Towards AI/ML-Driven Network Traffic Engineering
This paper presents a comprehensive analysis of AI/ML's role in Network Traffic Engineering (TE). It reviews existing approaches, from traditional system heuristics to advanced optimization and control theory, highlighting the challenges of dynamism and scale in large networks. The analysis identifies key opportunities for AI/ML in learning network states (graph, time-series, logs) and real-time control (Reinforcement Learning), proposing a shift towards near-optimal, adaptive TE solutions for planet-scale cloud networks.

RL-driven Adaptive Routing
Studies like GDDR (GNN-based Data-driven Routing) and TEAL (Learning-accelerated Optimization) propose using Reinforcement Learning (RL) with Graph Neural Networks (GNNs) to learn network states and make routing decisions. RL agents are trained to find optimal paths by receiving rewards based on collective network state, enabling adaptive traffic placement and reaction to network degradation.
Key Outcome: RL enables autonomous, near-optimal routing in dynamic, large-scale networks.

Your AI/ML-Driven TE Transformation Roadmap
A phased approach ensures smooth integration and measurable outcomes for your enterprise network.
Phase 1: Data Collection & Baseline Establishment
Implement comprehensive data pipelines for network metrics (utilization, latency, loss), topology changes, and log data. Establish baseline performance metrics and identify current TE bottlenecks.
Phase 2: AI/ML Model Development & Simulation
Develop and train initial AI/ML models (e.g., GNNs for state prediction, RL agents for routing) using historical and simulated data. Validate model performance against baseline scenarios in a controlled environment.
Phase 3: Phased Rollout & A/B Testing
Gradually deploy AI/ML-driven TE solutions in non-critical segments of the network using A/B testing methodologies. Monitor performance, stability, and reactiveness to real-time changes, iterating on model refinements.
Phase 4: Full-Scale Integration & Continuous Optimization
Integrate AI/ML TE across the entire network, ensuring seamless operation. Implement continuous learning and retraining mechanisms for models to adapt to evolving traffic patterns and network conditions, achieving sustained near-optimal performance.
