      The Softwarization of networks is enabled by the SDN (Software-Defined Networking), NV (Network Virtualization), and NFV (Network Function Virtualization) paradigms, and offers many advantages for network operators, service ...

    • Guest Editors' Introduction: Special Section on Smart Management of Future Softwarized Networks 

      Schembra, Giovanni; Kellerer, Wolfgang; Jacquenet, Christian; Kamiyama, Noriaki; Martini, Barbara; Pasquini, Rafael; Pezaros, Dimitrios; Riggio, Roberto; Zhang, Hongke; Zhani, Mohamed Faten; Zinner, Thomas (Peer reviewed; Journal article, 2022)
      Network softwarization is one of the key enablers of the future Internet evolution, also supporting the road from the fifth generation (5G) to the next-generation communication systems, namely 6G, with their main objective ...

    • Implementation of BOLA and Comparison with Other Adaptive Bitrate (ABR) Mechanisms in the OMNeT++ Simulation Platform 

      Edvardsen, Kristian Zunder (Master thesis, 2023)
      I dag er vi være vitne til en økning i videostreaming på internett, muliggjort av en rekke strømningsteknologier som er tilgjengelige over hele verden. En av de mest utbredte teknikkene som brukes for videostreaming er ...

    • Linking QoE and Performance Models for DASH-based Video Streaming 

      Schwarzmann, Susanna; Zinner, Thomas (Chapter, 2020)
      HTTP Adaptive Streaming (HAS) is the de-facto standard for video delivery over the Internet. Splitting the video clip into small segments and providing multiple quality levels per segment allows the client to dynamically ...

    • ML-based QoE Estimation in 5G Networks Using Different Regression Techniques 

      Schwarzmann, Susanna; Marquezan, Clarissa Cassales; Trivisonno, Riccardo; Nakajima, Shinichi; Barriac, Vincent; Zinner, Thomas (Journal article; Peer reviewed, 2022)
