                    Anchorless mobility through hICN
                    draft-auge-dmm-hicn-mobility-04

Abstract

   This document first discusses the use of locators and identifiers in
   mobility management architectures, and their implication on various
   anchorless properties.  A new architecture is then proposed that is
   purely based on identifiers, and more specifically names as defined
   in Hybrid-ICN (hICN).  The document then focuses on two main cases:
   the end-point sends data (data producer) or the end-point receives
   data (data consumer).  These two cases are taken into account
   entirely to provide anchorless mobility management in hICN.
