PhD Researcher Stefan Senk is a Ph.D. student at “Deutsche Telekom Chair of Communication Networks” at TU Dresden. He is working on the 5G Campus project whose goal is to develop 5G networks for industry partners. This allows to create new, innovative applications for human-robots-cooperation (cobots), for small startups or established companies. 5G communication technology is needed in order to fulfill the requirements, e.g. ultra low latency. Software defined networks, mobile edge computing and network slicing are some of the enabling technologies.
His main research interest is Time-sensitive Networking (TSN) and the integration of 5G as virtual TSN bridge.
He was born in Berlin, Germany and studied at the Technische Universität Dresden where he received his degree “Diplom-Ingenieur” (Dipl.-Ing.) in electrical engineering in July 2019. He has worked as a student helper for 3 years at Cloud & Heat Technologies GmbH, a startup company in Dresden working on the topic of sustainable green distributed cloud data centers.

With NFV, running network functions on general-purpose hardware is supposed to lower network latency due to reduced propagation delay. The trade-off, however, is in impaired reliability and increased processing latency, which could negatively affect Quality of Service (QoS) and Quality of Experience (QoE). We investigate the trade-off via a comprehensive measurement study exploiting a high-precision measurement method on a carrier-grade Cisco Catalyst 9500 Series switch, which provides enhanced computing capability via lightweight containerization. Baseline results on packet forwarding latency confirm that software-based forwarding is inferior to the hardware pendant. Subsequently, we deploy a more realistic application with an example for network coding and introduce a new metric, re-coding opportunities. Our study identifies a superior performance of generic hardware, but also shows advantages of in-network computing for latency-tolerable scenarios.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

However, realizing TI is a complex challenge in wireless networks like the 5G and beyond 5G mobile communication systems. 5G-TSN is an approach adopting the determinism of Time-Sensitive Networking (TSN) into 5G systems. This demo presents 5G-TSN FlexTac, a 5G and TSN combination, to achieve ultra-low latency for real-time tactile experiences. The demo showcases its effectiveness in providing immersive haptic interactions, opening avenues for virtual reality and remote surgery applications. The user can experience the Tactile Internet with haptic feedback through a cyber-physical input device. Furthermore, the user can understand the need for traffic prioritization by investigating the effects of different QoS settings in the 5G-TSN FlexTac testbed.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

Cellular-connected UAVs will benefit from ultra-reliable and low-latency communication (URLLC) in 5G and beyond networks. Their integration with Time-Sensitive Networking (TSN) via campus solutions can provide swarm robotics wireless links with deterministic behavior, flexibility, and coverage. Reliable yet cost-effective and flexible evaluation of the integration is still challenging for academia and industry. We focus on open-source testbeds due to their maturity and transparency in verifying evaluation results. Subsequently, we systematically survey and categorize testbeds in the literature that use commercial-off-the-shelf hardware. Our study outlines options for building a full-fledged testbed for integrating TSN with 5G and beyond for research and development. This study initiates one of the first steps toward facilitating future research."}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }
