Abstract

   As emerging technology, Augmented Reality (AR) and Virtual Reality
   (VR) bring up a lot of challenges to technologies such as information
   display, image processing, fast computing and networking.  This
   document will analyze the requirements of AR and VR to networking,
   especially to transport protocol.

1.  Introduction

   Virtual Reality (VR) and Augmented Reality (AR) technologies have
   enormous potential in many different fields, such as entertainment,
   remote diagnosis, or remote maintenance.  AR and VR applications aim
   to cause users to perceive that they are physically present in a non-
   physical or partly non-physical world.  However, slightly unrealistic
   artefacts not only distract from the sense of immersion, but they can
   also cause `VR sickness' [VR-Sickness] by confusing the brain
   whenever information about the virtual environment is good enough to
   be believable but not wholly consistent.

   This document is based on the assumption and prediction that the
   current localized AR/VR will inevitably evolve to cloud based AR/VR.
   Since cloud processing and state will be able to supplement local AR/
   VR devices, helping to reduce their size and power consumption, and
   to provide much more content resource and flexibility to the AR/VR
