abstract = {Live migration is a technology that seamlessly relocates a virtualized service between physical hosts, which allows services to rapidly adapt to environmental changes. Despite the large amount of research, mainly aiming at minimizing the downtime, there is still a lack of understanding of its performance using the most common off-the-shelf virtualization technologies, namely docker containers and KVM. Understanding the barriers of live migration will give companies the knowledge on whether the migration is possible or not, when the migration needs to be triggered, how many resources the migration will use, and under which conditions the migration will be successful. Moreover, it helps to detect bottlenecks, and also to identify which parts of the migration need to be improved. Towards a better understanding of live migration, we build a testbed and use it to migrate a computation-intensive application with docker and KVM. We evaluate the service downtime, migration time, and network usage under different conditions. The results show that KVM outperforms docker in most of the scenarios, with some critical exceptions where only docker manages to perform migration.},

abstract = {Industry 4.0 is now much more than just a buzzword. However, with the advancement of automation through digitization and softwarization of dedicated hardware, applications are also becoming more susceptible to random hardware errors in the calculation. This cyber-physical demonstrator uses a robotic application to show the effects that even single bit flips can have in the real world due to hardware errors. Using the graphical user interface including the human machine interface, the audience can generate hardware errors in the form of bit flips and see their effects live on the robot. In this paper we will be showing a new technology, the SIListra Safety Transformer (SST), that makes it possible to detect those kind of random hardware errors, which can subsequently make safety-critical applications more reliable.},

That advanced feature of 5G networks will be demonstrated in the context of real-time video surveillance for public safety. Specifically, we demonstrate for the first time a practical deployment of Random Linear Network Coding (RLNC) with NFV and SDN technologies to improve video quality against packet loss due to congestion at the core network and signal impairment of lossy channels at network edges. The demonstration implements NFV and SDN applications on COTS devices to prove its flexibility and portability.},

abstract = {Future 5G mobile communication networks aim to provide many more use cases 

not only for people but also for connecting machines. Some of these 

applications, like VR/AR and automation, call for low latencies, which 

cannot be achieved by aggregated data centres. Also, for VR/AR, offloading 

of computation will be a key element to bring new experiences to mobile 

devices. In order to fulfil low latency, outsourcing of computation and 

mobility, the Mobile Edge Cloud (MEC) will play a key role in 5G 

networking. This demo shows an implementation of a VR game in an MEC with 

the capability to move game servers across the world without service 

interruption},
