  2. 1. Bufferbloat and Beyond : Removing Performance Barriers in Real-World Networks

    Author : Toke Høiland-Jørgensen; Anna Brunström; Per Hurtig; Luca Muscariello; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bufferbloat; AQM; WiFi; XDP; TSQ; Flent; network measurement; performance evaluation; fairness; queueing; programmable packet processing; Computer Science; Datavetenskap;

    Abstract : The topic of this thesis is the performance of computer networks. While network performance has generally improved with time, over the last several years we have seen examples of performance barriers limiting network performance. In this work we explore such performance barriers and look for solutions. READ MORE

  4. 2. On the Bleeding Edge : Debloating Internet Access Networks

    Author : Toke Høiland-Jørgensen; Anna Brunstrom; Per Hurtig; Michael Welzl; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bufferbloat; WiFi; AQM; queueing; network measurement; performance evaluation; fairness; Computer Science; Datavetenskap;

    Abstract : As ever more devices are connected to the internet, and applications turn ever more interactive, it becomes more important that the network can be counted on to respond reliably and without unnecessary delay. However, this is far from always the case today, as there can be many potential sources of unnecessary delay. READ MORE

  5. 3. Aspects of Quality : Using Quality Measurements to Improve Computer Network Performance

    Author : Pehr Söderman; Peter Sjödin; Markus Hidell; Karl-Johan Grinnemo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; Datalogi;

    Abstract : As computer networks grow in complexity, measuring the performance becomes a challenge. Intrinsic properties of the networks capability to transport data, such as bandwidth, latency, loss, and error rate are not always enough to provide a clear picture of how well the network can satisfy the users' expectations.

  6. 4. Secure and scalable roaming support in heterogeneous access networks

    Author : Daniel Granlund; Mika Ylianttila; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pervasive Mobile Computing; Distribuerade datorsystem;

    Abstract : Mobility support for users connecting to the Internet is an increasing trend. Different types of access networks like WiFi, CDMA, and UMTS are available, creating a heterogeneous access network environment. In the Internet today, there are a number of providers of various sizes supporting different technologies. READ MORE

  7. 5. Performance Analysis in Wireless HetNets: Traffic, Energy, and Secrecy Considerations

    Author : Georgios Smpokos; Nikolaos Pappas; Vangelis Angelakis; Qinghua Wang; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : To this day, most of the communication networks are characterized by a "monolithic" operating approach. Network elements are configured and operate without any reconfiguration for long time periods. Softwarization, whereby dedicated elements are being replaced by more general-purpose devices, has been lately challenging this existing approach. READ MORE
