           Multicast Mobility in Mobile IP Version 6 (MIPv6):
                   Problem Statement and Brief Survey

Abstract

   This document discusses current mobility extensions to IP-layer
   multicast.  It describes problems arising from mobile group
   communication in general, the case of multicast listener mobility,
   and problems for mobile senders using Any Source Multicast and
   Source-Specific Multicast.  Characteristic aspects of multicast
   routing and deployment issues for fixed IPv6 networks are summarized.
   Specific properties and interplays with the underlying network access
   are surveyed with respect to the relevant technologies in the
   wireless domain.  It outlines the principal approaches to multicast
   mobility, together with a comprehensive exploration of the mobile
   multicast problem and solution space.  This document concludes with a
   conceptual road map for initial steps in standardization for use by
   future mobile multicast protocol designers.  This document is a
   product of the IP Mobility Optimizations (MobOpts) Research Group.
