Abstract
We discuss the issue of mobility in Nimrod. While a mobility
solution is not part of the Nimrod architecture, Nimrod does require
that the solution have certain characteristics. We identify the
requirements that Nimrod has of any solution for mobility support.
We also classify and compare existing approaches for supporting
mobility within an internetwork and discuss their advantages and
disadvantages. Finally, as an example, we outline the mechanisms to
support mobility in Nimrod using the scheme currently being developed
within the IETF - namely, the Mobile-IP protocol.

1 Introduction
The nature of emerging applications makes the support for mobility
essential for any future routing architecture. It is the intent of
Nimrod to allow physical devices as well as networks to be mobile.
Nimrod, as a routing and addressing architecture, does not directly
concern itself with mobility. That is, Nimrod does not propose a
solution for the mobility problem. There are two chief reasons for
