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.
