Abstract

IMUNES network emulator is an excellent replacement for general purpose testbed, since it decreases the cost of equipment and management while increasing the scalability. However, IMUNES works on only one machine, so it has a limit in scalability, disallowing large-scale networks to be emulated. To circumvent this problem in this thesis we describe a distributed network simulator based on IMUNES. The distributed simulator is based on decentralized architecture, and thus avoiding the bottleneck. In addition, a novel algorithm for creating Internet-like topologies was designed, and the usability of two different graph partitioning algorithms was tested. The whole system was designed, implemented and evaluated. The results show that a decentralized version of distributed IMUNES is feasible. Moreover, the resulting system can be built in a scalable, transparent and secure manner while keeping the benefits of IMUNES.

Abstract (croatian)

Mrežni emulator IMUNES predstavlja izvrsnu zamjenu za testne mreže opće namjene. On reducira troškove opreme i upravljana mrežom, a povećava skalabilnost sustava. IMUNES radi samo na jednom računalu, što znači da za emulaciju velikih mreža nema dovoljno resursa. Kao rješenje tog problema u ovome radu opisan je distribuirana inačica IMUNES-a. Distribuirana inačica temelji se na decentraliziranoj arhitekturi izbjegavajući centralni element koji bi bio usko grlo sustava. Osim distribuirane inačice IMUNES-a u radu je opisan novi algoritam za stvaranja topologije Internet tipa, te su uspoređene performanse dva algoritma za particioniranje grafova. Cijeli sustav je dizajniran, implementiran te evaluiran. Rezultati pokazuju da je decentralizirana inačica IMUNES-a izvediva, te da je ona skalabilna, transparentna i sigurna dok čuva pozitivne karakteristike IMUNES-a.
