• Monitoring and Analyzing a Game Server Scenario 

      Jelmert, Stian Opsahl (Master thesis, 2008)
      Today, most literature about services in system administration is about conventional services like email servers. How could one monitor and analyze a scenario where the service in question is a game server? As these two ...

      With the exponential growth in cloud computing, the steadily increasing amount of power consumption due to the use of physical and virtual machines is becoming a serious challenge. In this context, we report a study on ...
    • Orchestrating Resource Allocation for Interactivevs. Batch Services using a Hybrid Controller 

      Ahmad, Bilal; Yazidi, Anis; Haugerud, Hårek; Farokhi, Soodeh (Chapter; Peer reviewed, 2017)
      Cloud service providers are trying to reduce their operating costs while offering their services with a higher quality via resorting to the concept of elasticity. However, the vast majority of related work focuses solely ...
    • Passive traffic characterization and analysis in heterogeneous IP networks 

      Thorkildssen, Håvard Wik (Master thesis, 2005)
      In this thesis we revisit a handful of well-known experiments, using modern tools, to see if results yielded from earlier experiments are valid for today’s heterogeneous networks. The traffic properties we look at are ...
    • Poster: QoE-Based Analysis of Real-Time Adaptive 360-Degree Video Streaming 

      Midoglu, Cise; Klausen, Magnus; Alay Erduran, Özgü; Yazidi, Anis; Haugerud, Hårek; Griwodz, Carsten (S3: Wireless of the Students, by the Students, for the Students;S3'19: Proceedings of the 2019 on Wireless of the Students, by the Students, and for the Students Workshop, Chapter; Conference object; Peer reviewed, 2019-10)
      We propose a QoE-based analysis approach for real-time adaptive 360-degree video streaming measurements, focusing on the correlation between objective video metrics and subjective end-user scores.
    • Recovering Request Patterns to a CPU Processor from Observed CPU Consumption Data 

      Hammer, Hugo Lewi; Yazidi, Anis; Bratterud, Alfred; Haugerud, Hårek; Feng, Boning (Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering;188(1), Journal article; Peer reviewed, 2016)
      Statistical queuing models are popular to analyze a computer systems ability to process different types requests. A common strategy is to run stress tests by sending artificial requests to the system. The rate ...
