Abstract

U modernom svijetu, zbog obavljanja poslovnih ili privatnih obaveza, ključno je ostati stalno povezan na Internet. U tu svrhu se osiguravaju redundantne (rezervne) veze kako bi korisnici i u slučaju pada primarne veze ili uređaja ostali povezani. U radu je analizirana problematika koja se javlja prilikom pogrešne implementacije redundantnih veza, a to je nastanak petlji drugog sloja koje dovode do stanja mreže pod nazivom broadcast storm. Simulacijom je prikazano zašto je važno poznavanje te problematike i do čega ona dovodi te u konačnici kako je spriječiti. Kako bi se mogao spriječiti broadcast storm, važno je razumjeti njezin nastanak. Sukladno tome, opisano je broadcast odašiljanje, na koji način radi preklopnik te proces nastajanja petlji drugog sloja koje dovode do broadcast storm-a. Na kraju, razrađeni su algoritmi i protokoli u svrhu njezinog sprječavanja.

Abstract (english)

In the modern world, due to performing business or private obligations it is very important to constantly stay connected to the internet. For that purpose, redundant (backup) links are provided so that users remain connected even in a case of failure of primary link or device. This paper analyzes the problem that occurs in the event of wrong implementation of redundant links, and that is formation of layer two loops that lead to broadcast storm. The simulation shows why it is important to understand this problem, what it leads to and ultimately how to prevent it. In order to prevent a broadcast storm, it is important to understand its occurrence. Accordingly, broadcasting is described, how the switch works and the process of forming layer two loops. Finally, algorithms and protocols that are developed for this purpose are elaborated in this paper.
