With Network Function Virtualization the elements of the chain can be provisioned in virtual environments on any COTS hardware. This introduces the question of where to position the individual network functions within the virtualization environment. This problem of network function placement has been studied in theory as an optimization problem on a graph. However it is challenging to apply theoretical work on practical deployments. In this paper, we perform a measurement campaign to study the delay introduced by Service Function Chaining. We propose placement heuristics and evaluate the performance on OpenStack. With the proposed heuristics, the service delay can be reduced by more than 20%. We measured the overhead introduced by a network function implemented in user space. The processing delay in user space can be twice as much as the same function in kernel space. More interestingly, we identified a service interruption of more than 1 second after activation of the chain.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

To overcome those disruptive changes, future communication systems are substituting specialized hardware with generic hardware boxes and the softwarization paradigm. Furthermore, this approach allows for quick deployment of new services, which was known to cloud service already. In this paper, we will introduce the most prominent candidates for softwarization such as software defined networking (SDN) and network function virtualization (NFV) and explain the importance of those technologies for the upcoming 5G communication system and tactile internet applications realizing novel mobile edge computing, storage, and networking solutions. Specifically, we will discuss use cases of SDN/NFV such as network coding as a service, and ultra-reliable distributed edge caching. Finally, we will describe our holistic testbed at 5G Lab Germany as a fundamental step towards creating an experiment infrastructure that anticipates the 5G communication systems and tactile internet applications.}, keywords = {}, pubstate = {published}, tppubtype = {article} }
