    • A Survey on Network Resiliency Methodologies against Weather-based Disruptions 

      Kmiecik, Wojciech; Rak, Jacek; Medeiros, Carmo; Heegaard, Poul Einar; Mas Machuca, Carmen; André, Joao; Jorge, Luisa; Musumeci, Francesco; Voyiatzis, Artemios; Pasic, Alija; Tornatore, Massimo; Travanca, Rui; Furdek, Marija; Hmaity, Ali; Simpson, Steven; Babarczi, Peter; Martins, Lucia; Følstad, Eirik Larsen; Braun, Torsten (Chapter, 2016)
      Due to the increasing dependence on network ser- vices of our society, research has recently been concentrating on enhancing traditional protection strategies to withstand large- scale failures, as in case of disaster ...

    • An Empirical Study of Software Reliability in SDN Controllers 

      Vizarreta, Petra; Trivedi, Kishor; Helvik, Bjarne Emil; Heegaard, Poul Einar; Kellerer, Wolfgang; Mas Machuca, Carmen (Chapter, 2017)
      Software Defined Networking (SDN) exposes critical networking decisions, such as traffic routing or enforcement of the critical security policies, to a software entity known as the SDN controller. Controller software, as ...

    • Assessing the maturity of SDN controllers with software reliability growth models 

      Vizarreta, Petra; Trivedi, Kishor; Helvik, Bjarne Emil; Heegaard, Poul Einar; Blenk, Andreas; Kellerer, Wolfgang; Mas Machuca, Carmen (Journal article; Peer reviewed, 2018)
      In software defined networking (SDN), critical control plane functions are offloaded to a software entity known as the SDN controller. Today's SDN controllers are complex software systems, owing to heterogeneity of networks ...

    • Cost comparison studies of different network platforms: OpEx modeling and analysis 

      Moe, Øyvind Solberg (Master thesis, 2007)
      The importance of Operational Expenditures (OpEx) on the overall network cost has been shown in recent studies. This master thesis is part of a series of techno economical studies focused on the evaluation of OpEx and the ...

    • Network Sovereignty: A Novel Metric and Its Application on Network Design 

      Janardhanan, Shakthivelu; Samonaki, Maria; Heegaard, Poul Einar; Kellerer, Wolfgang; Mas Machuca, Carmen (Journal article; Peer reviewed, 2024)
      Most network planning problems in the literature consider metrics, such as cost, availability, and other technology-aware attributes. However, network operators now face new challenges in designing their networks to minimize ...

    • Technology-related Disasters: A Survey towards Disaster-resilient Software Defined Networks 

      Mas Machuca, Carmen; Secci, Stefano; Vizerrata, Petra; Kuipers, Fernando; Gouglidis, Antonios; Hutchison, David; Jouet, Simon; Pezaros, Dimitrios; Elmokashif, Ahmed; Heegaard, Poul Einar; Ristov, Sasko (Chapter, 2016)
      Resilience against disaster scenarios is essential to network operators, not only because of the potential economic impact of a disaster but also because communication networks form the basis of crisis management. COST ...
