Abstract
The doctoral thesis entitled “Availability modelling and evaluation of optical cross-connect implemented by architecture on demand” presents the results of investigation on the influence of Architecture on Demand (AoD) concept on availability of optical cross-connect nodes and related optical networks. The main challenge was to find out the trade-off between negative impact of AoD on node availability / power consumption / cost (APC) due to increased complexity of added switching elements, and benefits on APC arising from AoD self-healing capability and smart application of redundancy released in AoD. The goal was to prove the hypothesis that cross-connect structures implemented by AoD are cost-effective and improve not only functionality but also optical node / network availability.Extended research on the impact of AoD optical cross-connect nodes to entire network availability, cost and power consumption was provided. Analysis on real architectures in order to assess the trade-off between the benefits and shortcomings of AoD applications was carried out. Methodology is based on creating new availability models of optical nodes and novel algorithms for smart applications of AoD advantages in improvement of network availability. In the availability analysis Monte Carlo failure simulation were used and analytical approaches where appropriate.
Abstract (croatian)
Doktorski rad pod naslovom “Modeliranje i proračun raspoloživosti optičkih prospojnika implementiranih s pomoću arhitekture na zahtjev” predstavlja rezultate istraživanja utjecaja koncepta arhitekture na zahtjev (AoD) na raspoloživost optičkih prospojnika te time i pripadnih optičkih mreža. Glavni izazov bio je odvagati negativni utjecaj AoD-a na raspoloživost, potrošnju energije i cijenu (APC) čvora, radi porasta složenosti sustava uvođenjem dodanih komutacijskih elemenata, i dobitak za APC koji proizlazi iz svojstva samoobnavljanja AoD-a i pametne primjene redundancije oslobođene njegovom primjenom. Cilj je bio da se dokaže hipoteza da su strukture prospojnika implementiranih pomoću AoD-a isplative te da poboljšavaju ne samo funcionalnost već i raspoloživost optičkih čvorova i mreže. Provedena su opsežna istraživanja o utjecaju AoD optičkih prospojnika na raspoloživost mreže, cijenu mreže i potrošnju energije. Analizirane su realne arhitekture optičkih čvorova da bi se ocijenile prednosti i nedostatci primjene AoD-a. Metodologija se temelji na kreiranju novih modela raspoloživosti optičkih čvorova i novih algoritama za pametnu primjenu prednosti koje u poboljšanju raspoloživosti pruža koncept AoD. U analizi raspoloživosti korištene su simulacije kvarova Monte Carlo i analitičke metode tamo gdje je to bilo moguće.
