Abstract

   Packet Replication and Elimination is a method in which several
   copies of a data packet are sent in the network in order to achieve
   high reliability and low jitter.  This document details how to apply
   Packet Replication and Elimination in RPL, especially how to exchange
   information within RPL control packets to let a node better select
   the different parents that will be used to forward the multiple
   copies of a packet.  This document also describes the Objective
   Function which takes advantage of this information to implement
   multi-path routing.

1.  Introduction

   Networks in the industrial context must provide stringent guarantees
   in terms of reliability and predictability, with this domain being
   one of main ones addressed by Deterministic Networking [RFC8557].
   Packet Replication and Elimination (PRE)
   [I-D.papadopoulos-raw-pareo-reqs] is a technique which allows
   redundant paths in the network to be utilized for traffic requiring
   higher reliability.  Allowing industrial applications to function
   over wireless networks requires the application of the principles and
   architecture of Deterministic Networking [RFC8655].  This results in
   designs which aim at optimizing packet delivery rate and bounding
   latency.  Additionally, nodes operating on battery need to minimize
