Abstract

U današnje vrijeme zbog povećanih prometnih zahtjeva dolazi do potrebe za unaprjeđenjem prospojnih čvorova. Arhitektura na zahtjev je tehnologija koja omogućuje efikasno i fleksibilno prospajanje. Ovaj rad bavi se mehanizmima zaštite u mreži čiji su čvorovi izvedeni pomoću arhitekture na zahtjev. Implementirani algoritmi pronalaze radne i zaštitne valne puteve te pokušavaju ostvariti zaštitu na razini čvora pomoću prospajanja na razini niti, što je jedna od karakteristika arhitekture na zahtjev. Za simuliranje rada mreže korištena je Monte Carlo simulacija.

Abstract (english)

Nowadays, due to the increase of traffic demands there is need for improvement of optical cross-connect nodes. Architecture on Demand is technology that can provide efficient and flexible cross-connecting. This paper focuses on protection mechanisms in network with nodes implemented by Architecture on Demand. Implemented algorithms are designed to find both working and backup lightpaths, which enable protection on the network level. On the other hand, implented algorithms are trying to enable fibre switching, which is one of the main characteristics of Architecture on Demand. Fibre switching provides protection on the node level. Simulations were conducted by Monte Carlo procedure.
