Abstract
While there has been many studies on the efficient design of p-cycles focusing on optimizing their spare capacity efficiency, few of them consider such a design under the wavelength continuity assumption, i.e., no wavelength converter at any node. Consequently, few authors look at the routing and wavelength assignment in the context of p-cycles, where p-cycles have to be assigned the same wavelength as the paths of which they protect at least one link. In this paper, we propose to investigate thoroughly the issue of wavelength conversion vs. wavelength continuity for p-cycles, with large scale optimization tools (decomposition techniques) in order to get an exact estimate of the consequences of the wavelength continuity assumption on the spare capacity requirements and on the provisioning cost. The recourse to decomposition techniques allows the design of exact efficient scalable models contrarily to heuristics which ensure scalability but no accuracy guarantee. In particular, it allows an on-line generation of improving p-cycles, one after the other with respect to the objective, instead of a costly computing time off-line generation of p-cycles as in previous studies, a key issue for a scalable solution. Numerical results show that the difference between the capacity requirement under wavelength conversion vs. under wavelength continuity is meaningless. Consequently, in view of the reduced provisioning cost (saving at least on the converters), we advocate the design of p-cycles under a wavelength continuity assumption.

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.
