Abstract

   This document looks at different data flows through LLN (Low-Power
   and Lossy Networks) where RPL (IPv6 Routing Protocol for Low-Power
   and Lossy Networks) is used to establish routing.  The document
   enumerates the cases where RFC 6553, RFC 6554 and IPv6-in-IPv6
   encapsulation is required.  This analysis provides the basis on which
   to design efficient compression of these headers.
