  4. 3. 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

  5. 4. A Study of Partially Reliable Transport Protocols for Soft Real-Time Applications

    Författare :Karl-Johan Grinnemo; Anna Brunström; Bengt Ahlgren; Karlstads universitet; []
