Abstract
Delay jitter of data packets is known to be a crucial quality of service measure especially for real-time applications (e.g., VoIP). It takes place as a result of the queuing, scheduling, and routing latencies within the network. However, control schemes that directly tackle the jitter problem in today's advanced wireless systems are rare. To enable such schemes, proper modeling of the packet delay jitter is an essential preliminary step. This letter presents a comprehensive mathematical modeling for the packet delay jitter in a simple queuing system with one traffic buffer of infinite length, one server, and single hop. In contrast to independent and identically distributed models, our analysis focuses on the correlated nature of service intervals. The presented models study different scenarios and parameters for the queue in terms of the system's utilization and the probability distribution of data packets' service and interarrival times, respectively. Numerical simulations demonstrate the high accuracy achieved by the presented models.

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
