Performance evaluation of MPEG2 video using guaranteed service over IP-ATM networks
Bibliographic record
Abstract
The paper studies the delay-jitter performance of MPEG2 video transmitted over a connection oriented internetwork consisting of various possible mixes of IP and ATM switches. It is shown that all-IP switching outperforms all-ATM switching when the network load is high, and vice versa at low network load. Mixed IP and ATM switching is shown to perform between these two cases. Several methods of mapping IP traffic descriptors to the ATM counterparts are assessed. When used by every ATM connection, the worst case mapping (A. Birman et al.) performs worse than other mapping methods-such as the Uniform mapping (M.W. Garrett and M. Borden). The Native ATM (i.e., null IP layer) is shown to perform very closely to IP-over-ATM insofar as packet delay-jitter is concerned. However, the buffer size requirement of the Native ATM is considerably less.

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.
