Abstract

   The wireless medium presents significant specific challenges to
   achieve properties similar to those of wired deterministic networks.
   At the same time, a number of use cases cannot be solved with wires
   and justify the extra effort of going wireless.  This document
   presents some of these use-cases.

1.  Introduction

   Reliable and Available Wireless (RAW) is an effort that extends
   DetNet to approach end-to-end deterministic performances over a
   network that includes scheduled wireless segments.  The wireless and
   wired media are fundamentally different at the physical level.
   Enabling thus reliable and available wireless communications is even
   more challenging than it is in wired IP networks, due to the numerous
   causes of loss in transmission that add up to the congestion losses
   and the delays caused by overbooked shared resources.  To provide
   quality of service along a multihop path that is composed of wired
   and wireless hops, additional methods needs to be considered to
   leverage the potential lossy wireless communication.

   Traceability belongs to Operations, Administration, and Maintenance
   (OAM) which is the toolset for fault detection and isolation, and for
   performance measurement.  More can be found on OAM Tools in
   [RFC7276].

   The main purpose of this document is to detail the requirements of
   the OAM features recommended to construct a predictable communication
   infrastructure on top of a collection of wireless segments.  This
   document describes the benefits, problems, and trade-offs for using
   OAM in wireless networks to provide availability and predictability.
