• Accuracy vs. Cost Trade-off for Machine Learning Based QoE Estimation in 5G Networks 

      Schwarzmann, Susanna; Marquezan, Clarissa Cassales; Trivisonno, Riccardo; Nakajima, Shinichi; Zinner, Thomas (Chapter, 2020)
      Since their first release, 5G systems have been enhanced with Network Data Analytics Functionalities (NWDAF) as well as with the ability to interact with 3rd parties' Application Functions (AFs). Such capabilities enable ...
    • Bandwidth Prediction Schemes for Defining Bitrate Levels in SDN-enabled Adaptive Streaming 

      Alissa, Ali; Bentaleb, Abdelhak; Barakabitze, Alcardo; Ghita, Bogdan V.; Zinner, Thomas (Chapter, 2019)
      The majority of Internet video traffic today is delivered via HTTP Adaptive Streaming (HAS). Recent studies concluded that pure client-driven HAS adaptation is likely to be sub-optimal, given clients adjust quality based ...
    • Comparing fixed and variable segment durations for adaptive video streaming: a holistic analysis 

      Schwarzmann, Susanna; Hainke, Nick; Zinner, Thomas; Sieber, Christian; Robitza, Werner; Raake, Alexander (Chapter, 2020)
      HTTP Adaptive Streaming (HAS) is the de-facto standard for video delivery over the Internet. It enables dynamic adaptation of video quality by splitting a video into small segments and providing multiple quality levels per ...
    • 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 ...
    • P4CONSIST: Towards Consistent P4 SDNs 

      Shukla, Apoorv; Fathalli, Seifeddine; Zinner, Thomas; Hecker, Artur; Schmid, Stefan (Peer reviewed; Journal article, 2020)
      The prevailing wisdom is that a software-defined network (SDN) operates under the premise that the logically centralized control plane has an accurate representation of the actual data plane state. Unfortunately, bugs, ...
    • Using informed access network selection to improve HTTP adaptive streaming performance 

      Enghardt, Theresa; Zinner, Thomas; Feldmann, Anja (Chapter, 2020)
      As end-user devices often have multiple access networks available, choosing the most suitable network can help to improve application performance and user experience. However, selecting the best access network for HTTP ...
