Point-to-point (P2P) communication between arbitrary routers in a Low-power and Lossy Network (LLN) is a key requirement for many home and commercial building automation applications [RFC5826] [RFC5867]. The IPv6 Routing Protocol for LLNs (RPL) [RFC6550] constrains the LLN topology to a Directed Acyclic Graph (DAG) built to optimize the routing costs to reach the DAG's root. The P2P routing functionality, available under RPL, has the following key limitations:

A Mechanism to Measure the Routing Metrics along a Point-to-Point Route in a Low-Power and Lossy Network
This document specifies a mechanism that enables a Routing Protocol for Low-power and Lossy Networks (RPL) router to measure the aggregated values of given routing metrics along an existing route towards another RPL router, thereby allowing the router to decide if it wants to initiate the discovery of a better route.
