Towards AI/ML-Driven Network Traffic Engineering
This paper introduces AI/ML as a transformative approach to Traffic Engineering (TE) in complex, planet-scale networks. Current TE methods, often based on distributed protocols or centralized optimization, struggle with the dynamism and scale of modern cloud networks. AI/ML offers a promising path to near-optimal, real-time TE by analyzing diverse data modalities (graphs, time-series, logs) and employing control algorithms like Reinforcement Learning. The study surveys existing TE solutions, categorizes them, and identifies key challenges and opportunities for AI/ML to enhance network stability, efficiency, and user experience.

Target for Real-time Network Control
The ambition for AI/ML in network control is to achieve near-optimal network adjustments in milliseconds, far surpassing current human-driven or static optimization capabilities. This real-time responsiveness is critical for dynamic, planet-scale networks with unpredictable traffic demands and topology changes.
Case Study: FlowGNN for Traffic Splitting
The GDDR paper proposes a GNN-based routing strategy, leveraging Reinforcement Learning (RL) to optimize traffic flows. It first precomputes up to four possible paths for each flow and then creates a bipartite graph (FlowGNN) with path nodes and original network edge nodes. RL then learns how to optimally split traffic across these precomputed paths. This approach effectively addresses the complexity of traffic splitting in large networks by combining graph neural networks with learning-based decision-making. The challenge remains in extending such methods to real-time, online operational networks.
