Abstract

Programski upravljana mreža predstavlja moderan pristup upravljanja mrežnim uređajima, razdvajajući njihove podatkovne i kontrolne funkcije. Kontrolne funkcije preuzima udaljeni upravljački uređaj, a kontrolne veze između upravljačkog i mrežnih uređaja postaju nužne za podešavanje rada mreže. U ovom radu je izveden i demonstriran mehanizam zaštite kontrolnih veza pomoću proaktivno postavljenih rezervnih puteva između upravljačkog uređaja ONOS i mrežnih uređaja, dok se kontrolne veze zasnivaju na specifikaciji OpenFlow. Pokazano je da se, uslijed kvara na primarnom putu, aktivacijom rezervnog puta omogućuje neometana razmjena kontrolnih poruka, a samim time i ispravan rad mreže.

Abstract (english)

Software-defined network represents a modern approach to managing network devices, by splitting their data and control functions. Control functions are taken over by a remote controller, while control connections between a controller and network devices become necessary for configuration of the network operation. In this thesis, a protection mechanism for control connections is implemented and demonstrated, by proactively setting up reserve paths between the ONOS controller and network devices, while control connections are based on the OpenFlow specification. It is shown that, due to a failure on primary path, activation of a reserve path allows uninterrupted exchange of control messages and, thus, the correct operation of the network.
