                    Anchorless mobility through hICN
                    draft-auge-dmm-hicn-mobility-02

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) [I-D.muscariello-intarea-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.
