   Implementing Packet Replication and Elimination from/to the RPL root
   requires the ability to forward copies of packets over different
   paths via different RPL parents.  Selecting the appropriate parents
   to achieve ultra-low latency and jitter requires information about a
   node's parents.  This document details what information needs to be
   transmitted and how it is encoded within RPL control packets to
   enable this functionality.  This document also describes Objective
   Function which take advantage of this information to implement multi-
   path routing.
