abstract = {Network Function Virtualization (NFV) is envisioned to provide the 

foundation for a dynamic, high-performance multi-layer network 

architecture. 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.},

abstract = {The Tactile Internet (TI) is a revolutionary communication platform that 

enables perceived real-time interaction between humans and machines, such 

as in remote surgery. 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.},

abstract = {\"{U}nmanned Aerial Vehicles (UAVs) have developed substantially in various 

practical use cases and require reliable wireless connections. 

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."},
