Noction IRP is an edge-deployed BGP optimization platform that analyzes traffic in real-time to detect congestion, link failures, and performance degradation. The system continuously probes network routes across all available providers, measuring latency, packet loss, and historical reliability to identify the best paths for both inbound and outbound traffic. IRP manages ingress and egress bandwidth intelligently, distributing traffic flows across providers to minimize costs while maintaining quality of service. The platform automatically reroutes traffic when the thresholds are reached, ensuring optimal delivery for all traffic types. Built-in Automatic Anomaly Detection (AAD) provides DDoS protection by analyzing traffic behavior and identifying deviations from established baselines. AAD detects volumetric floods, amplification attacks, TCP SYN floods, and application-layer threats, then executes mitigation automatically using BGP FlowSpec and RTBH mechanisms.
