Abstract

fetched live from OpenAlex

Next-generation networks are endowed with enhanced capabilities thanks to software-defined networking and network function virtualization (NFV). There is a radical shift from device-centric to experience-driven environments of which data is the primary driver behind its running engines. In this paper, we consider joint topology design, traffic routing and NF placement for unicast NFV-enabled services. We develop an end-to-end model-free deep reinforcement learning (RL) framework to dynamically allocate processing and transmission resources, while considering time-varying network traffic patterns. First, we provide a flexible pre-processing technique that represents and reduces the state space and action space of the considered joint problem for the deep RL algorithm. Second, we present a deep deterministic policy gradient (DDPG) algorithm that is enhanced with a model-assisted exploration procedure. Due to the multiple resource types with strongly adverse effects, the existing vanilla DDPG algorithm cannot achieve consistent performance. The model-assisted exploration procedure, which utilizes a perturbed step-wise sub-optimal integer linear program, bootstraps and stabilizes the vanilla DDPG algorithm and finds optimal solutions efficiently.

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.
