1.  Introduction

   The Mobile IPv6 Fast Handover protocol [2] has been proposed as a way
   to minimize the interruption in service experienced by a Mobile IPv6
   node as it changes its point of attachment to the Internet.  Without
   such a mechanism, a mobile node cannot send or receive packets from
   the time that it disconnects from one point of attachment in one
   subnet to the time it registers a new care-of address from the new
   point of attachment in a new subnet.  Such an interruption would be
   unacceptable for real-time services such as Voice-over-IP.

   The basic idea behind a Mobile IPv6 fast handover is to lev...
