Fast backward congestion notification mechanism for TCP congestion control
Bibliographic record
Abstract
The novel mechanism proposed uses a simple implementation to inform the traffic source at a very early stage that the network is becoming overloaded or congested and ask the source to slow down its transmission rate. Since TCP uses acknowledgments (ACKs) to adjust the number of packets sent over the network, the basic idea of our scheme is to control (or delay) TCP ACKs in the access node where its forward connection through the network is congested. To shorten the control loop, the congested network node generates ICMP (Internet control message protocol) source quench to initiate ACK control at the access node at the onset of congestion. By theoretical analysis and simulations, the mechanism is proven to be very effective in improving TCP throughput and fairness performance and reducing buffer occupancy. In particular, formulae for buffer occupancy and average throughput are derived relative to the distance between the congested node and the source terminal. It is important to note that TCP behavior does not have to be amended in any way.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
