This document looks at different data flows through Low-Power and
Lossy Networks (LLN) where RPL (IPv6 Routing Protocol for Low-Power
and Lossy Networks) is used to establish routing. The document
enumerates the cases where RPL Packet Information (RPI) Option Type
(RFC 6553), RPL Source Route Header (RFC 6554), and IPv6-in-IPv6
encapsulation are required in the data plane. This analysis provides
the basis upon which to design efficient compression of these
headers. This document updates RFC 6553 by adding a change to the RPI
Option Type. Additionally, this document updates RFC 6550 by defining
a flag in the DODAG Information Object (DIO) Configuration option to
indicate this change and updates RFC 8138 as well to consider the new
Option Type when the RPL Option is decompressed.
This document is a product of the Routing Over Low power and Lossy networks
Working Group of the IETF.
This is now a Proposed Standard.
