Abstract
This paper proposes a novel framework for managing the resource provisioning of reliable virtual networks (VN) in the cloud. This includes handling the placement of VN requests while providing availability guarantees, as well as reconfiguring/adapting their placement as their request changes over time. This is particularly interesting for services with periodic resource demands. Given the heterogeneous failure rates of physical network components, the placement and reconfiguration must ensure that the selected hosts for each VN meets its availability requirements. The existing work on availability-aware VN placement has overlooked the case of “availability over-provisioning,” as well as the fact that VN requests are subject to change over time. To this extent, we propose a novel framework that consists of two main modules; JENA: a tabu-based availability-aware resource allocation (embedding) module for VNs that achieves “just-enough” availability guarantees, and ARES: a reliable reconfiguration module to adapt the embedding of hosted services as they scale. Further, we introduce the concept of “protection-domains” and “protection-policies” to equip our proposed modules with the ability to augment services with redundant/backup nodes to enhance their reliability. Our numerical results show that our framework enhances network's admissibility (with 33% lower blocking compared to existing work), and in return increases the cloud provider's long term revenue, compared to peer and benchmark algorithms.

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
