Abstract
SDN has the potential to simplify network configuration and reduce management complexity. In today¿s networks control and forwarding functions are tightly coupled and embedded within each switch/router. SDN, in contrast, accumulates the control functionality in one or more dedicated network entities called controllers, which provide a unified interface to configure and control the network. Packet forwarding, on the other hand, remains the responsibility of the switches/routers. Many datacenter networks have benefited from the abstraction provided by SDN. However, in a Wide Area Network (WAN) a single controller becomes a performance bottleneck. Multiple controller solutions are proposed as a natural consequence. In this article we present the requirements, design alternatives, and a possible management architecture for a single administrative domain WA-SDN. We also discuss the functional components that should be present in a multi-controller architecture for managing WA-SDN deployments.

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
