The findings indicate that Raspberry Pi-based NTP servers provide a practical and economical platform for the performance monitoring of industrial NTP servers, supporting the long-term evaluation of time dissemination services.
Abstract
Accurate time dissemination is essential for telecommunications, scientific instrumentation, industrial control, and distributed computer systems, motivating the development of cost-effective timing solutions. This work presents the design, implementation, and evaluation of low-cost Network Time Protocol (NTP) Stratum-1 servers based on Raspberry Pi platforms disciplined by a pulse-per-second (PPS) signal derived from a UTC(k) reference. The proposed systems were configured and optimized to provide traceable time synchronization services and were assessed through long-term comparisons against institutional Stratum-1 reference servers. Time offset and network delay were continuously monitored over extended observation periods, while synchronization stability was characterized using Time Deviation (TDEV) analysis. The findings indicate that Raspberry Pi-based NTP servers provide a practical and economical platform for the performance monitoring of industrial NTP servers, supporting the long-term evaluation of time dissemination services.
The Precision Time Protocol has gained significant importance for time synchronisation in high-demand services such as 5G and 6G telecommunications, real-time and low-latency applications, and industrial control. We present a distributed monitoring scheme based on control plane telemetry explorers that extract insightf...

PURPOSE
Interoperable, vendor-independent communication between medical devices in operating rooms has been enabled by the ISO IEEE 11073 Service-oriented Device Connectivity (SDC) standard since 2019. However, mechanisms for predictable and deterministic transmission behavior have not yet been standardized. One approa...

Industrial facilities increasingly rely on continuous telemetry acquisition to support condition monitoring, operational awareness, and predictive maintenance. However, many existing edge-to-cloud monitoring systems employ complex communication architectures involving message brokers and middleware, which can increase...

An open-source E3Controller for OCUDU is designed as a sidecar daemon so the E3 protocol stack, service-model logic, and dApp interactions live entirely outside RAN core processing, which is touched only through well-defined instrumentation hooks.

This paper presents a software-defined Time-Sensitive Networking (TSN) architecture that implements the IEEE 802.1Qcr Asynchronous Traffic Shaper (ATS) using Extended Berkeley Packet Filter (eBPF) technology within Linux-based TSN bridges. By moving traffic shaping logic to the kernel level, our solution eliminates the...
