1. 1. Improving the Timeliness of SCTP Message Transfers

   Författare :Per Hurtig; Anna Brunstrom; Johan Garcia; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SCTP; transport protocols; network emulation; loss recovery; Nagle algorithm; Computer science; Datavetenskap; Materials Engineering; Materialteknik;

   Sammanfattning : Due to the cheap and flexible framework that the underlying IP-technology of the internet provides, IP-networks are becoming popular in more and more contexts. For instance, telecommunication operators have started to replace the fixed legacy telephony networks with IP-networks. LÄS MER

3. 2. Transport-Layer Performance for Applications and Technologies of the Future Internet

   Författare :Per Hurtig; Anna Brunström; Saverio Mascolo; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TCP; SCTP; transport protocols; loss recovery; packet reordering; congestion control; performance evaluation; Computer Science; Datavetenskap;

   Sammanfattning : To provide Internet applications with good performance, the transport protocol TCP is designed to optimize the throughput of data transfers. Today, however, more and more applications rely on low latency rather than throughput. Such applications can be referred to as data-limited and are not appropriately supported by TCP. LÄS MER

4. 3. Improving Development of Communication Software in Industrial Control Systems using Simulation

   Författare :Niclas Ericsson; Mats Björkman; Johan Åkerberg; Thomas Lennvall; Per Hurtig; RISE; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Sciences; Datavetenskap datalogi ;

   Sammanfattning : In the industrial domain customers expect a product longevity of 10-20 years, with high reliability and availability. Since industrial distributed control systems often are safety critical, aspects such as determinism, low latency and jitter are crucial. LÄS MER

5. 4. Achieving Low Latency and High Throughput over Cellular Internet Connections

   Författare :Habtegebreil Kassaye Haile; Anna Brunström; Karl-Johan Grinnemo; Per Hurtig; Simone Ferlin; Markku Kojo; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QUIC; BBR; Copa; TCP; Congestion control; Throughput; Queuing Delay; Performance Evaluation; 4G; 5G; Kalman Filter; Computer Science; Datavetenskap;

   Sammanfattning : The continuous increase in the number and type of Internet services and their requirements for improved QoS has motivated the steady evolution  of cellular networks towards the current fifth generation (5G) systems. However, updating the network to 5G is insufficient to satisfy application requirements since performance limitations can also exist in the transport used by the applications. LÄS MER

7. 5. 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
