              6LoWPAN Routing Header And Paging Dispatches
                   draft-ietf-6lo-routing-dispatch-03

Abstract

   This specification introduces a new 6LoWPAN dispatch type for use in
   6LoWPAN Route-Over topologies, that initially covers the needs of RPL
   (RFC6550) data packets compression.  Using this dispatch type, this
   specification defines a method to compress RPL Option (RFC6553)
   information and Routing Header type 3 (RFC6554), an efficient IP-in-
   IP technique and is extensible for more applications.

1.  Introduction

   The design of Low Power and Lossy Networks (LLNs) is generally
   focused on saving energy, a very constrained resource in most cases.
   The other constraints, such as the memory capacity and the duty
   cycling of the LLN devices, derive from that primary concern.  Energy
   is often available from primary batteries that are expected to last
