Abstract
Safety-critical distributed real-time applications operating with strict temporal constraints rely on deterministic networks with low latency and jitter. Traditional fieldbus systems deliver these guarantees, but they have limited compatibility with open infrastructures and limited support for high transmission rates. Ethernet technology rises as a low-cost, high-speed, and ubiquitous alternative to fieldbus systems; however, standard Ethernet requires special arbitration mechanisms to support real-time traffic because of the standard's inherent nondeterministic behavior. This work explores the associated tradeoffs for three different solutions for real-time communication over switched Ethernet. The paper presents and discusses three architectures that modify different network components, enhancing them with additional customized modules to support time-triggered communication based on Network Code. Using the NetFPGA platform as the unified prototyping technology for all the components, we developed an open-source framework to characterize each solution using experimental data for the latency, jitter, throughput, robustness, and cost in logical resources. The results provide insights to help future developers of real-time communication technology decide which components to modify according to the requirements of their applications.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
