Abstract:

   The Routing Protocol for Low-Power and Lossy Networks (RPL, RFC 6550)
   enables data packet routing along a Destination-Oriented Directed
   Acyclic Graph . However, the default route establishment mechanism
   relies on hop-by-hop forwarding along the DODAG, which may not always
   provide optimal routing efficiency.  This document introduces the
   concept of DAO Projection, a mechanism that allows a RPL root or an
   external controller to install optimized routes within the RPL
   domain.  DAO Projections enable the creation of optimized unicast or
   multicast routes that do not strictly follow the DODAG structure,
   thereby improving routing efficiency, reliability, availability, and
   resource utilization in the RPL domain.  The document specifies two
   types of projected routes—storing mode and non-storing mode
   projections—and outlines the signaling procedures necessary to
   establish, maintain, and remove these routes.  This document extends
   RFC 6550, RFC 6553, and RFC 8138.
