IETF RPL DIS Modifications and Applications (draft-ietf-roll-dis-modifications-02)

This document augments [RFC6550] by defining new DODAG Information Solicitation (DIS) flags and options that enable a RPL node to exert finer control over how neighboring RPL routers respond to its DIO solicitations. In addition, this document describes several use cases that motivate these DIS extensions and illustrate scenarios in which enhanced control of DIO responses improves network efficiency, responsiveness, and robustness.
