HPQS: A Fast, High-Capacity, Hybrid Priority Queuing System for High-Speed Networking Devices
Bibliographic record
Abstract
In this paper, we present a fast hybrid priority queue architecture intended for scheduling and prioritizing packets in a network data plane. Due to increasing traffic and tight requirements of high-speed networking devices, a high capacity priority queue, with constant latency and guaranteed performance is needed. We aim at reducing latency to best support the upcoming 5G wireless standards. The proposed hybrid priority queuing system (HPQS) enables pipelined queue operations with almost constant time complexity in practice. The proposed architecture is implemented in C++, and is synthesized with the Vivado High-Level Synthesis (HLS) tool. Two configurations are proposed. The first one is intended for scheduling with a multi-queuing system for which implementation results of 64 up to 512 independent queues are reported. The second configuration is intended for large capacity priority queues, that are placed and routed on a ZC706 board and a XCVU440-FLGB2377-3-E Xilinx FPGA supporting a total capacity of 1/2 million packet tags. The reported results are compared across a range of priority queue depths and performance metrics with existing approaches. The proposed HPQS supports links operating at 40 Gb/s.

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.
