  1. 16. Improving the Adaptability of the End-host : Service-aware Network Stack Tuning

    Författare :Alexander Rabitsch; Anna Brunström; Per Hurtig; Stefan Alfredsson; Michael Welzl; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transport layer; 5G; transport services; mobile broadband; network slicing; latency; availability; service optimization; multi-connectivity; Computer Science; Datavetenskap;

    Sammanfattning : The Internet of today is very different from how it used to be. Modern networked applications are becoming increasingly diverse. Consequently, a variety of requirements must be met by the network. Efforts to make the underlying mechanisms of the Internet more flexible have therefore been made to adapt to this diversification.
