Abstract

Ovaj rad podijeljen je u dvije glavne cjeline. Prva i opsežnija cjelina ovog rada orijentirana je na predstavljanje višeuslužnih mreža i koncepta kvalitete usluge u takvim mrežama. Također, iznesen je problem heterogenosti mreža koji otežava osiguranje kvalitete usluge od kraja do kraja te su prikazani neki od mehanizama za rješavanje tog problema. U drugoj cjelini rada provedena je analiza vremena čekanja paketa u čvoru višeuslužne mreže ovisno o njihovoj duljini, kapacitetu kanala i metodi dodjele kapaciteta. Analiza je sprovedena pomoću simulacije u alatu Microsoft Excel gdje su simulirana 3 čvora povezana sa različitim kapacitetima linkova nakon čega je bilo izračunato vrijeme čekanja pojedinog paketa. Rezultat simulacije su grafovi iz kojih su izneseni zaključci za odabir metode dodjele kapaciteta.

Abstract (english)

This thesis is separated in two main units. The first and the wider part of this thesis is oriented on presentation multiservice networks and concept of quality of service in such networks. Also, the problem of heterogeneity networks that hinders the end-to-end quality of service and some of the mechanisms to prevent this problem are presented. In the second part of this thesis an analysis of package waiting time in the multi-service network has been conducted, depending on the average package length, capacity of the link and method for capacity allocation. The analysis was carried out using Excell for simulation three nodes which are associated with different connection capacities after which the waiting time of particular packet was calculated. The result of the simulation are the graphs from which the conclusion of the selection of the capacity allocation method are presented.
