Abstract
Global broadband networking is an emerging technology aiming at providing broadband services all over the world using a constellation of satellites with on-board ATM switching capabilities. The authors propose an architecture for the ATM switches to be used on board satellites and identify both performance and physical requirements that make them distinct from terrestrial switches. Based on these requirements, a shared memory architecture is proposed. A major aspect of the switch design is the buffer management controller and the way it provides QoS to several classes of loss and delay priority traffic. A circular sorting queue is proposed as an efficient solution in terms of performance and implementation. It is also analysed using an M/G/1/K model and a supplementary variable method. This analysis is used to estimate the buffer size required and to evaluate the performance of the architecture. Some implementation guidelines for satellite switches are also discussed along with a low-power VLSI implementation of the circular queue.

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
