   Sammanfattning : Modern virtualized Data Centers (DCs) require efficient management techniques to guarantee high quality services while reducing their economical cost. The ability to live migrate virtual instances, e.g. LÄS MER

4. 23. Network Management for Dynamic and Heterogeneous Wireless Sensor Networks

   Författare :Shunmuga Priyan Selvaraju; Mats Björkman; Ali Balador; Hossein Fotouhi; Maryam Vahabi; Cicek Cavdar; Mälardalens universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

   Sammanfattning : Wireless Sensor Networks (WSNs) are interconnections of spatially distributed sensor nodes with low-power wireless communication. In comparison with traditional wireless networks, WSNs provide novel features in network architecture, which are known as low-cost networking, rapid formation, widespread arrangement, self-organisation, and ease of deployment.

5. 24. 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

7. 25. Towards Secure Multipath TCP Communication

   Författare :Zeeshan Afzal; Stefan Lindskog; Anna Brunstrom; Stefan Axelsson; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; network security; MPTCP; TCP; IDS; snort; edit-distance; Computer Science; Datavetenskap;

   Sammanfattning : The evolution in networking coupled with an increasing demand to improve user experience has led to different proposals to extend the standard TCP. Multipath TCP (MPTCP) is one such extension that has the potential to overcome few inherent limitations in the standard TCP. LÄS MER
