Luo,

I think “existing network deployments which are not DMM enablded” are included 
in “existing network deployments.

The end result is the compatibility with existing network deployment and end 
hosts. So whatever the dmm solution needs to do to ensure such compatibility. 
Do you agree?

Hi Anthony:

It seems the REQ-4 is changed a lot. Interworking between trusted 
administrative domains is good to me, and the interworking with existing 
network deployments which are not DMM enablded is also very important. I 
believe we have already have consistency about this.  So, how about mergering 
this two parts as following ?

---------------------------------------------------------------------------------
The DMM solutions SHALL support existing network deployment with IPv6 (e.g. 
existing IPv6 address assignment), be compatible with other mobility protocols, 
and be interoperable with the network or the mobile hosts/routers that do not 
support the DMM enabling protocol so that the existing network deployments and 
end hosts are not broken. Furthermore, the DMM solution MUST NOT break when 
being deployed between trusted administrative domains and SHOULD allow 
inter-working with the security measures deployed between these domains.
---------------------------------------------------------------------------------

Hope this make sense.

Re: [DMM] draft requirement REQ-4: compatibility







Replacing REQ-4 with the following:

REQ-4: compatibility
The DMM solution MUST NOT break when being deployed between trusted 
administrative domains and SHOULD allow inter-working with the security 
measures deployed between these domains. Existing network deployment and end 
hosts also SHOULD NOT break.

An attempt to clean up the text for REQ-4:

REQ-4: compatibility
The DMM solutions SHALL support existing network deployment with IPv6 (e.g. 
existing IPv6 address assignment), be compatible with other mobility protocols, 
and be interoperable with the network or the mobile hosts/routers that do not 
support the DMM enabling protocol so that the existing network deployments and 
end hosts are not broken.
REQ-4M (Motivation for REQ-4)
Motivation: The motivation of this requirement is not to break existing network 
deployments and end hosts.
OTHER related problem
O-PS3: Complicated deployment with too many variants and extensions of MIP
Deployment is complicated with many variants and extensions of MIP. When 
introducing new functions which may add to the complicity, existing solutions 
are more vulnerable to break.

I think that's a reasonable simplification.  We need a strategy for
backwards compatibility.
