abstract = {The industry is striving to deploy private cellular networks in their 

factories. 

The envisioned use cases, such as industrial automation, require 

Ultra-Reliable and Low-Latency Communications (URLLC). 

In 5G, the User Plane Function (UPF) handles user traffic and hence 

significantly influences the performance in terms of latency and 

throughput. 

However, present UPFs are often user-space applications running on 

commercial off-the-shelf (COTS) servers introducing computational delays 

that follow long-tailed distributions. 

In this work, we compare modern packet processing acceleration technologies 

such as XDP, DPDK, and P4 and their respective tail-latency performance. 

Our results demonstrate the clear advantage of hardware-based P4 

implementations in terms of reduced tail-latency of about 6 μs at a 

percentile of 99.999% for small packets. 

Furthermore, we also demonstrate that software-based frameworks can compete 

with hardware-based approaches. 

For example, DPDK achieves tail-latencies of approximately 23 μs at a 

percentile of 99.999%. 

Based on our findings, we illustrate the trade-offs between low-cost 

software- and high-performant hardware-based packet processing systems.},

abstract = {5G campus networks, whose advantages include 

flexible deployment, can be a promising candidate for production 

plants to complement existing Wifi-based networks. Toward 

that goal, 5G has to satisfy strict requirements about real-time 

communication to facility novel use cases. However, the realtime- 

capability of 5G is not well understood yet. In this work, we 

deliver insights into the functioning of 5G NR RAN Release 

15, which includes actual one-way delay and Round-Trip Time 

(RTT) measurements for Downlink and Uplink in a private 5G 

Standalone campus network. The extensive measurement results 

reveal that these delays are correlated, and the corresponding 

RTT, i.e. the sum of Downlink and Uplink delays, is discreetly 

clustered, ranging between 12ms and 40ms. The measurements 

also show that the distribution of RTTs is mainly dependent on 

the packet rates and their inter-arrival times. Our study helps 

expand the current understanding of 5G used for latency-critical 

applications. We make the code and the measurement data traces 

publicly available as the IEEE DataPort 5G Campus Networks: 

Measurement Traces dataset (DOI 10.21227/xe3c-e968).},
