Abstract

U radu je prvo dan osnovni pregled glavnih značajki programski upravljanih mreža, odnosno SDN mreža. Nadalje, dan je kratak pregled metoda za vizualizaciju podataka o komunikacijskim mrežama te su istaknuti moderni izazovi vizualizacije, kako za komunikacijske mreže općenito, tako i za one zasnovane na konceptu SDN.
Opisan je model web-aplikacije za vizualizaciju topologije SDN mreža i puteva prosljeđivanja paketa kroz njih, zajedno s glavnim funkcijskim zahtjevima. Detaljno je predstavljena sama programska izvedba web-aplikacije, kroz implementacijske detalje, funkcije koje se koriste i način komunikacije aplikacije sa SDN upravljačkim uređajem OpenDaylight. Na kraju su ilustrirane mogućnosti web-aplikacije na nekoliko primjera vizualizacije puteva prosljeđivanja kroz emuliranu SDN mrežu.

Abstract (english)

This thesis starts by giving a basic summary of main features of software-defined networks, that is, SDN networks. Furthermore, it gives a short overview of data-visualization methods used in traditional communication networks, as well as pointing out the modern challenges of that sort of visualization, as for communication networks in general, as for those who are based on SDN concept.
In continuation, a model of web-application for SDN-network topology and forwarding paths is given, together with its main functional demands. A detailed overview of software implementation is given, mentioning implementation details, used functions and ways of communication between application and SDN controller. In the end, there is a look at application's visualization prowess by using an emulated SDN network to visualize forwarding paths.
