                    Anchorless mobility through hICN
                    draft-auge-dmm-hicn-mobility-01

Abstract

   This document first dicusses 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 [I-D.muscariello-intarea-hicn].  The document then
   focuses on two main cases: the end-point sends data (data producer)
   or the end-point receive data (data consumer).  These two cases are
   taken into account entirely to provide anchorless mobility management
   in hICN.
