Throughput and delay performance of transport user in congestion controlled hybrid ATM/TDMA networks
Bibliographic record
Abstract
The end-to-end throughput and delay performance characteristics are analyzed for a virtual circuit (VC) transport user in a hybrid asynchronous transfer mode/time division multiple access (ATM/TDMA) network. An automatic repeat request (ARQ) transport user is assumed with an underlying ATM cell-level global congestion control in an ATM multiplexer node. The analysis is based on the interaction of packet level control with the queue management at the ATM cell level. The transport user is assumed over M-node VC to analyze the throughput and delay using Norton equivalent queueing model. The transport layer service characteristic of the model is obtained from the end-to-end protocol efficiency of Go-Back-N (GBN) and selective repeat (SR) ARQ schemes. The ATM layer is assumed with a leaky bucket (LB), virtual leaky bucket (VLB), modified LB (mLB), or modified VLB (mVLB) congestion control scheme. A global congestion control scheme prioritizes transit traffic over local traffic, and ensures quality of service (QOS) to several classes of service. Based on the global congestion status, the transport users modulate their end-to-end flow control parameters, i.e., packet size in case of video and voice users, and window size in case of data users. The probability of cell-loss at the ATM layer is reflected at the transport layer to derive the effective throughput and delay characteristics. The mVLB scheme consistently provided better end-to-end throughput and delay performance for both GBN and SR transport users.

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.
