The Mobile IPv6 mobility-management protocol enables minimum routing paths
between a mobile node and a correspondent node, which may itself be mobile.
This feature is called route optimization. Route optimization requires
authorization of initially unacquainted and untrusted parties. A so-called
return-routability procedure was integrated into the Mobile IPv6 in order
to do this securely. The return-routability procedure equips the mobile
node with cryptographic tokens that authenticate the mobile node and prove
the mobile node's presence at a claimed new location after movement.
Recently, a number of improvements or optional alternatives have been
suggested to the standard procedure. The primary driver between these
improvements is oftentimes further reduction of signaling messages and
latency, but other improvements such as better security have also been
suggested. This document discusses the potential goals for future
enhancements of route optimization, the security threats that such
enhancements must consider, and the various enhancement proposals and their
key ideas. An evaluation of some recent proposals is included, as well as a
discussion of how significant the Mobile IPv6 related optimizations are
related to other ongoing optimization efforts. Finally, needs for future
research are outlined.
