Abstract
This letter presents an analytical model that jointly exploits the buffer dynamics of both the sending and receiving nodes to find the optimum number of byte‐level and packet‐level forward error correction (FEC) units for real‐time multimedia transmission over wireless networks. The proposed analytical model first provides an optimum number of FEC units required at the byte‐level, and then chooses the number of FEC units at the packet‐level based on current channel and network conditions. The accuracy of the proposed model is dependent on two parameters: the variable deadline‐time at the byte‐level and fixed round‐trip time (RTT) delay at the packet‐level. Numerical results demonstrate the effectiveness of the model in reducing the unrecoverable error probability, which is achieved when the byte‐level FEC scheme is supplemented by the packet‐level FEC scheme.

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
