           In Network Computing Enablers for Extended Reality
                       draft-montpetit-coin-xr-03

Abstract

   Augmented Reality (AR) and Virtual Reality (VR), combined as Extended
   Reality or XR, challenge networking technologies and protocols
   because they combine the features of fast information display, image
   processing, computing and forwarding.  This document presents some of
   these challenges and how adding computing in the network could
   respond to them.

1.  Introduction

   Virtual Reality (VR) and Augmented Reality (AR) taken together as
   Extended Reality or XR are at the center of a number of technological
   advances in many different fields, including not only gaming and
   entertainment but immersive journalism, remote diagnosis and
   maintenance, telemedicine, manufacturing and assembly and smart
   cities.

   But with the emergence of the edge and the programmability of network
   elements all the way from the data center to the users the
   possibility of creating networked, multiparty/multisource and
   interacting XR comes closer to reality.  This document wants to
   review what is necessary for the current localized and cloud enhanced
   XR to evolve to a more distributed and edge centric architecture to
   support advanced immersive application and services.  It assumes that
   network programmability will enable to tailor the network to the XR
   requirements.  This document is about requirements not solutions per
   se but will mention work that has already been done towards a more
   networked XR including Information Centric architectures, Artificial
   Intelligence and in network coding.  The networked functionality
   should enable to supplement local XR services and devices while
   keeping the very low latency and the very high data rates that are
   required by XR.
