Abstract

Programski upravljanje komunikacijske mreže imaju odvojen upravljački sloj od sloja prosljeđivanja podataka. Takva arhitektura omogućuje lakše razvijanje i testiranje novih mrežnih aplikacija ili protokola za komunikaciju. Za komunikaciju između navedenih slojeva koristi se protokol OpenFlow. Postoje reaktivni i proaktivni način pronalaženja najkraćeg puta prosljeđivanja. U ovome radu je implementiran i analiziran, alatom za analizu mrežnog prometa Wireshark, reaktivan način ifwd koji je zasnovan na namjerama. Namjere su smjernice temeljene na određenim pravilima. Reaktivan način rada u ovome slučaju je da ako dođe do kvara na poveznici, izračuna se novi put te ugrađuje preko namjera.

Abstract (english)

Software Defined Networks (abbr. SDN) has a separated control layer from the data transmission layer. That kind of architecture enables easier development and testing of new network applications or communication protocols. OpenFlow protocol is used to communicate between these layers. There is a reactive and proactive way of finding the shortest forwarding path. In this paper, a Intent-based, ifwd reactive method was implemented and analyzed with Wireshark network analysis tool. Intents are guidelines based on certain rules. The reactive way in this case is that if a link is down then a new path is calculated and new intent is installed.
