SLA-Aware Protection Switching in optical WDM networks
Bibliographic record
Abstract
In this paper, we present a Service Level Agreement (SLA) constrained connection provisioning scheme, namely SLA-Aware Protection Switching (SAPS) that switches between segmented protection and sub-path protection with respect to the SLA requirements of the incoming connections. SAPS is an enhancement to a previously presented connection provisioning scheme, Availability-Constrained Generalized Segment Protection (AC-GSP), that works under shared segment protection. We evaluate the performance of these proposed schemes under resource rich and resource constrained network environments by simulation, and show that, SAPS improves the performance of AC-GSP in terms of the availability per connection, blocking probability and availability satisfaction ratio. However, it utilizes more wavelengths in comparison to AC-GSP since the more segments protect the links of the working path, the higher the network availability achieved. Therefore, in a resource restricted environment, blocking ratio of SAPS approaches to that of AC-GSP while still meeting higher availability values for the provisioned connections.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
