Abstract

 

The ossification of networks has long been considered a major impediment for the evolution of networks. One popular approach to tackle this challenge is to replace fixed control mechanisms in network devices by remote control facilitated by remote control, implementable in arbitrary software modules. This concept - commonly referred to as Software Defined Networking - has attracted considerable interest from both academia and industry over the past ten years. It promises great flexibility but still has to prove its practical feasibility.

Another trend is to allow the execution of software in network devices itself. Leveraging general trends like distributed cloud computing and micro-services, the idea is to realise network-specific functions (e.g., firewalls, signal processing in mobile networks) in software, possibly implemented using lean mechanisms like containers, and deploy them at suitable places.

These topics will be introduced by an overview talk and detailed talks on algorithmic and system aspects of NFV. We shall also consider architectural challenges, investigating whether so-far diverse fields like micro-services, NFV and DCC as well as SDN should be integrated more tightly in the future.

Prof. Holger Karl obtained his PhD in cluster computing in 1999 from Humboldt University of Berlin. Since 2000, works in networking, first as a post-doc at Technical University Berlin and since 2004 as chair of Computer Networks at Paderborn University. His current research interest comprise Internet and data centre architectures, SDN and NFV, as well as wireless communication, in particular, industrial wireless applications.
