  Problem Statement and Use Cases of Application-aware IPv6 Networking

Abstract

   Network operators are facing the challenge of providing better
   network services for users.  As the ever developing 5G and industrial
   verticals evolve, more and more services that have diverse network
   requirements such as ultra-low latency and high reliability are
   emerging, and therefore differentiated service treatment is desired
   by users.  However, network operators are typically unaware of which
   applications are traversing their network infrastructure, which means
   that only coarse-grained services can be provided to users.  As a
   result, network operators are only evolving their infrastructure to
   be large but dumb pipes without corresponding revenue increases that
   might be enabled by differentiated service treatment.  As network
   technologies evolve including deployments of IPv6 and SRv6, the
   programmability provided by IPv6 and SRv6 encapsulations can be
   augmented by conveying application related information into the
   network.  Adding application knowledge to the network layer allows
   applications to specify finer granularity requirements to the network
   operator.

   This document analyzes the existing problems caused by lack of
   application awareness, and outlines various use cases that could
   benefit from an Application-aware IPv6 Networking (APN6)
   architecture.
