Contreras and MEHMET DURMUS and Reshad Rahman}, title = {{Fast Network Notifications Problem Statement}}, pagetotal = 19, year = 2026, month = jul, day = 18, abstract = {Many network applications, ranging from Artificial Intelligence (AI) /Machine Learning (ML) training/inference to cloud services, require networks with various combination of high bandwidth, low delay and low jitter and minimal packet loss in data transfer. This requires that the networks must rapidly adapt to the presence of faults, degradation and congestion. However, existing routing and traffic management mechanisms often face limitations in responsiveness, coverage, and operational complexity, particularly in large-scale and high-bandwidth network environments (e.g. data center (DC) and data center interconnect (DCI)). A good and timely understanding of network conditions can help to enable faster response to critical events, so as to enable the selection of paths with reduced latency and improve network utilization. This document describes the gap analysis and the need for fast network notification, and identifies the set of problems which a fast network notification solution needs to address.}, }
