The PhD defence will be partially digital, in Kristen Nygaards sal (5370), Ole-Johan Dahls hus and streamed directly using Zoom. The host of the session will moderate the technicalities while the chair of the defence will moderate the disputation.
Ex auditorio questions: the chair of the defence will invite the attending audience at Kristen Nygaards sal to ask ex auditorio questions.

"Software Defined Networking (SDN) and Network Function Virtualization (NFV)"
Main research findings
- Today’s Internet is facing significant challenges as the number of the connected
devices, applications, and the amount of traffic grow tremendously. The
challenges are particularly related to the insufficient security and
performance, complexity in providing mobility and multihoming, and the inability
to easily accommodate new protocols and technologies.
Over the last two decades, there has been considerable effort by the networking
research community to evolve or redesign the Internet architecture. Unlike
evolutionary approaches, "clean-slate" designs follow a more drastic path to
overcome the fundamental architecture limitations of the current
Internet. However, such solutions are facing large deployment barriers, mainly
because the Internet does not provide architectural modularity. Among the
clean-slate initiatives, RINA—the Recursive InterNetwork Architecture—is
perhaps the most drastic one which attempts to offer a general solution with a
complete networking theory.
This dissertation tackles the deployment challenges and investigates several
strategies to deploy a new clean-slate architecture such as RINA in the current
networks. These strategies are: (1) direct usage with a fall-back, (2) adapting
the Application Programming Interface (API), and (3) a gateway to translate
between protocols. Real-life experiments of the first congestion control
approach that is suitable for a flexible recursive architecture show the
performance improvement that can be attained with these strategies.
