Liu Huawei Technologies February 2, 2021 AODV based RPL Extensions for Supporting Asymmetric P2P Links in Low-Power and Lossy Networks draft-ietf-roll-aodv-rpl-09 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 (AODV-RPL). Paired Instances are used to construct directional paths, in case some of the links between source and target node are asymmetric.
