  MAP-Me : Managing Anchorless Mobility in Content Centric Networking
                       draft-irtf-icnrg-mapme-02

Abstract

   Consumer mobility is supported in ICN by design, in virtue of its
   connectionless pull-based communication model; producer mobility
   though is not natively supported.  This document describes MAP-Me, an
   anchor-less solution to manage micro-mobility of content producers in
   the CCN (Content Centric Networking) and NDN (Named Data Networking)
   architectures, with support for latency-sensitive applications.  MAP-
   Me consists in the combination of two data plane protocols, triggered
   by producer movements, and leveraging ICN named-based data plane.
   The main protocol consists in a lightweight FIB update process,
   complemented by a mechanism of local notification and scoped
   discovery suitable for low latency applications and fast mobility.
