Abstract
Finding an effective and simple unified control plane (UCP) for IP/dense wavelength division multiplexing multilayer optical networks is very important for network providers. Generalized multi-protocol label switching (GMPLS) has been in development for decades to control optical transport networks. However, it is extremely difficult to deploy in real operational products, as there is still much non-GMPLS-capable equipment. On the other hand, OpenFlow (OF), one of the most widely used software defined networking implementations, can be used as a UCP for packet and circuit switched networks [“Packet and circuit network convergence with OpenFlow,” in OFC/NFOEC, Mar. 2010]. In this paper, we propose and experimentally evaluate two solutions using OF to control both packet and optical networks (OpenFlow Messages Mapping and OpenFlow Extension). The overall feasibility of these solutions is assessed, and their performance is evaluated and compared with the GMPLS approach, using a custom-built simulator. Simulation results show that the OpenFlow Extension solution outperforms the OpenFlow Messages Mapping and GMPLS solutions.

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 it
