              Reliable and Available Wireless Technologies
                   draft-thubert-raw-technologies-03

Abstract

   This document presents a series of recent technologies that are
   capable of time synchronization and scheduling of transmission,
   making them suitable to carry time-sensitive flows with requirements
   of both reliable delivery in bounded time, and availability at all
   times, regardless of packet transmission or individual equipement
   failures.
