For programmable data planes, however, it is more challenging to benefit from these advantages, given the complexity of ML models and their limited resource capabilities. In this paper, we propose ART, an attempt to simplify ML-based solutions for routing, so that they can ``fit{"}, i.e., be executed, on P4 switches. To provide such model simplification, ART relies on efficient knowledge distillation techniques, converting, in particular, Deep Reinforcement Learning (DRL) models into simpler a Decision Tree (DT). Our evaluation results validate the accuracy of the extracted model and the application of the model logic directly into switches with little impact, paving the way for a more reactive data plane programmability via machine learning integration.} }
