Abstract

   The Routing Protocol for Low-Power and Lossy Networks (RPL)    specification defines a generic Distance Vector protocol that is    adapted to a variety of network types by the application of specific    Objective Functions (OFs).  An OF states the outcome of the process    used by a RPL node to select and optimize routes within a RPL    Instance based on the Information Objects available; an OF is not an    algorithm.

   This document specifies a basic Objective Function that relies only    on the objects that are defined in the RPL and does not use any    protocol extensions.
