   Operations, Administration and Maintenance (OAM) features for RAW

Abstract

   Some critical applications may use a wireless infrastructure.
   However, wireless networks exhibit a bandiwidth of several orders of
   magnitude lower than wired networks.  Besides, wireless transmissions
   are lossy by nature; the probability that a packet cannot be decoded
   correctly by the receiver may be quite high.  In these conditions,
   guaranteeing the network infrastructure works properly is
   particularly challenging, since we need to address some issues
   specific to wireless networks.  This document lists the requirements
   of the Operation, Administration, and Maintenance (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 achieve Service Level Objectives (SLO).
