Abstract

Računalne mreže su se razvile zbog novih trendova i zahtjeva korisnika za što
bržom uspostavom i isporukom usluga. Nefleksibilnost arhitekture računalnih mreža
predstavlja izazov razvijateljima jer se njihovi eksperimenti ne mogu ocijeniti u
stvarnim mrežama. Softverski definirana mreža (SDN) i OpenFlow arhitektura
omogućuju način implementacije programabilnih mrežnih arhitektura koje se mogu
implementirati postepeno u već postojeću mrežu. Kontrola mreže je na vanjskom
uređaju u obliku software-a odvojena od prosljeđivanja paketa i ima mogućnost
direktnog programiranja. SDN omogućuje dinamičku prilagodbu mrežnog okruženja
trenutnim aplikativnim zahtjevima ili potrebama korisnika te znatno pojednostavljuje
upravljanje i povećava skalabilnost mreže. U ovom radu su analizirane
funkcionalnosti i karakteristike softverski definiranih mreža i na temelju usporedbe s
konvencionalnom mrežom utvrđene su bitne razlike, prednosti i nedostaci te koliko
SDN utječe na samo poslovanje jedne organizacije (tvrtke).

Abstract (english)

The new trends and users' demands for fastest setting up and delivering of
new services are the main reasons for computer networks being developed. The
inflexibility in architecture of computer networks represents a challenge for
developers due to the fact that their experiments can not be verified in real networks.
Software Defined Networks (SDN) and the OpenFlow architecture allow
implementation of programmable networks' architectures, which can be gradually
deployed in already existing networks. The network control is on an external device
as a kind of software program (Controller). It is separated from the packet forwarding
(Switch), having the possibility of being directly programmed. SDN enables dynamic
adaptation of networks' environments to the current applications' requests or users'
demands, making the network control easier and at the same time increasing its
scalability. In this thesis, the functionality and characteristics of software defined
networks have been analysed and due to the comparison with conventional
networks, the main differences, advantages and drawbacks have been
determined as well as the answer to the question: How much software defined
networks can influence the core business of an organisation?
