Oftentimes, the timely provisioning of access to and the implementation of affordable care are drivers behind tele-healthcare initiatives. Tele-healthcare has already garnered significant momentum in research and implementations in the years preceding the worldwide challenge of 2020, supported by the emerging capabilities of communication networks. The Tactile Internet (TI) with human-in-the-loop is one of those developments, leading to the democratization of skills and expertise that will significantly impact the long-term developments of the provisioning of care. However, significant challenges remain that require today\’s communication networks to adapt to support the ultra-low latency required. The resulting latency challenge necessitates trans-disciplinary research efforts combining psychophysiological as well as technological solutions to achieve one millisecond and below round-trip times. The objective of this paper is to provide an overview of the benefits enabled by solving this network latency reduction challenge by employing state-of-the-art Time-Sensitive Networking (TSN) devices in a testbed, realizing the service differentiation required for the multi-modal human-machine interface. With completely new types of services and use cases resulting from the TI, we describe the potential impacts on remote surgery and remote rehabilitation as examples, with a focus on the future of tele-healthcare in rural settings.}, keywords = {}, pubstate = {published}, tppubtype = {article} }

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.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

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.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

This demonstrates an straight forward approach for remote robot operation independent from a specific device. Any current web browser running on a commercial off-the-shelf computer or mobile phone can be used to interact with the demo. However, it also shows the limitations of this kind of robot control. Dependent on the user\'s location and network connection, different amounts of latency come into play. Within this demo this effects the difficulty, as only fast or precise movements are possible.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }
