On SLA constraints in dynamic bandwidth allocation for long-reach passive optical networks
Bibliographic record
Abstract
Long-Reach Passive Optical Network (LRPON) technology seems to be a strong candidate for next generation optical access networks. LRPON aims to combine the advantages of optical metro and access networks before the backbone by offering long feeder distance and high split ratio. On the other hand, long feeder distance causes long propagation delay while together with high split ratio they lead to longer packet delay. In order to decrease packet delay, we have recently proposed a QoS-aware bandwidth allocation scheme which is called as Periodic Gate Optimization with QoS-awareness (PGO-QoS). This scheme is based on multi-threaded MPCP that has been previously proposed in the literature. In this paper, we briefly present PGO-QoS and discuss the impacts of buffer size on its performance under a feeder distance of 100 km. We show that PGO-QoS leads to shorter average delay than multi-threaded MPCP while slightly decreasing the packet loss ratio. As expected, larger buffer size increases the packet delay, especially under heavy loads. However, changing the buffer size does not affect the relative performance of PGO-QoS to the multi-threaded MPCP. Furthermore, we evaluate the effects of pre-specified delay bounds on the performance of PGO-QoS where each ONU runs an estimation to determine whether an incoming packet can reach the OLT within its delay bound.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
