulogu imao ISDN u povezivanju Interneta i javne telefonske mreže. Dani su kvalitativni prikazi ukupnog prometa i posebno prometa prema Internetu na pristupnim i tranzitnim centralama. Kao slijedeći korak u razvoju telekomunikacijske mreže, predstavljena je konvergencija dviju mreža i usluga: telefonske i podatkovne. Predstavljen je mogući koncept mreže nove generacije. Kao nezaobilazna funkcija u mreži opisano je usmjeravanje prometa te moguća unaprijeđenja prema dinamičkom i adaptivnom usmjeravanju. Na već izrađenom modelu za testiranje metoda usmjeravanja (LAG) napravljeni su eksperimenti koji pokazuju usporedne rezultate simulacije fiksnog usmjeravanja i usmjeravanja na osnovu automata sa svojstvom učenja.

Abstract (english)

The basic subject of this paper is the implementation of ISDN to the Croatian PSTN network. Public Switched Telephony Network is described as a basis for ISDN. The implementation of ISDN services is presented through all relevant aspects. Further, the examples of ISDN usage and the impact of ISDN on connection of Internet and PSTN are mentioned. Description of the network and ISDN implementation are followed by qualitative presentations of the total and Internet traffic on the local and transit exchanges. The next step in network development is presented through the convergence of the PSTN and data networks and services. Possible concept of the next generation network is described. As traffic routing is an important function in the network, its improvement towards dynamic and adaptive routing is presented. Simulations of fixed routing and the routing based on learning automata are performed on the already designed mogul (LAG). The results of simulations that are presented serve for the comparison of routing methods.
