Abstract:

   The Routing Protocol for Low-Power and Lossy Networks (RPL), defined
   in RFC 6550, enforces a single Mode of Operation (MOP) across all
   nodes within a DODAG.  This rigidity prevents heterogeneous devices
   from independently selecting their forwarding behavior and creates
   permanent isolation between DODAGs operating with different MOPs.

   This document defines HyMRPL, a Hybrid Mode of Operation (MOP=6) that
   enables per-node functional profiles within a single DODAG.  Nodes
   independently adopt Class-S (storing-like) or Class-N (non-storing-
   like) behavior without modifying RPL control message formats.
   Additionally, this document specifies an Inter-DODAG Bridge mechanism
   that uses MOP Extension (MOPex) signaling to interconnect DODAGs with
   different MOPs through cross-DODAG route injection.

   The mechanisms introduce zero additional control messages, maintain
   full backward compatibility via the J-flag in extended options, and
   have been validated with a functional implementation demonstrating
   100% packet delivery ratio across MOP boundaries.
