1. 11. Improving Performance in Heterogeneous Networks: A Transport Layer Centered Approach

   Författare :Johan Garcia; Anna Brunström; Carsten Griwodz; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transport protocols; partial reliability; image transfer; transcoding; loss differentiation; fairness; wireless networks; network emulation; Computer science; Datavetenskap; Datavetenskap; Computer Science;

   Sammanfattning : The evolution of computer communications and the Internet has led to the emergence of a large number of communication technologies with widely different capabilities and characteristics. While this multitude of technologies provides a wide array of possibilities it also creates a complex and heterogeneous environment for higher-layer communication protocols. LÄS MER

3. 12. A Study of Partially Reliable Transport Protocols for Soft Real-Time Applications

   Författare :Karl-Johan Grinnemo; Anna Brunström; Bengt Ahlgren; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport protocol; internet; partial reliability; retransmission-based; real-time; simulation; taxonomy; survey; Computer Science; Datavetenskap;

   Sammanfattning : The profileration of multimedia applications, such as streaming video, teleconferencing, and interactive gaming has created a tremendous challenge for the traditional transport protocols of the Internet – UDP and TCP. Specifically, many multimedia applications are examples of soft real-time applications. LÄS MER

4. 13. Transport Services for Soft Real-Time Applications in IP Networks

   Författare :Karl-Johan Grinnemo; Anna Brunström; Reiner Ludwig; Philippe Owezarski; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transport protocol; congestion control; partial reliability; soft real-time; SCTP; failover; SIGTRAN; head-of-line blocking; Computer science; Datavetenskap; Datavetenskap; Computer Science;

   Sammanfattning : In recent years, Internet and IP technologies have made inroads into almost every communication market ranging from best-effort services such as email and Web, to soft real-time applications such as VoIP, IPTV, and video. However, providing a transport service over IP that meets the timeliness and availability requirements of soft real-time applications has turned out to be a complex task. LÄS MER

5. 14. 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. 15. 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
