Time-Sensitive Networking (TSN) is intended to enable deterministic communication over inexpensive Ethernet networks. Standardized by the IEEE TSN working group, TSN enables precise control of time synchronization, traffic shaping, reliability enhancements, and network administration to answer the demands of industrial control applications. Subsequently, there is a significant need to enable turnkey research and implementation efforts. However, a current lack of open-sourced testbed implementations to investigate and study the behavior of TSN network devices limits verification to simulation and theoretical models. We introduce a publicly available, flexible, and open-sourced measurement testbed for evaluating TSN in the context of industrial automation applications to address the need to perform real-world measurements. In this contribution, we describe our testbed combining Commercial-Off-The-Shelf (COTS) hardware and existing open-source tools as a platform for in-depth evaluation of TSN devices. Providing detailed TSN backgrounds, we describe an in-depth performance analysis for our implementation. For a common Tactile Internet scenario, we observe an accuracy of close to 5 ns achievable with our publicly available COTS setup.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

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} }

In order to fulfill those requirements in real applications, it is necessary to implement traffic encryption on the physical layer rather than the application layer. Nevertheless, the aforementioned integration is a computing intensive task, in which many arithmetic operations are involved. Therefore, hardware acceleration may be a solution to provide enough throughput, while maintaining low power consumption. In this paper we present the implementation of hardware acceleratorsfor cryptographic algorithms on heterogeneous multi-core dedicated hardware, using the state-of-the-art WolfSSL software embedded library. By comparing our implementation to software-only solutions in terms of throughput and delay using variabledata sets, we find performance improvements up to three orders of magnitude as well as around 80% latency reductions in the computing time.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }
