Abstract
The thesis proposes a delay asymmetry correction (DAC) model to enhance the IEEE 1588 synchronization protocol. The purpose of this work is to mitigate the effects of unpredictable packet delay variations (PDV), which cause asymmetric link delays on timing packets, in order to improve the synchronization accuracy of the slave clock with respect to the master clock. This is done by computing the time difference between the master and the slave clock in the presence of traffic in a network. The NS-2 results indicate that the proposed solution improves the slave accuracy by measuring the correct offset value in a slave clock for asymmetric communication link delays. The solution results show that the slave clock is able to achieve high synchronization accuracy in the presence of various bi-directional traffic loads, network congestions, and temporary network outage. Furthermore, when there is a routing path change due to the failure in the network, the solution also improves the accuracy of the slave clock with respect to the master clock. However, the proposed solution does not perform well when it is incorporated with the AOCM model.

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
