                   draft-ietf-6lo-routing-dispatch-04

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.
