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

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

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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.
