Abstract

fetched live from OpenAlex

Specifying and monitoring service level agreements (SLA) has been the subject of intensive research. However, methods of enforcing SLA have not addressed the specific issues of composite services (CS). Our work focuses on the problem of keeping prearranged SLAs for service workflows including workflows supporting long lived transactions (e.g. WS-BA). As a solution we offer scheduling of component service requests. The latter is based on regaining control over legacy services by means of transparent proxies and later scheduling of their invocations. Various heuristics based policies are evaluated under two different types of service level agreements. The policies vary from the simpler, operating only on the base of business value, to the more complex which also consider Quality of Service requirements, topologies of workflows, utilization of components services, etc. The experiments conducted over the model, which precisely captures the behavior of web services, reveal the benefits of providing schedulers with various types of context.

Full frame distilled prediction

Teacher imitation

Not 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.
