     Asymmetric AODV-P2P-RPL in Low-Power and Lossy Networks (LLNs)
                      draft-ietf-roll-aodv-rpl-07

Abstract

   Route discovery for symmetric and asymmetric Point-to-Point (P2P)
   traffic flows is a desirable feature in Low power and Lossy Networks
   (LLNs).  For that purpose, this document specifies a reactive P2P
   route discovery mechanism for both hop-by-hop routing and source
   routing: Ad Hoc On-demand Distance Vector Routing (AODV) based RPL
   protocol.  Paired Instances are used to construct directional paths,
   in case some of the links between source and target node are
   asymmetric.
