[DMM] Where to place mobility functions

[Charlie P.]

Hello folks,

One difference is that a mobile node is likely to be located in a network that supports mobility, whereas the network hosting a general CN may not have any mobility support features.

Regards,
Charlie P.

Hi Alper,

Is there any essential difference between placing the mobility function closer to the user  and placing

the mobility function closer to the CN?   I think in some sense the user host and it’s corresponding node are the same for mobility management protocol.

So what’s the reason to distinguish between them?

 

BR,

Jouni,

 

Thanks for the text.

 

      DMM can be used to realise such a distributed deployment

      model, by distributing mobility functions more closer to the user.

 

 

This part excludes the approaches that place the mobility function on or near the CN.

 

I recommend the following revision:

 

 

      DMM can be used to realise such a distributed deployment

      model, by distributing mobility functions more closer to the user

      and/or its corresponding nodes.

Folks,

DMM WG has done some progress lately. The requirements document has
already left the building and the gap analysis is heading to WGLC as
we speak. It is about the time to think what we should do next now
that we have grown out of the infancy.

A smaller group of mobility enthusiasts have been discussing about
possible next steps and how the possible new charter would look like.
The current very draft text template can be found here:
     https://github.com/jounikor/dmm-re-charter

As you can see, we are still in early stages and all input it welcome.
Obviously, possible re-chartering depends on many things. For example,
things like getting the gap analysis out of the WG and what the IESG
says. Nothing has been fixed or decided yet. Anyhow, we will start the
discussion on re-chartering with the expectation that the DMM WG will
re-charter and continue developing new solutions and/or enhancements
in the IP mobility space.
