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

   RAW (Reliable and Available Wireless) is an effort to provide
   deterministic behavior over a network that includes a wireless
   physical layer.  Enabling the wireless communication reliable and
   available is even more challenging than it is with wires, 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 .

   The main purpose of this document is to details the requirements of
   the OAM features recommended to construct a predictable communication
   infrastructure on top of a collection of wireless networks.  In
   particular, we expect to provide packet loss evaluation, self-testing
   and automated adaptation to enable trade-offs between resilience and
   energy consumption.

   This document describes the benefits, problems, and trade-offs for
   using OAM in wireless networks to provide availability and
   predictability.

   In this document, the term OAM will be used according to its
   definition specified in [RFC6291].  We expect to implement an OAM
   framework in RAW networks to maintain a real-time view of the network
   infrastructure, and its ability to respect the Service Level
   Agreements (delay, reliability) assigned to each data flow.
