Please check this updated REQ5 in draft-ietf-dmm-requirements-02:
REQ5: Compatibility
The DMM solution MUST be able to co-exist with existing
network deployments and end hosts. For example, depending on
the environment in which DMM is deployed, DMM solutions may
need to be compatible with other deployed mobility protocols
or may need to interoperate with a network or mobile hosts/
routers that do not support DMM protocols. Furthermore, a DMM
solution SHOULD work across different networks, possibly
operated as separate administrative domains, when allowed by
the trust relationship between them.
Motivation: The motivations of this requirement are (1) to
preserve backwards compatibility so that existing networks and
hosts are not affected and continue to function as usual, and
(2) enable inter-domain operation if desired.
This requirement addresses the following related problem O-PS2.
O-PS2: Complicated deployment with too many MIP variants and
extensions
Deployment is complicated with many variants and extensions
of MIP. When introducing new functions which may add to the
complexity, existing solutions are more vulnerable to break.
