Hi WG, I support the adoption of this document. From the operator's perspective, existing feedback mechanisms in WAN are too slow and coarse-grained for dynamic workloads like AI, leading to inefficient utilization, cascading congestion, and costly application stalls. Fast notification focuses on sub-millisecond, targeted notifications for traffic engineering, ensuring the WAN has higher reliability, optimized capacity, and the ability to meet stringent SLAs, while reducing resource waste.

A good and timely understanding of network operational status, such as congestion and failures, can help to improve network utilization, enable the selection of paths with reduced latency, and enable faster response to critical events. This document describes the existing problems and why a new set of fast network notification solutions are needed.
